So Bioware gave us a fourth trophy list. Fortunately, all of the trophies in this list track your progress across the whole trilogy. I'm writing this assuming that each numbered trophy correlates to that number game. So Insanity I and Paramour I both apply to Mass Effect 1. You'll get the kills trophies as you progress through the games. The only one that you kind of need to go out of way for are the melee kills. Don't attempt to grind this in ME1. The melee is terrible.
Walkthrough:
1.0 - Play and Complete Mass Effect 1
See the Mass Effect 1 trophy guide. To do this most efficiently, play on Insanity and make sure to do one of the romances.
Trophies that you'll unlock in this step:
Insanity I
Paramour I
Recruit
2.0 - Play and Complete Mass Effect 2
See the Mass Effect 2 trophy guide. To do this most efficiently, play on Insanity and make sure to do one of the romances. You don't have to romance the same person you did in Mass Effect 1. In fact, you can't. You have to romance someone different. If you don't want to romance someone different, make a back up save before going through the Omega 4 relay. After completing the game, go back and romance someone. You can progress it by doing some of the side missions.
Trophies that you'll unlock in this step:
Insanity II
Paramour II
Soldier
