Veteran

Kill 2,000 enemies in Mass Effect 1, 2 or 3

You’ll need to complete numerous playthroughs to rack up the 2,000 kills necessary to unlock the Veteran achievement.

You’ll earn this achievement by killing a total of 2,000 enemies across all three Mass Effect games. This will probably take thorough playthroughs of all three Mass Effect games to achieve (perhaps fewer if you complete more than one playthrough of any of these games). If you don’t earn this achievement by the end of your playthrough of Mass Effect 3, you’ll just have to grind out whatever kills you’re missing; pick your favorite game, set the difficulty where you want it, and get to killing.
