Introduction:
One person is all that stands between humanity and the greatest threat it’s ever faced. Relive the legend of Commander Shepard in the highly acclaimed Mass Effect trilogy with the Mass Effect™ Legendary Edition. Includes single-player base content and over 40 DLC from Mass Effect, Mass Effect 2, and Mass Effect 3 games, including promo weapons, armors, and packs – remastered and optimized for 4K Ultra HD. Experience an amazingly rich and detailed universe where your decisions have profound consequences on the action and the outcome.

Cumulative Achievements:
This achievement list is rather unique in that it has all three games, which have specific achievemnts tied to the game itself, but also has a small set of achievements that either require something to be done in all three games or are cumulative over the course of all three games. To ensure you get the completion, you will want to complete each game with the same character by importing it forward each time, complete each game on Insanity difficulty at least once, and have a romantic relationship in each game (can be with different people each time). Then you'll get achievements for 2000 total kills and 100 total melee kills throughout your career.
 
Personally, I would suggest using a Soldier class character so you have maximum health, defense, and shields to help keep you alive on the difficult Insanity runs. Your companions can be varied to maximize the number of skills you have access to. This should allow you to only do one playthrough of each game. If this is your first time with the series, you may want to play on a lower difficulty first and do a second playthrough for Insanity, but that's up to you. Also, feel free to use whatever class you'd like. The Biotic and Tech skills can be very fun to play with. I'd also suggest using a sniper rifle when possible, then a shotgun if enemies get too close as this can knock many enemies over for easy kills. Be sure to trigger your ally powers to strip away shields and armor before sniping, or use Biotic skills like Lift or Throw that leave them vulnerable for a good period of time to really lay down damage.

Mass Effect:
The completion for this portion of the achievement list is much easier in this release compared to the original. Previously, you'd need to complete 75% of the game with each ally on your squad, requiring multiple playthroughs. Now, you simply need to do five quests with each squad member, which can be done very quickly. You do still need to complete as many missions and assignements as possible for Completionist (75G) but you can use any squad members you like, assuming you've popped each of their "Ally" achievements separately. The Bring Down the Sky "DLC" mission can help with this. Be thorough in completing every side-quest available in a location before moving the story, and switch allies when needed for their achievements.
 
The biggest "missable" I would highlight is the codex entry for the Protheans required for Archivist (20G) very early in the game. Be sure to make the right dialogue choices with Anderson on the ship before going to Eden Prime. If you miss this, it only takes an hour in a new game to get. The other might be for Paramour I (10G), be sure to visit with your crewmates between main missions and work on a relationship with one of them. Oh, and lastly, be sure to put some points into Charm or Intimidate (not both) so you can get Charismatic (15G); there are only two possible locations for this achievement in the game.

Before completing the game, I'd suggest doing the Veteran (25G) and Bruiser (10G) cumulative achievements. There seems to be some trouble with these keeping tracking when moving between games, and both can be done in less than an hour anyway. This may not be an issue on the most patched version of the game, but see those achievements for specifics on an easy grinding method if you'd just like to get it out of the way.

Insanity difficulty for this game is by far the easiest of the three. You generally get equipment upgrades often, your allies have a lot of powers to use, and your weapons can dish out huge damage. Most enemies just become bullet sponges with little to no strategy behind their movements. The only difficult enemies can be the large Geth or Krogan enemies that charge you.

Mass Effect 2:
The completion for this portion of the achievement list is mostly the same as the original releases, though some of the missable achievements from the "DLC" sections have been removed, and the achievements for the Arrival content were removed completely with that being integrated directly into the story. This makes things a bit less stressful and saves a whole bunch of time on the completion.

Your biggest worry here will be the No One Left Behind (75G) achievement for getting through the final mission with no allies dying. Be sure to talk with your squad after every main story mission as you will need to unlock and complete every loyalty mission. You'll also need to completely upgrade the Normandy and make the correct assignments during the suicide mission to ensure everyone survives. Outside of that, you can just run through the story and complete all the combat achievements. The other important thing would be Paramour II (20G) for romancing someone, and ensure you've imported your character/continue playing on Insanity for those cumulative achievements.

Insanity in this game is by far the hardest of the three. You get much less in the way of powers to work with, armor and weapon upgrades are a bit sparse as well, and expensive. You will need to rely heavily on strategy. Place your allies in good spots, use cover liberally, wait until enemy shields/barriers/armor are removed and then use sniper shots to kill weaker enemies. The AI in this game is much smarter, tending to flank you and get you out of your safe zones whenever possible. Take out anyone that is moving toward you first, especially Krogans.

Mass Effect 3:
The biggest change for this part of the achievement list is that the Multiplayer is not present in ME3, which removes a large portion of the achievement list and this really changes how you go about the Master and Commander (50G) achievement. So long as you're completing the rest of the achievements in the game, you should have no issue with this - it's much easier than before. Also, each of the "DLC" sections are dropped to only one achievement, removing all the missable stuff once again, which helps immensely.
 
Once again, be sure to import your character and play on Insanity; once you complete this game you'll finally get Long Service Medal (125G) and Insanity III (100G). And of course get that romance done for Paramour III (50G)! Even though no achievements are tied to it, I'd suggest doing the From Ashes content as soon as possible. The Particle Rifle makes the game so much easier. Aside from that, take note of your combat and upgrading achievements and do those accordingly and you'll have no issues here.

Note: Before completing the game, make sure you upgrade at least the M8 Avenger and M3 Predator weapons to Level 5 (and any others you'd like). This is the max you can do in one playthrough, and we need to get any weapon to Level 10 for the Gunsmith (25G) achievement. We can finish that in about 30 minutes in a NG+ run.

Mass Effect 3 NG+:
Assuming you read the note above and upgraded a couple weapons to Level 5, you can now start a NG+ game on Narrative difficulty and run through the first few missions until you get the Normandy and can use the weapon bench to max out a gun for your final achievement. This should only take about 30 minutes.

Conclusion:
This is an incredible collection of one of my absolute favorite game trilogies. Everything works well, all the updates to the controls and such are very welcome, making the first game feel much better than it originally did, and the achievement list is fairly streamlined compared to before as well. There is still a weighty time investment (depending on how much optional content you do and if you've played the games before), but there are less missables to worry about. With this being added to Xbox Game Pass in early 2022, everyone should certainly dive in if you've never done so before, and people who played before but didn't want to purchase them again have no excuse not to revisit it - except the time investment of course.

Mass Effect Legendary Edition Achievement Guide

Show completed achievements
Show secret achievements

There are 127 achievements with a total of 2915 points

  • Complete Mass Effect 1, 2 or 3 on Insanity without changing difficulty

    See Insanity III (100G) for more info.
  • Complete two games in Mass Effect Legendary Edition on Insanity without changing difficulty

    See Insanity III (100G) for more info.
  • Complete all three games in Mass Effect Legendary Edition on Insanity without changing difficulty

    As the description states, you will need to complete each of the three games in this collection on Insanity difficulty to unlock these achievement. Now, this does not mean you have to do only one playthrough of each specifically on Insanity though. Each game offers a New Game + option so you can play through however you'd like to start and then up the difficulty on a second playthrough if that feels better to you. That said, Insanity is only really difficult in ME2, and even then only in a few specific spots does it really get rough.

    I personally did all three on Insanity from the beginning and played through as a Soldier class. I felt this gave me personally the most survivability and I liked the skills associated with it. This allows you to bring specialized allies (biotic/tech) to round out your squad and you should have a full complement of powers. However, feel free to play as any class you'd like - they are all viable, and you can always bring a soldier-type ally with you if you're playing biotic, and so forth.
  • Establish a romantic relationship in Mass Effect 1, 2 or 3

    For these three achievements, I'll assume you're doing the games in order, so this will focus on Mass Effect 1. To romance an ally, you will want to visit them on the Normandy after each main story mission. You can begin to romance multiple partners by flirting with them and giving them positive dialogue choices. However, at some point you will be confronted by the two parties and be forced to choose one of them. Later on, when you choose to go to Ilos, your romantic interest will approach you and you'll need to accept their advance to have some bedroom time and unlock the achievement.
     
    Male Shep can romance Ashley and Liara.
    Fem Shep can romance Kaiden and Liara.

    If you're romancing Kaiden/Liara, be sure to save them on Virmire. You won't be able to romance someone if you leave them for dead after all.
  • Establish or rekindle a romantic relationship in two games in Mass Effect Legendary Edition

    In Mass Effect 2, romancing an ally remains the same. Visit with them after each main story mission, flirt, and be nice. Once you choose to go through the Omega 4 Relay, you will have the final opportunity to seal the deal.

    Male Shep can romance Miranda, Jack, and Tali.
    Fem Shep can romance Jacob, Thane, and Garrus.
  • Establish or rekindle a romantic relationship in all three games in Mass Effect Legendary Edition

    In Mass Effect 3, romancing an ally continues to remain the same. Visit with them after each main story mission, flirt, and be nice. The one caveat in this game is that with your imported character, you have the option to romance a character you may have slept with in the past. I will write this assuming you have imported a character, but bear in mind you must have romanced that character in ME2 to continue the relationship.

    Male Shep can romance Ashley, Liara, Cortez (new romances) or Tali, Miranda, Jack (rekindle from ME2).
    Fem Shep can romance Kaidan, Liara, and Traynor (new romances) or Garrus (rekindle from ME2).
     
    Be sure if you're trying to rekindle a relationship that you actually romanced that person in the previous game. To be safe, you may just want to go for someone new in each game, but that's up to you.
  • Finish Mass Effect 1, 2 and 3 with the same character

    After creating your character in ME1 and completing the game, be sure to import that character each time you start the next two games in the series. Using that same character for all three games will allow you to bring forward important story choices, receive bonuses from those choices, and of course each this achievement. 
  • Kill 250 enemies in Mass Effect 1, 2 or 3

    See Veteran (25G) for more info.
  • Kill 1,000 enemies in Mass Effect 1, 2 or 3

    See Veteran (25G) for more info.
  • Kill 2,000 enemies in Mass Effect 1, 2 or 3

    This achievement is cumulative across all three games in the series, and tracks any method of kill - gun, melee, power, vehicle, etc. You should have no issue unlocking this naturally. In previous patches of the game, the tracking would reset to zero when you switched between games, but that shouldn't be an issue any longer. If you'd like to be safe, there's a great place to farm this in ME1 anyway. During the mission "UNC: Lost Module" (Attican Beta / Hercules / Eletania) there will be nests of docile monkeys that you can destroy at will. Save in the Mako right in front of one of the buildings, kill all 10 monkeys, reload and repeat. It should only take an hour and then these are out of the way for good.
  • Kill 100 enemies with melee attacks in Mass Effect 1, 2 or 3

    This achievement is cumulative across all three games in the series. To receive credit, the enemy must die from a melee attack. The monkey method I mentioned under Veteran (25G) is great for this as well. Each monkey will die in one hit and do not become hostile at any time, so you can save, kill 10, reload and repeat for a few minutes to unlock.

DLC: Mass Effect

There are 34 achievements with a total of 790 points

  • ME1: Complete the game on any difficulty

    Story related and can not be missed.
  • ME1: Complete the majority of the game

    The "majority" of the game here seems to differ for almost every player. The basic idea is that you will want to complete nearly every possible side-quest (called "assignments") as well as every main quest. It unlocks at different points depending on how thorough you are. Completing the Bring Down the Sky "DLC" missions helps quite a bit toward this as well. Most people report unlocking it with about 16-18 main quests done, and somewhere between 36-42 assigments. 

    There are a large number of assignments that request you to collect a large amount of items - NONE of these are required for this achievement, though they DO count toward the total if you want to do them. Because of the time investment, I wouldn't bother though. You can use this guide to complete every side-quest possible. Try to do everything in a location possible before moving to a new main story quest, as some of these can be missed if you move the story too far.
  • ME1: Complete Eden Prime

    Story related and can not be missed.
  • ME1: Complete Feros

    Story related and can not be missed.
  • ME1: Complete Noveria

    Story related and can not be missed.
  • ME1: Complete Virmire

    Story related and can not be missed.
  • ME1: Complete Ilos

    Story related and can not be missed.
  • ME1: Become a Spectre

    Story related and can not be missed.
  • ME1: Locate Dr. T'soni in the Artemis Tau cluster

    Story related and can not be missed.
  • ME1: Use Charm or Intimidate to resolve an impossible situation

    There are two places you can unlock this achievement during the game, and both require a large number of points in either Charm or Intimidate, so pick one and stick with it for the rest of the game.

    The first chance is at the beginning of the main story mission on Virmire. There will be a confrontation with Wrex, and you need a minimum of 8 points into one of the skills to resolve it. The second chance is at the end of the game on the Citadel when talking with Saren. You need to have 12 points in one of the skills for this opporunity.
  • ME1: Accumulate 75% of total possible Paragon or Renegade points

    You can easily get this naturally by always choosing the same types of answers to questions. Choosing the top answer in conversations will always lead to Paragon points and choosing the bottom answer will always lead to Renegade points. There are also two spots where you can infinitely earn points for this achievement.

    The first chance is on Noveria. During the main mission, you will be sent to speak with Lorik Qui'in. During this conversation, choose "Testify against Anoleis" and then you can either choose "You'd be a hero" for Paragon points or "Damn right I will" for Renegade points. Speak with him again and choose "Matriarch Benezia" and "Another Question" then repeat the first set of choices until you've maxed out one or the other.

    The second chance is during the "UNC: Lost Module" mission. You are sent to acquire something from the monkey aliens in a cave. Collect the module and save your game, then reload. The monkey who previously had it will still be selectable, and you can infinitely spam the action button to rack up Paragon points until you are maxed out.
  • ME1: Complete 5 missions with the Alliance soldier squad member

    This achievement is for having Ashley on your squad. You only need to do five "missions" which include both main story and side-quests (assignments). You should get this at the same time you become a spectre or shortly after while doing Citadel side-missions. Switch her out for Tali, Wrex, or Garrus after to work on their achievements before finalizing your favorite squad.
  • ME1: Complete 5 missions with the Alliance sentinel squad member

    This achievement is for having Kaiden on your squad. You only need to do five "missions" which include both main story and side-quests (assignments). You should get this at the same time you become a spectre or shortly after while doing Citadel side-missions. Switch him out for Tali, Wrex, or Garrus after to work on their achievements before finalizing your favorite squad.
  • ME1: Complete 5 missions with the krogan squad member

    This achievement is for having Wrex on your squad. You only need to do five "missions" which include both main story and side-quests (assignments). You can get this while doing Citadel side-missions or on the first planet after. Switch him out for Tali, Liara, or Garrus after to work on their achievements before finalizing your favorite squad.
  • ME1: Complete 5 missions with the turian squad member

    This achievement is for having Garrus on your squad. You only need to do five "missions" which include both main story and side-quests (assignments). You can get this while doing Citadel side-missions or on the first planet after. Switch him out for Tali, Liara, or Wrex after to work on their achievements before finalizing your favorite squad.
  • ME1: Complete 5 missions with the quarian squad member

    This achievement is for having Tali on your squad. You only need to do five "missions" which include both main story and side-quests (assignments). You can get this while doing Citadel side-missions or on the first planet after. Switch her out for Wrex, Liara, or Garrus after to work on their achievements before finalizing your favorite squad.
  • ME1: Complete 5 missions with the asari squad member

    This achievement is for having Liara on your squad. You only need to do five "missions" which include both main story and side-quests (assignments). She will be the last member you recruit, so you should already have all the other squad ally achievements by then. You can then get this on the next planet you go to before finalizing your favorite squad.
  • ME1: Find all primary Alien: Council Races, Extinct Races and Non-Council Races codex entries

    This achievement is highly missable, though you can unlock it within the first hour or so of the game so it's not the end of the world if you do. The "Protheans" codex entry can only be gained before you leave the ship for the first main story mission, or when talking to Anderson again right after he gives you the ship for good, so ensure you get that. The rest can be unlocked either automatically during the story or through multiple methods, and are not missable. I have only listed the easiest methods which do not expire. The full list of entries for this achievement are as follows:

    Aliens: Council Races
    • Asari: Story related.
    • Salarian: Story related.
    • Turian: Story related.
    Aliens: Extinct Races
    • Protheans: 1) During the first conversation with Captain Anderson and Nihlus, choose "Investigate" before completing the conversation, and Protheans should be one of the choices. 2) After becoming a Spectre, ask Anderson more about Noveria outside the Normandy but before boarding it.
    • Rachni: On the Citadel Presidium, go to the Avina terminal by the giant Krogan monument.
    Aliens: Non-Council Races
    • Batarian: After Captain Anderson about his previous mission. He will be in Udina's office at the embassies on the Presidium after you leave the Citadel for the first time. 
    • Elcor: At the embassies on the Citadel Presidium, talk to Calyn and ask him about the Elcor.
    • Geth: Investigate with Ashley Williams when you first meet her on Eden Prime, or 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.
    • Keepers: On the Presidium, talk to the Avina terminal and a Keeper nearby and ask Avina about the Keepers.
    • Krogan: Story related.
    • Quarian: Story related.
    • Volus: In the embassies on the Citadel Presidium, talk to a Volus named Din Korlack and ask him about his race, or talk to the Avina terminal just outside of the embassies, and ask her about the Volus.
  • ME1: Land on an uncharted world

    See Medal of Exploration III (20G) for more info.
  • ME1: Land on 4 uncharted worlds

    See Medal of Exploration III (20G) for more info.
  • ME1: Land on 8 uncharted worlds

    You will come to many uncharted worlds while doing the game's various side-quests (assignment), and this achievement is actually glitched in your favor as landing on one of those uncharted worlds, returning to the Normandy, and landing back on the same uncharted world increases the counter for this achievement. Repeat that process for whichever planet unlocks Medal of Exploration I (20G) and you'll nab all three of these achievements right away.
  • ME1: Use biotic Lift 25 times

    Lift is a skill that can be used by the Adept, Vanguard, and Sentinal class, or by Liara. To use a skill, hold rb.png and choose it from the wheel for whoever has it unlocked (you may need to invest some skill points to unlock it). This achievement can easily be farmed by targeting a Citadel Rapid Transport terminal. For some reason, people find the most success doing this with the terminal in the C-Sec Atrium location. Otherwise, use it regularly during combat on enemies to unlock it naturally.

    You can combine this with a number of other skills that can be done on the terminals by saving in front of one with all your cooldowns up, using every skill possible, then reloading your save. Progress toward these achievements is saved at the profile level, not tied to the save file, so you can reload the same save 25 times and get any of the applicable achievements out of the way in just a few minutes.
  • ME1: Use biotic Barrier 25 times

    Barrier is a skill that can be used by the Adept, Vanguard, and Sentinal class, or by Liara, Kaiden, and Wrex. To use a skill, hold rb.png and choose it from the wheel for whoever has it unlocked. This achievement can easily be farmed by simply casting the skill - it does not need a target to function. Use it whenever the cooldown is up to get it easily.
  • ME1: Use biotic Throw 25 times

    Throw is a skill that can be used by the Adept, Vanguard, and Sentinal class, or by Liara and Wrex.

  • ME1: Use AI Hacking 25 times

    AI Hacking is a skill that can be used by the Engineer class, or by Tali. To use a skill, hold rb.png and choose it from the wheel for whoever has it unlocked (you may need to invest some skill points to unlock it). This skill is unlocked in the Hacking skill upgrades, and must target a mechanical object such as a turret or a Geth enemy. You will face plenty of Geth during the game, so bring Tali along on missions until this unlocks before you decide to switch her out.

    The quest UNC: Rogue VI has quite a few turrets you can hack for this, so you can make a save prior to entering the buildings, hack everything you see (make sure it says "Hacked" under their name) and then reload your save to repeat this process until it unlocks.
  • ME1: Use Damping Field 25 times

    Damping Field is a skill that can be used by the Engineer and Infiltrator class, or by Garrus and Tali.

  • ME1: Use medi-gel 50 times

    Medi-gel is used by pressing button-y.png at any time. You will get plenty of this throughout the game, so it should come naturally as you progress and get in battles. However, you can easily save with a full stock of it, use it all, then reload your save and repeat to get it out of the way quickly if you'd like.
  • ME1: Use Neural Shock 25 times

    Neural Shock is a skill that can be used by the Engineer and Sentinel class, or by Kaiden. To use a skill, hold rb.png and choose it from the wheel for whoever has it unlocked (you may need to invest some skill points to unlock it). This skill is unlocked by increasing the Medicine skill (where every other achievement has its own specific skill to unlock and improve). This achievement can easily be farmed by targeting the Mako (not the transit terminals like the other skills). 
  • ME1: Complete the Bring Down the Sky mission.

    Bring Down the Sky was a DLC mission added to the original version of Mass Effect, and is available to you once you have access to the Normandy. Travel to Exodus Cluster > Asgard System > Asteroid X57 and land to begin the mission. There are three quests you can complete here which will help toward Completionist (75G) as well as your ally achievements. The only one required for this achievement is "Bring Down the Sky" but be sure to do "Avoid the Blasting Caps" and "Missing Engineers" as well.

DLC: Mass Effect 2

There are 44 achievements with a total of 860 points

  • ME2: Save humanity throughout the galaxy from certain annihilation

    Story related and can not be missed.
  • ME2: Save your crew from an overwhelming attack

  • ME2: Complete the investigation of a derelict alien vessel

  • ME2: Use the Omega 4 Relay

    Story related and can not be missed.
  • ME2: Survive suicide mission

    For this achievement, you must have at least two teammates survive the suicide mission. Since you need the entire team to survive for No One Left Behind (75G), you'll get this as well. See that achievement for more info.
  • ME2: Keep your team alive through the suicide mission

    This achievement requires that every possible team member survive the "suicide mission" at the end of the game. To ensure that this happens, you will first need to complete each person's loyalty mission. There are separate achievements for each of these you can consult if you need any info on those. You also need to upgrade specific parts of the Normandy. Then, during the final assault, you will need to make sure you pick the right person for the right job - and again, you must have completed their loyalty mission for them to succeed and survive. The Normandy upgrades and acceptable job choices are below.

    Normandy Upgrades:
    • Silas Armor
    • Cyclonic Shield
    • Thanix Cannon
    Squad Jobs:
    • Vent Specialist: Tali, Legion, Kasumi
    • Fireteam Leaders: Miranda, Jacob, Garrus
    • Biotic Specialist: Jack, Samara, Morinth
    • Second Fireteam Leader: Miranda, Jacob, Garrus
    • Crew Escort: Anyone loyal (Mordin)
    • Hold the Line: Grunt, Zaeed
    • Final Squad: Anyone loyal (Zaeed, Thane)
    I put in bold which specific choices I made when I unlocked the achievement.
     
    It's worth noting that crew members dying does NOT void this achievement. It is entirely dependent on your recruited teammates. To save as many crew members as possible, you will want to make sure you don't do many missions after recruiting Legion. The best option is to do every assignment, loyalty mission, and main story quest up to the point you need to recruit Legion, then immediately do his loyalty quest after that mission, and then move into the final story quests. Again, saving the crew is optional though.
  • ME2: Obtain geth technology

    After completing the main story mission "Acquire Reaper IFF" you will have a choice back on the ship if you trust Legion or not. Be sure to accept him onto your crew to have him as a teammate and unlock the achievement.
  • ME2: Successfully recruit Archangel

    Story related and can not be missed.
  • ME2: Successfully recruit the Assassin

    Story related and can not be missed.
  • ME2: Successfully recruit the biotic Convict

  • ME2: Gain the loyalty of the Cerberus Operative

    See Broke, Blind, and Bedlam (15G) for more info.
  • ME2: Gain the loyalty of the Professor

    See Broke, Blind, and Bedlam (15G) for more info.
  • ME2: Gain the loyalty of the Cerberus Officer

    See Broke, Blind, and Bedlam (15G) for more info.
  • ME2: Gain the loyalty of the quarian

    See Broke, Blind, and Bedlam (15G) for more info.
  • ME2: Thresher Maw defeated

    During Grunt's loyalty mission, you will face off with this giant monster. You will have a five minute timer to kill it before it disappears, so be sure to put everything you've got into it. If you're on Insanity difficulty, it can be quite a bullet sponge. However, it only has an armor bar, so using a Soldier with Inferno ammo makes it fairly easy. Bring Mordin for his Incinerate skill too. The Collector Paticle Beam weapon found on Horizon at the beginning of the game is great against it as well. 
  • ME2: Perform 30 headshot kills with any weapon on humanoid targets

    If you're using a sniper rifle or heavy pistol this should come fairly naturally. In the beginning of the game, you can do this against the robots that attack during the tutorial with Jacon on requesting allies use their powers. Don't trigger his Pull ability and just keep killing the robots. They count as humanoid and you can farm the achievement there, reloading when you run out of ammo.
  • ME2: Incinerate the armor of 25 enemies

    Mordin will be your friend for this achievement if you don't have it on your created character. Use his Incinerate ability to strip away the last of any yellow armor bar to get credit toward this achievement. Husk enemies are great for this as an upgraded Incinerate will usually strip away their entire bar in one shot since they have low health. The mission "N7: Abandoned Mine" has a ton of them. Save before enterine the mine and kill everyone, then reload if you didn't get it to repeat the process.
  • ME2: Make 20 enemies scream as they fall or are set on fire

    This is easy to get if you're using a Soldier class with Inferno ammo, you'll set nearly everyone on fire. If not, use Biotic powers such as Pull when enemies are near ledges so they fall off. Asking your squad to use powers still counts as well.
  • ME2: Disrupt the shields of 25 enemies

    Overload is the ability you'll need here. If you don't have it on your created character, use Miranda, Garrus, or Kasumi in your squad. You will need to deal the finishing blow to someone's blue shield bar with this ability. There are copius amounts of chances for this in the game, most notably during Garrus' loyalty mission or very early in the game there will be multiple turrets to destroy where you can reload and get five at a time. You can save before a large fight and reload to farm the same enemies if you need.
  • ME2: Hit 20 different targets with multiple biotic powers to combine the effects

    This achievement is a bit finnicky. The most consistent way it seems to get counted is by using two different characters to use their powers on an enemy with no shields or armor, just their red health bar. Have one character use Pull, then the next one use Warp or Slam. The mission "N7: Lost Operative" has two such enemies directly at the start. Save before entering the door, then use the combo on both, and relead to repeat.
  • ME2: Warp the barriers of 25 enemies

    Barriers are purple bars above an enemy's health. Most Asari enemies will have barriers. You must remove the last portion of a barrier bar using the Warp ability for credit toward this achievement. Warp can be learned by Miranda, Thane, and Liara if your created character does not have it. If you save prior to a fight some a few biotic enemies, you can warp their shields, then reload and farm them this way until the achievement unlocks.

    ME2: Complete 5 missions discovered by scanning unexplored worlds

    There are a number of missions that will count toward this achievement, and a full list can be found HERE. Go to the specific location and scan the planet to find a beacon, then land to complete the mission.
  • ME2: Visit 100% of the planets in an unexplored cluster

    There are a number of clusters that can work for this. To raise the percentage of exploration, you simply need to enter the orbit of a planet in the cluster, and repeat for each planet. After recruiting Garrus, Mordin, and Grunt, you'll have access to the Shadow Sea cluster which only has four planets to explore making this one of the quickest by far.
  • ME2: Complete a mission discovered by scanning an unexplored world

    See Agent (25G) for more info.
  • ME2: Complete any research project in the Normandy's laboratory

    After recruiting Mordin, speak with him on the Normandy to see a list of upgrades you can purchase. You will need materials found in lootable crates during missions or found by scanning planets. Once you have enough resources, purchase any upgrade to unlock this achievement.
  • ME2: Fully upgrade a weapon

    Weapons will generally have 7-9 upgrades available for damage and extra bonuses. You can either find these during missions, get them as rewards, or purchase them from Mordin. You can see a full list of available upgrades for each weapon and how to obtain them HERE. Once you have every upgrade for one weapon type, this achievement will unlock.
  • ME2: Unlock 15 new Mass Effect 2 codex entries

    This should unlock naturally just through the story. You will get many new codex entries when taking on new missions and speaking with new characters, and you'll get plenty through the side-quests and loyalty missions as well.
  • ME2: Evolve any power

    You need at least 10 skill points to unlock this achievement. Once you purchase Level 4 of a skill to max it out, it will evolve and you will pick a specialization for it. Do this with any one skill to unlock the achievement.
  • ME2: Gain the loyalty of the mercenary

    See Broke, Blind, and Bedlam (15G) for more info.
  • ME2: Gain the loyalty of the thief

    Each character you can recruit to your squad has an accompanying Loyalty Mission to complete. Each main story mission you complete should trigger someone's loyalty mission to become available, and Kelly Chambers will alert you that someone wants to speak with you. Do so to trigger their mission to start, and I'd suggest completing them right away.
     
    For the most part, you simply need to complete these missions to earn their loyalty (which gives them a bonus power and helps toward their survival in the suicide mission), but a few people have choices during the mission that can make the mission fail, permanently losing their loyalty. There are also two instances where you will complete a pair of loyalty missions and then the two crew members will get in an argument. You will need to resolve this situation using Paragon/Renegade options to ensure that both members stay loyal. If you side with one over the other, you'll lose someone's loyalty.

    For a full guide on these missions, the fail conditions of the four missions I mentioned previously, and the two instances where you'll need to resolve disputes, see HERE.
  • ME2: Successfully shut down the rogue VI in Project Overlord

    Project Overlord is a four-part quest that can be started at any time after acquiring the Normandy. It's a tough mission, so leaving it off until later in the game when you have stronger squadmates and more powers would be a good idea though. You can find a walkthrough for the mission HERE.
  • ME2: Confront the Shadow Broker

    This quest can be done any time after meeting Liara on Illium. Once you obtain the quest, simply complete it to unlock this achievement. There is nothing else special to do in the content achievement-wise, so just finish it up for the achievement. A walkthrough can be found HERE.

  • ME3: Stop a Cerberus kidnapping

    After the main mission "Priority: Palaven" speak to Traynor to unlock this quest. You must do this pretty much immediately or you will fail it and not be able to unlock the achievement. Doing three missions after acquiring it will result in automatic failure. You can find a walkthrough for this mission HERE.
  • ME3: Evacuate a scientific facility

    After the main quest "Priority: Citadel II" speak to Traynor to acquire this quest. A walkthrough for this quest can be found HERE.

    ME3: Mission accomplished

    Story related and can not be missed.
  • ME3: Visit a store on the Citadel

    Your first chance at this achievement will be on the Citadel. You can find Sirta Supplies near the reception desk.
  • ME3: Deliver most of the Galaxy at War assets to the final conflict

    This achievement is a little weird in the Legendary Edition because the Multiplayer portion was left out, and it highly influenced how this was calaculated on Xbox 360. In this version, it still appears as if the game counts your war assets as if the MP still did exist. Your goal should be to have a score of 5600 in war assets after completing a Priority mission. For instance, if you begin "Priority: Rannoch" with 5400, it will unlock after that mission when you speak with Admiral Hackett since you'll gain a large number of assets from that mission. This mission is where most people report it unlocking, and believed to be the earliest you can earn the achievement.

    Assuming you are completing as much side-content as possible (which is required for the completion), you will get this with little issue. You'll also get extra bonuses throughout the game for completing the first two games, which I'll assume you're doing since they're all included in one achievement list.
  • ME3: Dispatch 10 probes to retrieve people or resources in Reaper territory

    There are a large number of locations that work for this achievement. A comprehensive list with pictures of the planets and the exact resources you can obtain can be found HERE. Once you reach a planet that has materials, hold lt.png to scan and follow the white line until a white circle shows up. Press rt.png inside that circle to launch the probe and retrieve the assets.
  • ME3: Modify a weapon

    On the loadout screen before each mission or on the Nomandy, you can edit your weapons by pressing button-x.png and if you have a mod that can be installed you will choose it there. Once you have successfully installed a mod the achievement will unlock.
  • ME3: Perform any combination of 50 biotic combos or tech bursts

    There are a large number of combos that should work for this achievement, but it is notoriously finnicky. Essentially, you or a squadmate must use one power and while that power is still active on the enemy, yourself or a second squadmate must then use a second power on the same enemy. If an enemy is floating in the air because of Pull and you then Throw them, this should count and you should see an explosion to indicate so. Many of these should happen naturally as your allies use powers, but be sure to initiate it whenever possible. You can always save before fighting an enemy that is in a good spot to do a combo and reload/repeat against them to farm it out if necessary. The full list of combos can be found below.

    Biotic Explosion
    Singularity > Warp
    Singularity > Throw
    Singularity > Biotic Charge
    Singularity > Nova
    Singularity > Cluster Grenades
    Singularity > Shockwave
    Warp > Shockwave
    Warp > Throw
    Warp > Biotic Charge
    Warp > Nova
    Warp > Incinerate
    Warp > Cluster Grenades
    Stasis > Warp
    Stasis > Shockwave
    Stasis > Throw
    Stasis > Biotic Charge
    Stasis > Nova
    Stasis > Cluster Grenades
    Pull > Shockwave
    Pull > Throw
    Pull > Biotic Charge
    Pull > Nova
    Pull > Cluster Grenades

    Tech Burst
    Incinerate > Overload
    Incinerate > Throw
    Incinerate > Warp
    Incinerate > Carnage
    Cryo Blast > Incinerate
    Overload > Warp
    Overload > Biotic Charge
    Overload > Concussive shot
    Overload > Incinerate
    Carnage > Warp
  • ME3: Evolve any of your powers to rank 6

    You will need a total of 21 skill points to assign into one skill to reach Rank 6. If you import your character from ME2, which obviously we should be if we're going for the completion, you will be able to do this right away. Otherwise, once you level up enough this should come naturally as you assign skill points.
  • ME3: Escape a Reaper in the galaxy map

    For this achievement, you will want to enter a Reaper-controlled area (you'll see their ship over the system you enter). When you are inside the system, use lt.png to scan and once the Reaper Alterness bar is filled, a Reaper will appear and chase you. You need to escape through a Mass Relay once the Reaper appears to unlock this achievement. So long as you are scanning near the relay, it should be extremely easy to get to it and escape the system.
  • ME3: Overload the shields of 100 enemies

    If you don't have this ability on your created character, Garrus and EDI will be your friends here. Use the Overload ability on enemies with a blue shield bar 100 times to unlock this achievement.
  • ME3: Lift 100 enemies off the ground with powers

    You should be able to get this achievement no matter what class you choose. Supposedly, squad powers should count, but most people report they do not seem to move the tracker. I personally got it as a Soldier with Concussive Shot. Any power that lifts someone off their feet should apply, except Slam for some reason. The full list that appears to work is: Throw, Pull, Biotic Charge, Concussive Shot, Flare, Lash, and Singularity.
  • ME3: Set 100 enemies on fire with powers

    This achievement will work with any fire-based power, including Incindiary Ammo or Inferno Grenades which should be the easiest. You can also use Incinerate as well.
  • ME3: Kill a brute while it's charging you

    Brute enemies will first be encountered on Palavan. These enemies will run headlong at you and do massive damage. You need to kill them while they are doing this type of charge to unlock the achievement. You can either get this normally, but wearing down the enemy and getting its health bar down to one chunk before the charge, then unloading a full clip of ammo or you can use the "Reaper Blackstar" weapon which can be found after fighting the second Brute. Shortly after that, two more Brutes will attack at once. The Blackstar should kill them in one shot, even on Insanity. Another great spot for this is in the Leviathan "DLC" mission, as you'll be in a mech suit when fighting the Brutes.
  • ME3: Kill 10 guardians with headshots from the front while their shields are raised

    Guardians are the enemy you'll be looking for to get this achievement. They will have a large shield blocking their entire body, but there will be a long slit near their eyes that you can shoot through. The Particle Rifle you get in the From Ashes "DLC" content is great for this, and any sniper rifle works perfectly as well.
  • ME3: Hijack an Atlas mech

    To hijack a mech, you first need to take out the blue shield bar any way you'd like. After that, exclusively target the front glass area to break it so you can shoot the pilot directly and kill them before the mech explodes. After that, you should be able to approach the mech and enter it, unlocking the achievement. You can find mechs in the following missions: Grissom Academy: Emergency Evacuation, Priority: Eden Prime, Tuchanka: Bomb, Priority: The Citadel II, Arrae: Ex-Cerberus Scientists, Omega: Aria T'Loak, and Citadel Archives: Escape.
  • ME3: Defeat a harvester

    Story related and can not be missed.
  • ME3: Obtain two non-customizable suits of armor

    You will need to purchase at least two different sets of armor for this achievement. The following armor sets from stores on the Citadel will count:
     
    • Blood Dragon Armor (Hanar Store)
    • Inferno Armor (Kassa Fabrications)
    • Collector Armor (Nos Astra Sporting Goods)
    • Terminus Assault Armor (Batarian State Arms)
    • Cerberus Armor (Elkoss Combine Arsenal Supplies)
  • ME3: Upgrade any weapon to level 10

    EA did a surprisingly great job updating the achievements in this collection to be more user-friendly, and then they dropped the ball considerably with this one. Unfortunately, you will need a short NG+ run to complete this, as you can only get to Level 5 in upgrading any weapons in your first play of the game. Make sure you max out at least the M8 Avenger and M3 Predator, but do a few other guns to be safe, as it appears different classes can only max out certain weapons.
     
    Once you have your weapons maxed in your first playthrough, begin a second run and go ahead and drop your difficulty to Narrative. Run through the first few missions until you have access to the Normandy again, and use the workbench to upgrade one of your weapons to Level 10 to unlock the achievement.
  • ME3: Uncover an ancient secret

    This achievement is for completing the Leviathan "DLC" story mission. You can access this anytime after "Priority: Palaven" and should get a message on your terminal from Admiral Hackett to initiate the mission. Simply completing the story quest will unlock the achievement.
  • Savior

    ME3: Free Omega from Cerberus Occupation

    This achievement is for completing the Omega "DLC" story mission. You can access this anytime after "Priority: Palaven" and will get the quest from Aria T'Loak in Purgatory (on the Citadel). Simply completing the story quest will unlock the achievement.
  • ME3: Stop an out-of-control scheme before it's too late

    This achievement is for completing the Citadel "DLC" story mission. After the main story mission "Priority: Citadel II" you should receive a message on your terminal from Admiral Hackett to initiate this mission. Simply completing the story quest will unlock the achievement.
  • ME3: Defeat a group of Spectre-level opponents on Normal, Hardcore, or Insanity

    This achievement can be quite difficult, but thankfully there is a cheese method you can use. First thing you'll need to do is wait until you have access to the combat sim in the Silversun Strip. Then you need to unlock Spectre opponents. Complete Arena matches on Narrative difficulty until you earn a few silver medals. Now purchase some combat multipliers (weak shields, no medkits, and no ammo crates are great) and Geth enemies to fight. Do a match with those settings and aim for a gold score, which will allow you to purchase Spectre enemies.
     
    Turn off all the multipliers (we don't care about our score at this point) and start a match against Spectre opponents, but leave the difficulty on Narrative for now. Defeat the first two waves and all but one enemy in the third wave, then pause your game and up the difficulty to Normal. Defeat the last enemy to unlock the achievement.
     
    Warning: Be sure to do this on a different save file than the one you're using to get the Insanity achievements!
