Mass Effect is an action/RPG and is therefore a bit of a longer game story-wise. The achievements are not all that difficult if you play smart, but the game will take you a long time regardless. I finished my first play in 17 hours while taking in the story. The two final plays should be much quicker if you skip dialogue by hitting the X button. Don't hit it too fast though as you may accidentally select your next option on accident.

Note: I've received some feedback on my estimated time. It took me 32 hours to get 1050 in this game, so I assumed that was normal. Apparently it is not. As I mentioned my first play took 17 hours, but this was with me not liking the game much and just wanting to get through, not exploring any random planets, not doing any of the crazy searching missions to collect badges or minerals. If you do any of those, I guess you're looking at about double the time. If you just blaze through like I did, it can be relatively quick for you.

Step 1: Create a character.
It is highly suggested that you use a soldier class for the ability to wear heavy armor and the increased damage and health. When assigning your skill points, focus on armor, spectre and soldier to get all those increased quickly.

Step 2: Normal Difficulty
The first thing you want to do is work on the "Scholar" achievement inside the Citidal. There is only one missable entry, the Protheans, which you need to learn about from Captain Anderson just outside your ship. Make sure you exhaust all speech dialogue with him until you get it. During this first play, I would suggest getting the Asari (Liara) ally out of the way and using the Soldier (Ashley) to balance out your party since Liara is all Biotic. Follow the Ally achievement description to get Liara as soon as possible. Avoid all assignments until you have her and then continue to follow the Ally achievement description. If done correctly you will get Ashley at the same time as the "Completionist" achievement and Liara after completing Feros and Noveria, but before going to Virmire. Work on Paragon points during this play. Once you finish the game on Normal, you will unlock Hardcore.

Step 3: Hardcore Difficulty
You can start a new game and use an Existing ID to carry your character from play #1 over to this one. The enemies on this will be scaled up to your level making it slightly more difficult. Levels 51-60 will be unlocked so you can continue to progress. I used Kaiden and Garrus during this play. Follow the ally guide for this although it is much easier now. Work on Renegade points during this play. Finishing this play will unlock Insane difficulty.

Step 4: Insane Difficulty
Continue with your same character and the last two allies (if you followed so far it would be Tali and Wrex). The bosses in this are a higher difficulty than you so be a bit more cautious.

Step 5: Mopping Up
As a soldier you won't have any special abilities so you will need to create a new character as an Adept and one as an Engineer. Play until you have all their skills unlocked and then work on the 75 uses of each ability, casting them on the transit terminals. AI Hacking is the only one that has to be done on an enemy but it can be done very early against the turrets when you encounter Fist. Same right before that and just reload the save after you hack them both. If you did not get one or more of the weapon achievements yet, start a new game on Casual with your power character (from steps 2-5) and finish those off.

Step 6: Bring Down the Sky
To start the mission you need to have gone so far into the story as to be in control of the Normandy SR-1 and be able to dictate were you want to travel. You should then proceed to travel to Asteroid X57 and begin the mission. From here you can explore the new area in the Mako and pick up the other 2 optional missions, or you can proceed with just the main mission. Either way, after completion of the main mission you will have earned yourself a rather easy 50.

Step 7: Beating all mission Records
There are 4 different types of scenarios to choose from, all having 3 stages of advancement, totaling 12 missions that you need to place first position in. The first achievement you will unlock will be for placing first in any scenario, which is "New Sheriff in Town" (Take first place in any combat scenario on Pinnacle Station) and is worth your first 50. Now it is time to place first in all scenarios, which seems more daunting than it actually is. To make this as easy as possible, you should set your difficulty to the easiest setting as doing so will not affect achievements. After you have taken first place in all 12 scenarios you will have earned yourself a further 50.

Step 8: Beating the Admirals Personal Best
After you have beaten and won all 12 of the mission scenarios, you will then be invited by Admiral Ahern to try and beat his own personal best score in a final mission scenario. This will consist of completing objectives and holding out for a period of time. After you have completed this mission, you will be awarded with your final 50.

Step 5: Mopping Up
As a soldier you won't have any special abilities so you will need to create a new character as an Adept and one as an Engineer. Play until you have all their skills unlocked and then work on the 75 uses of each ability, casting them on the transit terminals. AI Hacking is the only one that has to be done on an enemy but it can be done very early against the turrets when you encounter Fist. Same right before that and just reload the save after you hack them both. If you did not get one or more of the weapon achievements yet, start a new game on Casual with your power character (from steps 2-5) and finish those off.

There are 49 achievements with a total of 1200 points

  • Complete 1 Mass Effect Playthrough on any setting

    Finish the main quest. Now, I recommend you start out at Casual. No, Normal is NOT Hardcore, and Veteran is NOT Insane. So, go easy, find out where everything is at. Save your money for the next playthrough. Make sure to always use two allies and do all of the side quests with them.

  • Complete Feros

    Feros is the planet that has the colonists and is not covered in snow. Now, all you have to do is: Talk with the leader, kill the Geth, now this is important: Talk with him again, then talk with the people in charge of: Food, water, and power, and do their side quests! After that, move up the bridge, go to ExoGeni, find Lizbeth, return to the colony. Now, either upgrade your grenades with the Thorian gas or kill them all. Now, if you kill them and didn't do the side quests, you will NEVER complete them.

  • Complete Eden Prime

    This is your first mission. This is important: If you want Insane or Hardcore, you can change the difficulties in-game, but do it BEFORE landing on Eden Prime! This was confirmed in the Bioware Forums. Now, just kill the Geth then de-activate the bombs by standing near them and holding A. After that, approach the Beacon and you're done.

  • Complete Virmire

    Virmire is the planet you receive from the Council. First, you land, clear the AA guns and approach the Salarian Camp. You can get the Charm/Intimidate on Wrex, who will want to get the cure for the Genophage. Don't worry if you don't have it maxed out, there's another chance later in the game. Now, choose between Kaidan and Ashley to go with the Salarians. Later in the battle, you will have to choose who to save. IF one dies and you're doing the romantic sub plot, it will end there.

  • Noveria is the planet covered in Snow, and has Matriach Benezia. In order to get the garage pass you need to help Lorik. Go to the garage, kill the Geth, and drive up. Once in the facility, you'll need to activate the VI's core. Either doing the Tower of Hanoi puzzle [search in the site or google for how to do it] or sacrifice 100 omni gel. Then, activate the power and landlines. Once in the tram, you must kill the Rachni, but first go down the elevator to where the survivors are at, get the pass, and to the hot labs. Activate the Purge and get out. Return to the survivors, (SPOILER: Kill them). Go to the end of the place, and go to the tunnels. Find the Matriarch. To kill her, you MUST kill the Geth and Asari Commandos. DO NOT FIGHT HER. Start off, kill the Asari Command rushing you, then RUN TO THE RIGHT and kill the Geth and Commandos after talking with her, she'll go berserk again. Kill ALL enemies, then kill her.

  • Complete 2 Mass Effect Playthroughs on any setting

    After finishing your Casual, or any play through, select new career and existing ID. Make sure to change the settings in the main menu, difficulty to Hardcore.

    WARNING: Whe you start the game in the Normandy, check the setting again and make sure it is set to Hardcore to get these at the same time! If you land on Eden Prime and it wasn't set right, you will not get the achievement for Hardcore.

  • Complete 1 Mass Effect playthrough on the Hardcore difficulty setting. Do not change the setting.

    ALL organic enemies have immune. They are very accurate and WILL cut you to shreds. Take cover often, but watch out for rockets. Use the Spectre Master Gear and a lot of Biotic powers. Lastly, all enemies are the same level as you.

    Refer to the "Long Service Medal" achievement.

  • Complete 1 Mass Effect playthrough on the Insanity difficulty setting. Do not change the setting.

    Refer to Distinguished Combat Medal and Long Service Medal. Note: ALL organic enemies have immune. They are very accurate and WILL cut you to shreds. Take cover often, but watch out for rockets. Use the Spectre Master Gear and a lot of Biotic powers. Oh, and for fun, enemies and bosses are higher levels than you.

  • Register 150 Pistol Kills

    The pistol is available to all classes and is the easiest one to get if you start working on it right away. No matter your class, put in enough points into the Pistol tree so that you can get the Marksman skill, as it is immensely helpful for this achievement. When you get the skill, use it as often as you can, as it makes using the pistol very effective. Even if you don't play as a Soldier or a class that doesn't have any training for that particular weapon, it is still very possible to get the achievement. Focus on getting as many accuracy improving attachments for the guns you aren't trained in, and stabilizers for Sniper Rifles. It's not as good as playing as a class trained for the weapon, but it's better than nothing. Also, kills made by teammates do not count towards this achievement.

    Note: Sentinels don't have pistol training. They get pistol bonuses from their class skill.

    All weapon kills carry over between playthroughs and careers. Even if you don’t get all 150 kills in one playthrough, any kills you have made will carry over into every other one you may have.

  • Register 150 Shotgun Kills

    See "Pistol Expert" for more info.

    The Shotgun training is only available to Soldiers and Vanguards, but can be done by anyone. Focus on getting as close to enemies as you can, fighting Husks and Thorian Creepers are the best enemies for this achievement, as they need to get in close in order to damage you.

  • Register 150 Assault Rifle Kills

    See "Pistol Expert" for more info.

    Only Soldiers can train to use Assault Rifles, but some of the better ones are viable for use by other classes. Anyone but the Soldier is going to need to focus on improving accuracy if they want to hit enemies, but you must also worry about it overheating. Assault Rifles can overheat very quickly if you don't pay attention, so always make sure it has time to cool down so you don't have to wait.

  • Register 150 Sniper Rifle Kills

    See "Pistol Expert" for more info.

    Soldiers and Infiltrators are the only class that can train in Sniper Rifles, but with enough upgrades, it can become easier for other classes to use them. No matter the class, focus on getting as many stabilizer upgrades for your sniper rifle, so that you aren't moving around much while aiming down the scope. It's still possible for it to stray with upgrades, so you may have to learn how to aim with the movement. It can be a pain, but it is manageable.

  • Use biotic Lift 75 times

    Create an Adept character, as they can use all biotic powers. Go to the Citadel and target a Citadel Rapid Transport station. Use, Lift, Warp, Singularity, Stasis, and Barrier (although you could just run around casting barrier). Then wait for all your powers to recharge and repeat until you get all the achievements. It helps to have adrenaline rush as it resets all your cooldowns, so you can get an extra cast in whenever it is off cooldown.

    Note: Ally power usage will not contribute to these achievements.

  • Use biotic Throw 75 times

    See "Lift Mastery" for more info.

  • Use biotic Warp 75 times

    See "Lift Mastery" for more info.

  • Use biotic Singularity 75 times

    See "Lift Mastery" for more info.

  • Use biotic Barrier 75 times

    See "Lift Mastery" for more info.

  • Use biotic Stasis 75 times

    See "Lift Mastery" for more info.

  • Use Damping Field 75 times

    For these achievements, you'll need to be an engineer class character. To use these: Press RB and highlight the power you want, then press A. You can map it by pressing X, then all you have to do is hit RB to use the power. Only do that if you're working on one at a time.

    To make this faster, use the manual cast for every power you have, then use adrenaline rush. You'll get a second use of every power with that. Now everything will recharge, rinse and repeat.

    YOU must do these, ally casts don't count.

  • Use AI Hacking 75 times

    Must be an engineer.

    The only one of these achievements that MUST be done on an enemy. First, level up to a level 10 and then use all your points on the AI Hacking power. Then you can hack any of the enemies you come across. You will know when an enemy is hacked cause it will attack other foes of yours and will indicate to you it is hacked instead of having an energy bar.

    Just find a turret to use it on... Use it, hide, recharge, rinse and repeat. People have recommended the fight with Fist as a great time to do this with the two turrets in his office. Make a save just before this point, hack them both and reload the save. The hacks will go toward the achievement even though you didn't save your game after doing them.

  • Use Shield Overload 75 times

    Refer to "Damping Specialist".

  • Use Sabotage 75 times

    Refer to "Damping Specialist".

  • Use medi-gel 150 times

    For this achievement, all you will need to do is press the Y button. Make sure you're damaged, or else it won't allow you to use the medi-gel. This carries over play any through. It is likely you'll get it after finishing Hard Core.

  • Use Neural Shock 75 times

    Refer to "Damping Specialist".

  • Find all primary Alien: Council Races, Extinct Races and Non-Council Races codex entries

    This is a missable achievement, but can be done fairly early on, so it's not hard to do in the case you do miss your chance. For this achievement, you must find all codex entries for every race in the game. Getting each codex entry involves investigating certain people while talking to them, which will always be the left option in the conversation circle. Several codex entries can be gained in multiple ways, while others you will only have once chance to get, which is why this achievement is missable. To get each codex entry, you must do as follows:

    Aliens: Council Races
    Asari: Automatically unlocked after first meeting with the Citadel Council about Saren; Talk to Saphyria. She can be found by the embassies, as she is the receptionist. 
    Salarian: Automatically unlocked after first meeting with the Citadel Council about Saren. 
    Turian: Automatically unlocked after the first conversation in the game with Captain Anderson and Nihlus.

    Aliens: Extinct Races
    Protheans (Missable Codex): During the first conversation with Captain Anderson and Nihlus, investigate when given the chance, and Protheans should be one of the choices; After becoming a Spectre, you will be forced to talk with Ambassador Udina and Captain Anderson. After Udina leaves, ask Anderson more about Noveria. 
    Rachni: On the Citadel Presidium, go to the Avina terminal by the giant Krogan monument. Talk with her, and investigate and ask about the Rachni; On Noveria, you can get the codex from two people. The first is Han Olar, the volus scientist. The other is Yaroslev Tartakovsky, who is the last person you must talk to on Noveria. 

    Aliens: Non-Council Races
    Batarian: After officially becoming a Spectre, ask Captain Anderson about his previous mission, while in front of the Normandy. You can also ask him about it anytime you return to the Citadel. He will be in Udina's office at the embassies, on the Presidium; if you chose either the Spacer or Colonist for your Pre-Service history, you will gain a personal quest regarding those backgrounds. Either of these quests will also give you the codex for doing them. 
    Elcor: At the embassies on the Citadel Presidium, talk to Calyn, and ask him about the Elcor; On the Rift Station in Noveria, talk to Petozi. He'll be one of the only Elcor you see on Noveria, so he's not hard to find. 
    Geth: Investigate with Ashley Williams when you first meet her on Eden Prime; Once you get back onto the Normandy after finishing Eden Prime, ask Captain Anderson about it.
    Hanar: On the Citadel Emporium on the Presidium, talk to the Hanar merchant named Delan. Ask him about his speech for the codex. On the other side of the Presidium, talk to the Hanar preaching about the Enkindlers.
    Keepers: By the elevator on the Presidium that leads up to where the council is, there is an Avina terminal and a Keeper nearby. Ask Avina about the Keepers; Talk to the Salarian named Chorban, and accept his quest. He will be scanning a keeper, right in your path when you go to meet the council, so it's very hard to miss him.
    Krogan: Progress through the main story normally. It will unlock when you gain Wrex as a party member. 
    Quarian: Progress through the main story normally. It will unlock when you gain Tali as a party member. 
    Volus: In the embassies on the Citadel Presidium, in the same office as the Elcor ambassador. Talk to a Volus named Din Korlack and ask him about his race; Talk to the Avina terminal just outside of the embassies, and ask her about the Volus.

  • Complete the majority of the game

    By majority of the game, they mean an undefined amount of the game. I recommend that you choose two characters and go with them till the end. Try to not start a side quest without the characters you want. There around 70 side quests including the main quest ones. So, make sure you do around 60 of them before Ilos. IF you haven't gotten the achievement after that, then you should try exploring the galaxy and doing more quests. Remember to talk with allies in order to generate more side quests.

    NOTE! Completing the DLC makes a noticeable contribution toward this achievement. You should be able to earn all of the ally achievements before you get to Ilos if you complete the DLC.

  • Complete playthrough with shield damage greater than health damage

    Simply complete the game with YOU having more shield damage than health damage. Take cover often. This is easiest with a soldier class since they can wear heavy armor. Get a good armor with 4 bars of shield early and this will be simple. Also try to get it on your first play as you will take more damage during your Hardcore/Insane runs.

  • Land on an uncharted world

    A very easy achievement, especially if you plan on getting any of the achievements requiring you to beat the majority of the game. A large amount of the side-quests in the game require you to go to uncharted planets, so you will get this achievement early on. As soon as you land on any uncharted planet, the achievement will unlock. You don't even have to do anything, just land in the Mako.

    Note: Therum, the planet you will find Liara on, does not count towards this achievement. The planet you land on must be optional for the story.

  • Rich



    Exceed 1,000,000 Credits

    This achievement is much easier than it sounds, as money is very abundant in this game. Go through everything you can find pick up as many items as you can, and sell whatever you're not using. Also, doing side-quests also gives you money, so do as many as you can as well.

    When you get this achievement, you gain access to the Spectre weapons, available in the C-Sec surplus store. These are the best weapons in the game, so be sure to buy as many as you can.

  • Register 150 organic enemy kills

    Add the Shredder bullet upgrade to your weapon and allied weapons. Kill anything that is NOT Geth/mechanical. You'll get it eventually. Yes, they carry over to new games. Do side quests. The Cerberus missions have a lot of mercenaries.

  • Register 250 synthetic enemy kills

    Add the Tungsten upgrade to your weapon. By Synthetic, they mean Geth or turrets or anything mechanical. If you don't get this by Virmire, don't worry. The last mission has A LOT of enemies. Do side quests, there are plenty of Geth Ambushes in the beacons.

  • Complete the majority of the game with the Alliance soldier squad member

    See completionist achievement for extra info. This achievement is for Ashley.

    Do A LOT of side quests. Don't worry if you get one ally first and later the other.  You can get two per playthrough only. It is possible to get these achievements even before going to Ilos if you complete every possible side quest and all main missions. Bring Down the Sky DLC will also help.

    Refer to this thread for some insight to these achievements.

    Basic plan of attack for ally achievements:

    • Complete Eden Prime
    • Go to Citadel, talk to Council
    • Find Harkin (Chora's Den), Garrus (Med Clinic) and Wrex (C-Sec)
    • Take care of Fist (do not pick up his OSD!)
    • Rescue Tali in the Wards Access
    • Talk to Council, become Spectre
    • Head to Therum and rescue Liara

    From here, you will have all the allies. Pick the two you want to use and use them for EVERYTHING. If you don't have an ally with decryption and need them to unlock a quest by hacking a computer, switch them in to receive the quest, then immediately go back and switch them out.

    Now with your two allies:

    • Complete any possible Citadel assignment
    • Complete any random space assignments (check this list and see which ones can be acquired simply by visiting a system or planet)
    • Complete Bring Down the Sky missions (400MSP off the marketplace)
    • Complete Noveria (do all assignments BEFORE leaving the arrival site)
    • Complete Feros (do all assignments BEFORE leaving the arrival site)
    • Go back to the Citadel and complete any assignments you started on Noveria/Feros
    • Complete Virmire (do not kill Wrex!)
    • Back to the Citadel once more

    You should have the achievements by now, but if you don't, head to Ilos and finish out the game. Many people got a few of the achievements (mainly Liara) at the very last mission.

    YOU DO NOT HAVE TO DO ANY COLLECTION ASSIGNMENTS FOR THESE ACHIEVEMENTS! -- These missions take forever, and they will help, but they are 100% not required to get ANY of the achievements, even Liara.

  • Complete the majority of the game with the Alliance sentinel squad member

    See "Soldier Ally" for info. This achievement is for Kaiden.

  • Complete the majority of the game with the krogan squad member

    See "Soldier Ally". This achievement is for Wrex.

  • Complete the majority of the game with the turian squad member

    See "Soldier Ally". This achievement is for Garrus.

  • Complete the majority of the game with the quarian squad member

    See "Soldier Ally". This achievement is for Tali.

  • Complete the majority of the game with the asari squad member

    See "Soldier Ally". This achievement is for Liara.

  • Reach 50th level with one character

    Do a lot of side quests. If you do them all, by the first play through you'll probably get to level 40. There is a glitch that only gives you 300xp every time, but to do it: Find Liara when SHE IS TRAPPED IN THE BLUE FIELD! Kill the enemies, save, then load the save. Congrats, you got 300 points! I would only recommend that in the early levels. Also, make sure that when on the Mako to kill enemies on foot, not with the Mako, you'll get more experience that way.

  • Reach 60th level with one character

    You must finish the game once in order to unlock levels 51-60. In total, you will need 862,100 experience points to reach level 60. Do ALL side quests, and it is most likely that you will get this at the end of your second way through or third. Also, make sure that when on the Mako to kill enemies on foot, not with the Mako, you'll get more experience that way.

  • Accumulate 75% of total Renegade points

    See "Paragon".

  • Accumulate 75% of total Paragon points

    On Noveria, when you are given the oppurtunity to accept the assignment from Lorik Qui'in to get the evidence to catch the Salarian (Anoleis, the administrator guy who has his own office) in his rend-based scandal, agree to it. He will open up the shut-down elevator, go down there and get the evidence. Upon exiting to go back to him you will run into Gianna (receptionist lady), so talk to her then go meet her in the hotel/bar. She will ask you to get him to agree into turning Anoleis in, agree and go talk to Lorik Qui'in. Talk to him, and do the following:

    Step 1:

    • (Top Right) Testify against Anoleis
    • (Top Left) {Paragon} You'd be a hero
    • OR
    • (Bottom Left) {Renegade} Damn right I will

    Step 2:

    • Talk to him again
    • (Left) Matriarch Benezia
    • (Bottom Right) Another Question
    • *Repeat step 1*

    Repeat these two steps for whichever one you want until the achievement unlocks, then switch to the other for that achievement. Remember to do whichever way you DON'T want your character to be first so when you finish with the second achievement, you are high in either Paragon or Renegade, depending on your preference.

  • Complete any romance subplot

    Throughout the game, you can talk to all of your squad members and learn about them. Certain squad members, if you talk with them enough, you can eventually romance. Who you can romance depends on the gender you choose to be, but the romance options are as follows.

    Male Shepard: Ashley Williams, Liara T'Soni
    Female Shepard: Kaidan Alenko, Liara T'Soni

    Whoever you decide to romance, make sure you talk with them after every story mission, and always choose paragon or neutral choices so as to keep the romance going. Even after they express interest, nothing will happen until the end of the game. Once you finally are able to go to Illos, your romantic interest will approach you. Continue to be supportive and eventually you will be given the option to invite them in for the night. Once the scene plays out, you will unlock the achievement.

  • Become a Spectre

    This is a part of the story, and cannot be missed. After finishing Eden Prime, you will go back to the Citadel and you must build a case against Saren. Proceed normally until eventually you'll be told of someone who has information against him. When you find the person and meet with the Council afterwards, you will officially become a Spectre, and unlock this achievement.

  • Use Charm or Intimidate to resolve an impossible situation

    There are two "impossible" situations in the game, both of which require you to have very high levels in charm or intimidate. Only focus on one, as putting points in the other is a waste. If you do not have enough, you will not have enough to resolve the situation. Both these decisions are made in the second half of the game, and contain spoilers for those have not made it that far.

    Your first impossible situation is on Virmire, and it involves Wrex. When you find out that the facility Saren is using on the planet is to cure the genophage, and plan to destroy it, Wrex becomes extremely upset. You must talk with him, and try to reason with him as to why the facility must be destroyed. If you have 8 points in either of the alignment skills, you will be able to talk him down from his stance, and he will agree to keep on fighting, which unlocks the achievement.

    The second impossible situation takes place during the finale of the game, on the Citadel. When you finally are able to get to the top of the tower, in the Council Chambers, you will find Saren. After talking with him, you must convince him that he's become indoctrinated, and that there's only one way to end it. Your skills need to be very high to unlock these dialogue options. If you are able to convince him to commit suicide, you will unlock the achievement.

Unlike the other planets, you are not told specifically which planet she is on, only that she is in the Artemis Tau cluster. She is on the planet Therum, in the Knossos star system. The mission starts off with you in the Mako, but after you pass through several gates, must get off and travel on foot, where you will fight a Geth Armature. After the fight, it's just a matter of freeing Liara, and rescuing her. You will then fight against a Krogan sub-boss to complete the mission.
