Hello again, old friend. It's been too long. Welcome back to the Normandy, Commander. After nearly a decade of rumors and speculation, we finally have a remaster of the Mass Effect trilogy. While this game has the most changes of the three, the trophies are largely the same. They've actually been made easier.
One thing to keep in mind while you're working on these games, there is a separate trophy list for all three games combined. That makes things slightly more complicated. If you intend to complete an Insanity run of Mass Effect 1, the guide is here. You will find helpful tips for each mission as well as videos. That being said, this guide will assume that you're playing through on Casual.
Walkthrough:
[1.0] Complete the game as either an Engineer or an Adept
Play through the game on whichever difficulty that you want and explore as much as you can. The reason that you should playthrough as either an Adept or an Engineer is that quite a few of the missable trophies are for using powers that exclusive to those classes. Hybrid classes like Sentinel or Infiltrator will have some of them, but not all of them. Using one of those classes will let you use the powers of your other squadmates to grind out the remaining trophies. If you played as an Engineer, then take Liara and Wrex with you for their biotic abilities. If you're an Adept, bring Tali and Garrus for their tech abilities.
My preference will be to play as Engineer first, because of AI Hacking Specialist


That list of missable trophies seems like a lot, but most of them you'll need to go out of way to miss. If you zip through the story, ignoring side quests, not using your abilities, and not changing your squadmates, you'll miss almost all of them. They're all easy to unlock though and shouldn't take much trouble.
The one missable trophy to be very careful about is Archivist

Legendary Edition Note: Be sure to romance someone on this playthrough as well. If you're a female Shepherd, you can romance either Kaiden or Liara. If you're a male Shepherd, you can choose from either Ashley or Liara.
Also, play on Insanity for one playthrough. It can be either your first or your second playthrough. It is available to play on from the beginning.

[2.0] Clean Up
