This page is up to date with the Legendary Edition, by the way, where several DLC armor sets were folded into the main game. Just as with our guide listing the best weapons in Mass Effect 1, 2 & 3, this page is going to be a little complicated - in large part because how armor is treated changes a little between each game in the trilogy. While the Mass Effect Trilogy might have heavy elements of a shooter, all three games are really RPGs at heart - and what is an RPG without a load of loot and character customization to worry about? That's where Armor sets and Armor pieces come in.
