The Mass Effect: Legendary Edition gives fans the perfect excuse to revisit the beloved franchise and play through Commander Shepard’s iconic journey again. Even if you are new to the trilogy, the Legendary Edition packs every piece of content alongside several improvements and enhancements into one neat bundle, allowing you to enjoy the greatest science-fiction story ever told in video games.
For completionists though, it is all about achieving the coveted Platinum achievement/trophy for Mass Effect 1 in a single playthrough. That requires you to know every single missable achievement/trophy in the game, and there are several. This guide ensures that you do not have to reset your playthrough mid-game.

Mass Effect Legendary Edition: The Most Beloved Characters Of The Series
These iconic characters remain some of the most beloved among fans in Mass Effect: Legendary Edition.
Mass Effect 1
has a
missable difficulty achievement
. You must
beat
ME1
on Insanity
without changing the difficulty settings. Make sure to switch your difficulty level before heading to Eden Prime, or else it will not count.
Do not sweat though. Compared to the following two installments,
ME1
is pretty easy.
Missable Character Missions in ME1
You can recruit up to six loyal companions in Mass Effect 1, but only two can join your squad for missions. With nearly a hundred missions, you have plenty of time to switch squad members to unlock all their achievements/trophies in ME1.
While there is a specific mission order where certain allies are suitable for certain missions in light of the storyline, you can take anyone anywhere without worrying about consequences. Sure, your companions will be disgruntled. Some might even be killed depending on your choices, but having a high enough Paragon/Renegade level takes care of that.

Missable DLC Missions
Mass Effect 1: Legendary Edition includes the Bring Down the Sky DLC mission by default. While it is not part of the main storyline, your decisions can slightly impact the narrative of ME2 and ME3. Bring Down the Sky is optional, so you might accidentally miss it. Hence, make sure to complete it before heading to the Ilos planet, which is the point of no return for Mass Effect 1. You cannot return afterwards for the DLC mission.

Colonial Savior |

Complete before going to Ilos. |
Missable Ability Masteries
Apart from a few abilities, all the rest can be completed using Liara and Tali if you are playing as a Soldier class. However, you do not necessarily need to take them on missions for the achievements/trophies because a popular glitch still works in Mass Effect 1: Legendary Edition. The orange Citadel Rapid Transit points on the Citadel (as well as the Mako) are considered a combat target. So, spamming targetable abilities on them counts towards their respective achievements/trophies.

8 Most Fun Exploits In Mass Effect Games
BioWare’s sci-fi franchise has several cool ways for players to get ahead. Here are Mass Effect’s funniest (but also quite useful) exploits.
Other Missable Achievements/Trophies in Mass Effect 1
The Archivist is the only missable achievement/trophy you should be worried about in Mass Effect 1. This is because two of its codex entries can only be unlocked during the prologue section. Hence, if you miss them, you have no choice but to restart the game. These are the Prothean and Geth codex entries. As a rule of thumb, exhaust all dialogues when speaking with someone, especially their “Investigate” dialogue wheel.

The Long Service Medal

ME1

ME2
and
ME3

Can You 100% Mass Effect 1 in a Single Playthrough?
Unlike the original Mass Effect game, you do not need multiple playthroughs to unlock all its achievements and trophies. Thanks to several changes introduced with the Legendary Edition, you can 100-percent Mass Effect 1 in a single playthrough.
This is primarily because the Insanity difficulty is available from the start. You do not need to beat the game once to unlock it. Additionally, achievements/trophies that require you to use certain abilities can now be easily unlocked via squad members during the same playthrough. You just need to know where to invest their skill points.
The only achievement/trophy most players tend to miss is Archivist, which must be partly completed during the prologue, before taking off for Eden Prime. Other than that, you should not have any problem unlocking Platinum for Mass Effect 1 in a single playthrough.
