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.
Mass Effect 2:
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 3:
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.
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.
