XCOM – Enemy Unknown is a turn based strategy reimagining of the classic game, XCOM UFO defense. After Earth is invaded by unknown alien hostiles, you are given command of the XCOM initiative to try and uncover the invasion plot and drive them out.
The game consists of story driven campaign missions with random events and alien invasions happening throughout, and multiplayer that allows you to take on a friend with teams comprising of both human and alien squad members. The campaign will take an average 20 hours to complete and will require a minimum of 5 playthroughs to earn all achievements.
While the game itself can be challenging and take several attempts before you find a strategy that works for you, the majority of the achievements are relatively simple and will unlock with little effort as you progress through the story.
The following playthrough strategy is designed to be the quickest way to unlock all achievements while minimising restart/reload times. (Please note, for the most part, the starting locations are interchangeable with playthroughs. It is entirely up to you where you start, as long as you start in a different location each time.)
NOTE: The endgame starts when you utilize the Gollop Chamber. If you are trying for certain achievements such as building all foundry items, don't enter the Gollop Chamber or it will prevent all future objectives.
Playthrough 1 –
Starting Location: North America
The purpose of this playthrough is to familiarise yourself with the game and discover what strategies work best for you. Most of the easier and story related achievements will unlock throughout this playthrough but don’t go out of your way to earn as many as you can until you have a solid understanding of the game and how it works.
With the bonus related to having a base in North America being reduced cost and maintenance of aircraft and aircraft weapons, it is a good idea to try and unlock ‘Shooting Stars’ and ‘Hunter/Killer’ on this play through.
Overall, this playthrough will net you roughly 20-25 of the achievements, most of which will be story related.
DLC: If you are planning on playing the DLC, keep a save from your first play through from immediately prior to entering the Gollop Chamber. When you are ready to play the DLC, download it and then load this pre-Gollop Chamber save. With your advanced end-game ready soldiers, you can stroll through the DLC in about an hour (presuming your first play through is on easy)
Playthrough 2 –
Difficulty: Easy or normal
Starting Location: South America
Although playing this playthrough on easy will make some achievements easier, playing on normal may serve as a nice easement to the later playthroughs on classic and impossible difficulty. The main focus of this playthrough will be to unlock the remaining achievements that don’t require classic or impossible difficulty.
Focus on the following achievements during this playthrough: ‘Ain’t No Cavalry Comin,’ ‘The Hardest Road,’ ‘As a Scalpel,’ ‘Edison,’ ‘Skunkworks’ & ‘Flight of the Valkyries’
With the bonus related to having a base in South America being reduced instant alien autopsies, it is a good idea to try and unlock ‘All employees must wash hands’ on this play through.
At the end of this playthrough you should have at least 40 achievements with a maximum of 43
Playthrough 3 –
Starting Location: Europe
This playthrough will allow you to focus on the achievements requiring you to be playing on at least classic difficulty. It also serves as an introduction to the harder difficulties but after 2 playthroughs already, you should have a decent understanding of how the game plays and already have the majority of achievements, leaving you to focus on the following during this playthrough: ‘Lone Wolf,’ ‘Wet Work’ & ‘Earth First’
Also use this playthrough to mop up any other achievements you may have missed from earlier playthroughs, while Classic difficulty can be tough, trying to unlock achievements on Impossible or Ironman mode can be even tougher.
By the end of this playthrough you should have 46 achievements
Playthrough 4 –
Starting Location: Africa
The sole purpose of this playthrough will be to unlock ‘Our Finest Hour.’ By now you should have a fairly deep understanding of the game and how to overcome the alien invasion. Don’t be afraid to abuse the save game system, even if it means saving after every turn, as one wrong step or unlucky move can screw up everything.
By the end of this playthrough you should have 47 achievements
Playthrough 5 –
Difficulty: Classic/Ironman Mode
Starting Location: Asia
In terms of difficulty, playing on Classic should be easier than your Impossible playthrough but the limit of only one save game file will make this playthrough the hardest of them all. Again, try and focus only on getting through this playthrough and don’t try and also work on any achievements you may have missed (unless of course you strongly believe you can.)
Surviving this playthrough will unlock ‘No Looking Back’ and ‘A Continental Fellow’ and give you a total of 49 achievements.
All that’s required in Multiplayer is to win a single match which will unlock ‘Meet New People. Then Kill Them’ and can be easily boosted if need be.
If by chance you have missed any achievements, start a new game on easy and mop up the rest.
XCOM: Enemy Unknown will take time and patience to earn the full 1000:gsicon:. While the majority of the individual achievements are relatively easy, it can be the overall game that can make the achievements quite difficult, but by finding what strategies work and don’t work, and by having multiple saves files within each game, there shouldn’t be any need to restart an entire play through.
Cheats: Either in the barracks or when deploying soldiers for a mission, you can change the name to one of the following for a soldier with enhanced skills and performance. NOTE doing so will disable all achievements
(Heavy) Joe Kelly
(Sniper) Ken Levine
(Assault) Otto Zander
(Support) Sid Meier
http://www.xbox360achievements.org/i...1/5-t8wqY=.jpgNo Looking Back – 100:gsicon:
Beat the game in Ironman mode on Classic or Impossible difficulty.
Although you have the option of playing on either Classic or Impossible difficulty it will be much easier on Classic. Ironman mode means you have only one save file that autosaves after both you and the aliens have had your turn. Although the enemies will be challenging, the main difficulty you will face with this mode is the possibility of making a mistake or wrong decision and being decimated within a few turns, unable to reload a save allowing you to correct this.
You will need to have a solid understanding on how the game plays and what strategies work in each situation. It is highly recommended you attempt a play through on Classic difficulty prior to starting Ironman Mode, as trying to go from Easy or Normal to Classic/Ironman Mode can be overwhelming.
See 'Our Finest Hour' for more on how the difficulties differ.
For a detailed walkthrough/strategy guide on beating Classic/Ironman Mode refer to the Classic/Ironman Mode Walkthrough
You can also find additional gameplay and Ironman mode tips HERE
TIP: (Credit to asdfen) To avoid the ‘one save’ rule you can sign out of your profile before the enemy finishes their turn and rollback a single turn.

http://www.xbox360achievements.org/i...1/5-0kqsc=.jpgOur Finest Hour – 90:gsicon:
Beat the game on Impossible difficulty
It is highly recommended you have a thorough understanding of how the strategy elements and mechanics of the game work before attempting the game on Impossible. The greatest challenges you will face on Impossible difficulty is the skill and tactics of the aliens and the reduced funding/rewards you earn each month.
The following outlines the difference between each difficulty level:
The key to beating Impossible difficulty is taking your time and knowing the strengths and weaknesses of the aliens and how to counter them with your own soldiers and research projects. Overall there is no one way to beat the game and will depend on your own style and strategies.
Make use of the save system and be sure to have multiple save files going at once. You may find yourself saving after every 2 or 3 turns in case something goes horribly wrong or you just want to give a turn another try. It is also a good idea to make a save at the beginning of each mission (after you land on the ground, not before at the base as the missions will be random) so you can restart if you find yourself employing a strategy that is destined to fail.
NOTE: The percentage outcome of both yours and the alien's shots landing is decided at the start of each turn. So saving directly before taking a shot and reloading if the shot misses is pointless. You need to save at the end of the previous turn to alter the outcome of your shots.
Overall, as long as you take your time, abuse the save system and research/upgrade equipment and satellites regularly, this won’t be overly difficult. Completing the game on Impossible will also unlock 'Earth First'
For a general walkthrough and combat tips/build, refer to the Classic/Ironman Mode Walkthrough as many of these will also apply to Impossible difficulty.
http://www.xbox360achievements.org/i...1/5-iGQT4=.jpgLone Wolf – 20:gsicon:
Clear a UFO crash site with one soldier on Classic or Impossible difficulty
This can only be done on a crash site mission and requires a single soldier to kill all aliens on the map. Although it can be completed on ether Classic or Impossible difficulty, it will be much easier on Classic.
The easiest mission to achieve this will be the Small Scout crash sites, as they only have anywhere between 5-8 enemies. Small Scout UFOs will appear early in the game, then randomly towards the end. If you choose to attempt this late in the game, then any or your upgraded soldiers with decent weapons and armor shouldn’t prove too difficult to clear the map on their own.
An alternate strategy is to do this on the very first crash site mission as this is guaranteed to have 4 Sectoids and an outsider. Start a new game, disable the tutorial as this gives you better odds of one soldier being chosen as an Assault. Play through the 2nd mission (abduction) focusing on ranking up your Assault soldier to corporal, (or Squaddie if you missed out on the first mission) and at the end choose the ‘Tactical Sense’ perk. An alternate to the assault class is the sniper utilising the Snap Shot and Headshot ability.
Make sure to save before you deploy to the crash site. (This will mean that every time you reload you receive a different map but this shouldn’t make a big difference to the strategy.) Once on the ground, move up one side of the map slowly. Ideally you want to engage the Sectoids two at a time. With a little luck, 1 of the 2 Sectoids you uncover will mind merge with the other. If this is the case use Run and Gun to move into a position to take out the one doing the mind merging, so that by killing it, you also take out the 2nd Sectoid. If using a sniper, be sure to use headshot on the mind merging Sectoid or take out the Sectoid posing the greatest threat first.
Be sure to reload, and hunker down for 2 turns to recharge your Run and Gun, then repeat for the other 2 Sectoids. Sometimes you won’t be able to get close enough to make use of Run and Gun, so fall back on moving once and using a grenade. Also sometime the Sectoids won’t mind merge, so it is best to fall back and engage them one by one.
Once you have cleared the Sectoids, move up to the UFO and take up position at the front near the door. Do not approach from the side as this can often mean the Outsider will spawn on your second move. Once you are near the door, end your turn, then open the door to make the Outsider spawn. Chances are it will run directly for you. Move inside the UFO giving yourself a clear shot and take out the Outsider. The achievement will unlock on the mission results screen.
This achievement relies heavily on luck so it may take several times to get the right alien placement/strategies before it works in your favor.
NOTE: Some people have reported this achievement to be glitched and will not unlock if you reload a save at any point during the mission. A good strategy is to make a save before leaving the base and reload from that point if you die during the mission.
http://www.xbox360achievements.org/i...1/5-i1eCI=.jpgBada Boom – 10:gsicon:
Kill 50 aliens with explosive weapons
This requires you to make a kill using either a grenade or rocket launcher. All classes can carry grenades but only the heavy can use a rocket launcher. This should come naturally as you progress through the game but a good strategy, is to use grenades and rockets on weaker enemies like Sectoids and Thin Men, as these tend to group up, or to finish off enemies who have low health. Once the 50th alien is killed the achievement will unlock. This carries across all playthroughs and does not have to be done in a single game.
TIP: Although you can only carry a limited number per mission, grenades are infinite, so it’s a good idea to use up each soldier’s grenade supply each mission.
http://www.xbox360achievements.org/i...1/5-mKWjA=.jpgWelcoming Committee – 20:gsicon:
Kill 150 aliens
-See ‘Pale Horse’
http://www.xbox360achievements.org/i...1/5-4Dvsk=.jpgPale Horse – 50:gsicon:
Kill 500 aliens
This will unlock naturally as you progress through the game as the main purpose of most missions is to kill all aliens. Depending on how many side missions you choose to complete, this may take more than one play through.
http://www.xbox360achievements.org/i...1/5-8N6NA=.jpgShooting Stars – 35:gsicon:
Shoot down 40 UFOs
To shoot down a UFO you will need a satellite and at least one interceptor. Once a satellite has detected a UFO via scanning the geoscope in mission control, you need to launch an interceptor in the hope of bringing it down. In the beginning of the game this will be fairly easy but as the game progresses, you will need to upgrade not only your interceptors themselves but also their payload to be able to take out the alien’s larger UFOs.
A good strategy is to hanger at least one interceptor per continent with a satellite in orbit. On average you will encounter 1 or 2 UFOs per month so unless you hold off progressing the story, this will take you several playthroughs.

http://www.xbox360achievements.org/i...1/-p6arg==.jpgAin’t No Calvary Comin’ – 50:gsicon:
Have a soldier survive every mission in a full game
This requires a single soldier to not only participate, but also survive every mission in a full game. It is highly recommended this be attempted on easy difficulty but can be achieved on any difficulty.
Unless you are lucky, you will need to make good use of the save game system, reloading if your chosen soldier dies or sustains massive damage. While it may be tempting to keep them towards the back of the map, it is a good idea to use them as the main soldier in your squad, as participating in every mission will allow them to rank up quickly, making them a powerhouse in the later stages of the game.
It is also worth mentioning that your soldier can sustain some damage, as often they will heal in time for the next mission, but this is risky as a mission can pop up at anytime.
Once you complete the final mission and ‘win’ the game, the achievement will unlock.
TIP: (Credit to asdfen) When selecting a new game, disable the tutorial as this will give you four soldiers to start with, so you will have a better chance of at least one making it through every mission.
http://www.xbox360achievements.org/i...1/5-lVgLE=.jpgAs A Scalpel – 25:gsicon:
Earn the ‘Excellent’ rating in every performance category on a terror mission
This can be done on any ‘Terror’ mission. The following are the 3 categories and requirements for an ‘excellent’ rating:
- Aliens killed: Kill all aliens on the map
- Operative lost: No squad members can be killed
- Civilians rescued: At least 75% rescued.
The hardest part of this achievement will be rescuing civilians, as the aliens will not waste any time killing them. Unlike some other missions, you will need to play offensively, taking the fight to the aliens quickly. Try and focus most of your attention on killing aliens, instead of rescuing civilians as you can always double back or use a weaker squad member to rescue them later. When engaging aliens, particularly Chryssalids, make sure you focus all your fire on one and kill it, before moving on to the next. In Terror missions, having three wounded aliens is much more dangerous than one enemy at full health.
As long as you have received a rating of ‘excellent’ in all 3 categories, the achievement will unlock during the mission results screen.
TIP: Outfit your squad with ‘assault’ and ‘heavy’ classes as these are better suited to close quarter combat, and (your assault soldiers) can utilise the ‘Run and Gun’ perk. Also to make this achievement easier, outfit a squad using your most experienced soldiers.
http://www.xbox360achievements.org/i...1/5-3xdvM=.jpgEdison – 25:gsicon:
In a single game, complete every Research Project.
Research projects become available after killing aliens, capturing aliens, completing Crash Site/Base missions or by completing prerequisite research. The number of scientists and laboratories constructed will determine the research time of each project. You can increase the overall research speed of projects by adding additional scientists to your staff, by successfully completing missions that offer scientists as rewards, receiving scientists from the council for having satellites in Europe, North America, South America and Africa, and by building additional laboratories. Keep in mind that some research projects will require additional materials, like alien materials or alloys, so try and keep a small supply on hand at all times.
There are a total of 53 projects and all will need to be completed in a single game. You can always check what projects have been researched by selecting the Research Archive in the laboratory menu. The following are the different research projects and how they can be obtained.
Also try and capture each alien as soon as they start to appear on missions, as waiting until later levels can be difficult when attempting to capture several at once. Aliens like Sectoids and Thin Men become less frequent on later missions. When capturing tougher enemies, rely on your veteran soldiers, as you will most likely take a few hits and this will mean instant death for rookies. Also be sure to upgrade your Arc Thrower in the foundry when the upgrade becomes available later in the game. This will mean you can stun an enemy without having to wear down its health first.
http://www.xbox360achievements.org/i...1/-35iPQ==.jpgAll Employees Must Wash Hands – 10:gsicon:
In a single game, complete every Autopsy
Each autopsy is conducted via the laboratory and will require an alien corpse to do so. Each time an alien is killed, its corpse will be automatically collected at the end of the mission. There are a total of 13 alien autopsies required and all will need to be completed in a single game.
http://www.xbox360achievements.org/i...1/5-7eKV8=.jpgEye in the Sky – 5:gsicon:
Launch a Satellite
This will unlock as you progress through the story. After the 3rd mission you will be instructed to launch a satellite over a country. Select any country and you will be given a time frame for when the satellite will be active. Once the number of days have passed you will receive a notification the satellite is in orbit and the achievement will unlock.
http://www.xbox360achievements.org/i...1/+tyJxA==.jpgAll Together Now – 10:gsicon:
Get satellite coverage over every country on one continent
To launch a satellite you first need to ensure you have the correct facilities built in your base. Doing this will require you to clear additional space and build access lifts to reach lower levels. You will need to construct additional workshops to allow additional engineers to work in your base. Next you need to build power generators which in turn allows you to build a satellite uplink.
Once this is done select the build satellite option from engineering. Once the satellite has been built visit the situation room to launch it. Repeat the process until there is one satellite over every country in a single continent. Once the last satellite is launched and has moved into position in space, the achievement will unlock.
TIP: Wait until you start in South America (only has 2 countires) before attempting this achievement as you will automatically have a satellite over one country when you choose your starting base, then follow the method above and launch the second satellite over the remaining country.
http://www.xbox360achievements.org/i...1/5-ldyxM=.jpgHunter/Killer – 15:gsicon:
In a single game, shoot down one of each alien craft
To increase the chances of detecting a UFO, be sure to constantly produce and launch satellites around the globe. Also be sure to have at least one interceptor based at each country with a satellite, (preferably 2 with different armaments). As new armaments become available to research and build, give them priority as they will be the key to bringing down the different types of UFOs. When available, prioritize the Firestorm as these are essential to shooting down the largest UFOs.
The following are the 6 UFO types that need to be shot down in a single game:
After you have shot the UFO down, the next screen will show you what type of UFO it is. (Bottom left corner)
http://www.xbox360achievements.org/i...1/5-lmua0=.jpgMan No More – 10:gsicon:
Build a suit of powered armor
There are 3 types of powered armor, Archangel, Ghost and Titan armor. All 3 are researched via the laboratory and built via engineering. You will most likely research these as you progress through the game but they will not be available until later in the game. Once the armor is built, the achievement will unlock.
http://www.xbox360achievements.org/i...1/5-wosck=.jpgWe Happy Few – 10:gsicon:
Complete a mission without losing a soldier
This requires all members of your team to survive the mission. They can take damage but cannot die. This is best done on an easier difficulty and towards the beginning of the game as most of the aliens you face will be Sectoids. This can be unlocked as early as the 2nd mission.
TIP: Take it slow and don’t rush. Try and focus on 1 or 2 aliens at a time and don’t spread your team too far apart. If one team member sustains damage, move them towards the back and bring your full health members up.
http://www.xbox360achievements.org/i...1/5-lu8g8=.jpgThe Hardest Road – 10:gsicon:
Advance one of your soldiers to Colonel Rank
Colonel rank is the highest a soldier can achieve and will require them to be present in most missions. Soldiers rank up by damaging/killing/capturing aliens, performing actions like firing while on overwatch/suppressing, and surviving missions unharmed. Reaching the rank of Colonel will take time and require a single soldier to be present on most missions throughout the game. It’s a good idea to use higher ranked soldiers as the driving force when attacking, as performing more of the actions mentioned above will result in faster promotions. Also remember, when ranking up and choosing perks, choose perks that suit your play style allowing you to utlilise the soldier more effectively.
TIP: It is a good idea to work on this achievement while going for ‘Ain’t no cavalry comin’ because if you use the same soldier on every mission, they will reach colonel easily. You can also buy the 'Wet Work' perk from the Officer Training School for 125 credits that grants soldiers additional experience per kill.
http://www.xbox360achievements.org/i...1/5-urU4U=.jpgWorth Every Penny – 20:gsicon:
Acquire 1000 credits in one month
You will receive credits on a monthly basis from the council and your monthly income is dependent on how many satellites you have in orbit and how many countries are currently still part of the council. You can earn additional money throughout the month as rewards from completing certain missions, fulfilling council requests, and by selling materials and alien corpses on the grey market.
1000 a month may come naturally, however if you find you are struggling, save your game then start selling most of your equipment/recovered tech on the grey market. Once the achievement unlocks, reload the save.
TIP: Playing on Easy or Normal difficulty will make this achievement easier to unlock, as it will be easier to manage the panic levels and allow for continued full support from the council each month.
Also having a starting base in Africa will increase your monthly council funding by 30%.
http://www.xbox360achievements.org/i...1/5-zEUlQ=.jpgOppenheimer – 20:gsicon:
Staff the Research Labs with 80 scientists
Additional scientists can be obtained as rewards for completing certain missions, (mainly abduction missions,) monthly rewards for having satellites in Europe, North America, South America and Africa (the more satellites, the more scientists you will receive each month,) and from the occasional council request. Once you have a total of 80 scientists, the achievement will unlock. This will most likely come naturally towards the later stages of the game
TIP: If the achievement does not unlock naturally over the course of the game, start a new game on easy and focus on completing tasks/launching satellites that will net you the most scientists. If given the option between adding scientists or engineers, always choose scientists.
http://www.xbox360achievements.org/i...1/5-8Fo3I=.jpgOne Gun at a Time – 20:gsicon:
Staff the Engineering Department with 80 engineers
Additional engineers can be obtained as rewards for completing certain missions, (mainly abduction missions,) monthly rewards for having satellites in Asia, North America, South America and Africa (the more satellites, the more scientists you will receive each month,) and from the occasional council request. You can also add additional engineers by building additional workshops. Once you have a total of 80 engineers, the achievement will unlock. This will most likely come naturally towards the later stages of the game.
TIP: If the achievement does not unlock naturally over the course of the game, start a new game on easy and focus on completing tasks/launching satellites that will net you the most engineers. If given the option between adding scientists or engineers, always choose engineers.
http://www.xbox360achievements.org/i...1/5-qvAyk=.jpgSkunkworks – 20:gsicon:
In a single game, complete every Foundry project
Each foundry project will require either money, alien materials, previous research, engineers or a combination of all. There are a total of 18 projects and all will need to be completed in a single game.
http://www.xbox360achievements.org/i...1/5-pD4LQ=.jpgYou Have 5 Seconds to Comply – 10:gsicon:
Build a S.H.I.V.
Before you can build a SHIV, you first need to build a foundry. From here you can research heavy weapons platform. Once this is done, proceed to engineering and build the S.H.I.V. Once construction is complete, the achievement will unlock.
http://www.xbox360achievements.org/i...1/5-4JuHw=.jpgTheory… - 10:gsicon:
Build a Laboratory
Once you have 6 or more scientists, the option to build a laboratory becomes available from the 'Construct Facility' menu. A laboratory will require 3 power, 6 scientists and 125 credits to build. Select an excavated section of your base and after the required number of construction days have passed, the achievement will unlock.
TIP: Having a base or full satellite coverage in Europe will reduce the required credits to 62.
http://www.xbox360achievements.org/i...1/+R144g==.jpg…and Practice – 10:gsicon:
Build a Workshop
Once you have 6 or more engineers, the option to build a workshop becomes available from the 'Construct Facility' menu. A workshop will require 3 power, 6 engineers and 130 credits to build. Select an excavated section of your base and after the required number of construction days have passed, the achievement will unlock.
TIP: Having a base or full satellite coverage in Europe will reduce the required credits to 65.
http://www.xbox360achievements.org/i...1/5-hqoqM=.jpgWet Work – 10:gsicon:
Complete a Very hard abduction mission in five turns or less on Classic or Impossible difficulty
This can be a difficult achievement as finding a 'very hard' abduction mission can take time. To increase your chances, try and raise the panic level in one continent. The higher the panic level, the harder the mission will be.
As there is a limited number of maps and the rotation is random, it may also help if you wait until you receive a map you know well and are confident you can get through quickly. Just be sure to save your game at the base before launching the mission.
Your soldier load out is entirely up to you but it is highly recommended you have a minimum of 5 soldiers and trying to clear a very hard mission with only 4 is near impossible.
The easiest way to beat the mission in five turns or less, is to start off by proceeding through the map learning what enemies are present and where they are located. Then reload the save you made at the start of the level and run through with that knowledge. Their positions and strategies may vary slightly but overall you should know what to expect.
TIP: Despite the option of Classic or Impossible, this will be much simpler on Classic
http://www.xbox360achievements.org/i...1/-L+TGw==.jpgA Continental Fellow – 50:gsicon:
Win the game from each of the 5 starting locations
Each time you start the game you are given the option of what continent you wish to establish your base on. Each location has its own bonuses that can affect certain aspects of the game, but overall there is no great difference with each location.
This will take 5 playthroughs to unlock as long as you choose a different starting location with each new game. How you play and progress through the game is entirely up to you but be aware that you need to win the game. Having more than 8 countries pull out of the council will result in a loss and void that particular playthrough for this achievement.
http://www.xbox360achievements.org/i...1/5-pLqxY=.jpgWhat Wonders Await – 5:gsicon:
Complete a Research Project
This is story related and cannot be missed. After the 2nd mission you will be instructed to visit the lab where you will need to authorise a research project using alien materials. Either select the S.C.O.P.E or medkits. It will take several days to complete the project but you will receive a notification when it is ready and the achievement will unlock.
http://www.xbox360achievements.org/i...1/5-3ISVo=.jpgUp and Running – 5:gsicon:
Build a base facility
This is story related and cannot be missed. After the 3rd mission you will be instructed to build an alien containment facility. Once you give the go ahead and wait the required number of days, the achievement will unlock.
http://www.xbox360achievements.org/i...1/5-7WYv0=.jpgCombat Ready – 5:gsicon:
Build an item
This is story related and cannot be missed. Once you complete ‘What wonders Await’ you will be directed to the engineering department and instructed to build the item you just researched. Select the number of items you want made and the achievement will unlock.
http://www.xbox360achievements.org/i...1/5-82mm4=.jpgDrums in the Deep – 10:gsicon:
Gain access to the lowest level in your base
To expand your base to the next level below, you need to build an access lift. Each access lift requires money (the cost increases with each additional lift) and will take several days to finish construction. There are only four levels, so once the fourth access lift has been constructed, the achievement will unlock. This will most likely come naturally as you progress through the game and expand your base.
http://www.xbox360achievements.org/i...1/5-0f2Hk=.jpgHappy to Oblige – 15:gsicon:
Fulfill a Council request
Council requests will appear at random times via the situation room. These will involve a council nation requesting either alien technology/artifacts, items you can/have engineered, or satellites to be launched in exchange for rewards. Each request will carry a certain time limit allowing you to build/obtain the required items. Once you meet the requirements, the request will be completed and the achievement will unlock.
TIP: While most items will be fairly easy to build/obtain within the time limits, satellites will take longer to build then the allowed time, so it’s a good idea to always have a satellite in reserve so it can be launched quickly.
Also, the council requests are random, so if you receive a request that you don’t believe you can fulfill, don’t go out of your way, instead wait until an easier request comes along.

Shoot down a UFO
This is story related and cannot be missed. After the 3rd mission you will be called to mission command where you need to launch an interceptor to shoot down a UFO. Once you have confirmed the launch, it will engage the UFO and shoot it down, unlocking the achievement.

Win a multiplayer match
This requires you to win a multiplayer match and has to be done online. (no split screen/system link) The multiplayer consists of an allocated number of points which can be spent on creating a team of both human and aliens soldiers. The game will play out the same as the single player and will be over when one player eliminates all members of their opponent’s team.
This will require skill and strategy when going up against randoms but can be easily boosted by having one player skip their turn until all their soldiers have been killed.

Mind Control an Ethereal. Single player only
(Credit to red_hammer for this strategy) Most important for this achievement is, that your Psi-Soldier has Psi-Inspiration as well as Mind Control and the Psi-Armor. You want your Psi-Soldier to have around 100 Will (more is better) with the Psi-Armor.
When you engage an Ethereal:
-Leave your Psi-Soldier out of sight of the Ethereal (even your Psi-Soldier can be mind-controlled and then you have to kill the Ethereal instead of mind controlling it yourself.)
-In the turn before you attempt the Mind Control, use your Psi-Inspiration so you get a +30 Will Buff.
-Then attempt the mind control.
TIP: You can also have a Support skill perk, "Combat Drugs". The smoke grenades of this Support add another 20 Will.

Kill an alien while flying. Single player only
This can only be achieved while wearing the Archangel armor, which is unlocked later in the game. The easiest class to use for this is the sniper with the headshot ability, as this will give you the greatest chance to kill an enemy without getting too close.
TIP: You may want to make a save at the start of the previous round before attempting this achievement in case the shot misses.

Find a soldier with the gift
This is story related and cannot be missed. To do this you need to send one of your soldiers to the Psi-Labs. The soldier with the highest 'Will' is chosen to have the gift. This will mean that the soldier you choose will be out of action for 10 days, so be sure it isn't your main soldier if you are also attempting 'Ain't no Cavalry Comin.'
http://www.xbox360achievements.org/i...1/5--jRlo=.jpgPrisoner of War – 10:gsicon:
Capture a live alien
This is story related and cannot be missed. Before attempting this you need to research the ‘Arc Thrower’ via the lab. (Researching the arc thrower is story related and will be available after researching Xeno-Biology) One the research is complete, construct it in engineering and outfit it on a soldier for the next mission.
Once you are in a mission you need to be close to an alien, (3 or 4 spaces from them and have a clear LOS.) Unless an alien approaches you, you will need to move close on your first turn, then use the arc thrower on your second turn. Press :rtbut: to select the arc thrower and fire. You only get one shot and there is still a chance you will miss so either reload a save, or have a second soldier standing by to try again if the shot misses. Otherwise the alien will go down and the achievement will unlock.

Build a Firestorm
In order to build a Firestorm, you will first need a power core from a UFO or Alien Base. (It needs to be a working power core. A damaged one recovered from a downed UFO will not work.) This will allow you to research 'New Fighter Craft.' Once the research has been completed, construct a Firestorm from the Hanger menu. Once the required days have passed, the achievement will unlock.
http://www.xbox360achievements.org/i...1/5-z3a0g=.jpgPoison Control – 10:gsicon:
Cure poison on five soldiers in a single mission. Single player only
Before attempting this, you will need to research/build medikits and equip at least five when on the load out screen. It is highly recommended you use a Support soldier with the 'Field Medic' perk as this will alow a single medikit to be used three times instead of once
The easiest way a soldier can become poisoned is by a Thin Man so it is a good idea to attempt this in an early objective based mission. (The Thin Men seem to be the main enemy in these missions.) There are two ways to be poisoned, either have a Thin Man spit poison at you or after you have killed one, move your soldier into the poison cloud it leaves behind.
Once a soldier becomes poisoned it must be treated by a soldier carrying a medikit. Just be sure that the soldier running into the cloud can't be carrying a medikit as this will make them immune. When five soldiers have been cured of poison, the achievement will unlock.
TIP: An easier method to achieve this is to try and isolate a Thin Man and have at least five of your soldiers close by. Have your first soldier move in close and make the kill. Once the Thin Man is dead and has left behind a cloud of poison, move each member within the cloud. On your next turn, set about curing everyone. Be sure to make a save before attempting this as it may take several tries.

Before setting out on a mission, make sure all team members are female. If you lack enough female soldiers to fill a squad, hire more from the barracks. (You can’t actually select male or female when hiring.) As long as you have an all female squad and win the mission, the achievement will unlock.

XCOM Enemy Unknown: Slingshot DLC
+ Estimated difficulty: 3/10
+ Offline: 5/5 - (100:gsicon:)
+ Online: 0/5
+ Minimum time to 100: 10 Hrs
+ Minimum playthroughs needed: 1
+ Cheats affect achievements: Yes, disables achievements (Canít use the hidden character codes)
+ Difficulty affects achievements: No
+ Missable achievements: 2 (Rising Dragon & All Aboard)
+ Glitchy achievements: 0
+ Unobtainable achievements: 0
The Slingshot DLC consists of 3 new missions on 3 new maps, a new character Zhang, and several additional customisable options for your squad members. The DLC is not stand alone content and requires you to start a new game as loading a save file prior to installing the DLC will not work.
The mission as relatively easy and shouldnít prove too difficult if you have already played through the game at least once. The new maps are very similar to existing ones so again, these shouldnít confuse or overwhelm you. The council missions can be played through in roughly 30 minutes (depending on how much time you spend on the in between missions)
During the first or second month (it will depend on how many missions you are offered in the first month) you will receive a council request. Once this happens you will be given the option of selecting a normal mission, or the DLC mission. From here the three missions will appear one after the other, so you should be all finished by month 3 or 4 (again, depends on the number of missions per month)
From here you simply need to keep the new character, Zhang, alive so you can include him in your squad for the final mission.
The Slingshot DLC is not difficult but can be time consuming as it requires a full playthrough to unlock the full 100. Overall, as long as you maintain plenty of save files and save regularly, all 5 achievements can be unlocked in 1 playthrough.
http://www.xbox360achievements.org/i...1/UPtTeWw=.jpgNew Friend - 10 http://www.xbox360achievements.org/images/site/gp-g.png
Complete Friends in Low Places.
During the first or second month (it will depend on how many missions you are offered in the first month,) you will receive a council mission and be given the option of a normal mission or the DLC mission. Select the DLC mission and complete it.
The mission follows the standard Ďextract VIPí formula. The new character Zhang, will take on the role of the civilian and will only have the hunker down ability. The map is very smaller and has only minimal enemies, mostly Sectoids and Thin Men. Just be careful towards the end of the mission as a Chryssalid will show up. Once Zhang reaches the Skyranger, the achievement will unlock.

Complete Confounding Light.
The next council mission you receive will be Confounding Light and will require you to activate 4 beacons and then proceed to activate the trainís main controls. The map is very similar to the other train station one encountered throughout the game. Again the enemies will be basic Sectoids and Thin Men, however this mission will have Mutons show up towards the end of the mission. Overall this is a relatively simple mission to anyone familiar with how the game is played.
NOTE: You arenít required to bring Zhang along on this mission in order to unlock the achievement.
http://www.xbox360achievements.org/i...1/UPiSiEo=.jpgThe Bigger They Are - 20 http://www.xbox360achievements.org/images/site/gp-g.png
After completing Confounding Light, the next council mission will be Gangplank. This mission takes place on a large Battleship, the layout of which is the same as the Battleship encountered in the late stages of the vanilla game. The mission requires you to deactivate 6 engine components, this is done by moving to an adjacent title and manually deactivating it or by using an explosive weapon.
This mission will have a range of enemies including Sectoids, Thin Men, Cyberdisks and Mutons but overall shouldnít prove too difficult as there arenít a large number of enemies and most of the time you will engage them one or two at a time. Once the 6th component has been deactivated, the achievement will unlock.
NOTE: You arenít required to bring Zhang along on this mission in order to unlock the achievement.
http://www.xbox360achievements.org/i...1/UPlycNk=.jpgRising Dragon - 30 http://www.xbox360achievements.org/images/site/gp-g.png
Take your new ally into the final challenge.
All that is required for this achievement is to ensure you have Zhang in your squad when launching the final mission on the temple ship. Once the Skyranger lands and you have control of your squad, the achievement will unlock.
NOTE: This is missable because if you donít have Zhang included in your squad, you will be forced to either load an earlier save or restart the entire game. Also be sure that Zhang doesn't die if you take him on missions prior to the final mission. If he does, you will be forced to reload a previous save or restart from the beginning.
http://www.xbox360achievements.org/i...1/UPzQmyA=.jpgAll Aboard - 30 http://www.xbox360achievements.org/images/site/gp-g.png
Complete Confounding Light with more than 3 turns left on the timer.
The mission begins with 10 turns on the timer and the achievement requires you to finish with more than 3 turns left by the end. Unlike most other missions, this mission doesnít require you to eliminate all enemies on the map in order to finish, instead, all that is required is the 4 beacons and the train controls be activated. I highly recommend you save your game at the start of the mission so that in the event you donít meet the requirements, you can reload and try again, otherwise you will need to start a new playthrough.
The method to completing this will depend largely on the type of classes in your squad and your general play strategy but you will need to play offensively. A good strategy is to have 2 or 3 soldiers move up the interior of the train, 1 soldier move up the right hand side and 2 soldiers, preferably one of them a sniper, move up the left hand side or along the top of the train.
The main focus of 1 or 2 of the soldiers inside the train should be to dash to the beacons while only firing on enemies as a last resort or to help thin the herd and using the 3rd to protect the others. The occasional enemy will take up cover inside the train but most will take move to either side allowing you remaining soldiers to engage them. You should be able to activate the first 2 beacons with 7 or 8 turns left on the timer. Some time after activating the 2nd beacon, a muton will show up. (Itís position may vary slightly but will most likely show up on top of the train. If you have a soldier moving along the top of the train, this wonít be too much of an inconvenience. However, if you donít, then at this stage i suggest moving all your units into the train as a muton with a height advantage can be deadly.
Keeping pushing through the train with at least 1 soldier dashing to the 4th beacon and another dashing for the very front of the train. Once all 4 beacons are activated, use your furthest soldier to reach and activate the main controls. Provided you have 4 or more turns left on the timer, the achievement will unlock.
Overall this is the hardest achievement as it requires you to take some degree of risk and is based on luck of shot outcomes.
TIP: You aren't required to clear all enemies in order to finish the mission, so if an enemy is out of range or doesn't pose too greater threat, leave them and concentrate on the beacons. Also having 6 squad members will make this achievement significantly easier than attempting it with only 4 or 5 soldiers.
For Flight of the Valkyries, easiest way to get female recruits would be to hire a new soldier from the barracks, then save when you have 1 day left before they arrive. Fast forward time and see if you get a female soldier. If not, just reload and try again as you will eventually get a female to appear.
Nice work Deg, looks very helpful.
I am just curious, for the research projects, or the foundry projects, etc, do you basically have "all the time in the world" to complete these, as long as you don't progress the story? Some of those research projects are quite long, and I'm worried that if I take them over the "Priority Research Project" that is for the story, that I will run out of time, or something like that. Can anyone say from experience either way?
ok this achievement is listed wrong, i just got it and will copy down all the research needed below:
New Fighter Craft
Light Plasma Rifle
Heavy Floater Interrogation
Muton Elite Interrogation
Sectoid Commander Interrogation
Thin Man Interrogation
Alien Nav Computer
UFO Power Source
Sectoid Commander Autopsy
Thin Man Autopsy
Heavy Floater Autopsy
Muton Elite Autopsy
GUIDED FUSION LAUNCHER
the last two in caps were the only ones i was missing for the achievement, they are found once you shoot down a UFO very large battleship and go to the crash site and beat the mission. you get the two research ideas from the crashed ship.
you DO NOT need to capture the 3 robotic units for interogation because you cannot capture them (drone, cyberdic, and sectopod)
Thanks for putting this up. Its looking great so far keep up the good work.
A very solid start with a lot of great information.
The only bit I have to add is that there are in fact cheats in this game, however they will disable achievements (which they should warn you about before you proceed).
If you enter in the name of certain Firaxis developer's you will unlock specific super soldiers that are premade and have tons of abilities. For example entering the name "Sid Meier" or "Ken Levine" are just two examples. A quick Google search will give you some others, but for the purposes of editing the roadmap I just wanted to let you know that they do exist and will disable achievements.
Great Guide, thanks.
@Silent, ah thanks man I was wondering how the hell to get my last 2 research, looks like i just need to spam searching for UFO's :).
Thanks for the guide dude, tough 1k but pretty great game.
My "Skunkworks" achievement will not fire....PC version. This guide is also wrong. There is more foundry projects not listed here like SHIV Suppression.
There are things missing, check again. I have everything on the list, plus more, no achievement fire.
Skunkworks requires 18 upgrades:
Heavy Weapons Platform
Improved Arc Thrower
Improved Pistol I
Improved Pistol II
Improved Pistol III
thats 16 not 18
This achievement is either bugged or there is an upgrade missing
It's 18. I left off Alien Grenades and Advanced Construction. Fixed.
got it now
One thing though: When you create a save before shooting and miss your shot, simply reloading the save won't give you another chance. In fact, Firaxis told in an interview that once your % chance has been calculated, or diced, it will stay that way. No matter how often you reaload.
I did not try it out, but it might be better to save before the whole round, instead of the shot. So you try it from a different position. That should 'recalculate' the whole system, again.
Another point came to my attention:
I can't stun Chryssalids (No Target available) - so.. there should be no way of interrogating them?
But as I already said in the PMs - great guide DEG23 :)
Before you take your position and shoot, I mean.
Because since you are in a totally different (or slightly different) position, it needs to be recalculated again. It's different than just being in position, saving, shooting, missing, reloading and trying again.
Let's say there's a statue and two positions (left and right). Firstly, I save.
Then I run to the left position, line up my shot, miss. Alright, reload:
Now I run to the right side, instead of left. Should be a totally different thing now, as far as I think. But someone needs to try that out and prove it. Just an idea.
EDIT: I have also updated the description for 'No Looking Back' with a series of tips and strategies to keep in mind when attempting Ironman mode.
The guide is 95% complete, there are a few achievements, like 'Hunter/Killer' i still need to test for a list of UFOs and the best weapon to take each one out, but overall each description and method should be correct.
Thank you again to everyone for their help with confirming the lists of projects and autopsies for achievements like Edison and Skunkworks.
May want to note that getting satellites over all the counties on a continent you didn't start on will also give you that bonus. For example, I started in North America and got "Air and Space". I put the 2 satellites needed over South America I get the "We Have Ways" bonus as well.
Also, what I am doing is not building the Alien Containment and building my satellite coverage to full coverage. The extra "bonuses" you get for having a satellite over each country (i.e. "Expert Knowledge") as well as the money you get every month really helps build up your power before getting too far along.
I would think this would help in the harder difficulty level playthroughs since you will have people with better weapons, armor, and accuracy before getting into the meat of the game.
Does not have to be 5 soldiers, can be done with 1 soldier 5 times. Just did a Bomb Disposal mission with all Thinmen. Had 1 soldier run in to the poison and out, cured then back in to get poisoned again. Done this way, each cloud is good for 2 poisonings.
Tip: Buff your Will with the Combat Drugs smoke grenade and Psi Inspiration ability. De-buff the Ethereal with Mindfray (it stacks).
Try to get a Support soldier with PSI abilities. Take Mindfray, Psi Inspiration, Mind Control, Smoke Grenade and Combat Drugs. Wear Psi Armor and equipping a Mind Shield would not hurt.
Great guide DEG, I'm thinking of getting this game looks cool but tough.
For the Poison Control cheevo there is an even easier way. Once you have mind control, take over a thin man and use free aim poison cloud on a group of your own guys. If you bunched them close enough you should get poison three guys at a time.
