What you’re going to want to do is to go through each of the three parts of the whole package on at least Recruit first in order to unlock Nightmare for that part as well as to get a feel for the game if you have not already. So now you’ve had your fun or you’ve decided the fun starts here. Otherwise, have a blast! Blast a few demons while you’re at it! Much like many other amazing games of the past, enjoy it! There isn’t much sense in achievement hunting this gem of a game, but if you simply wish to get the Gamerscore and move on, skip ahead to Step Two. In general, this is a solid list with a mix of challenging and simple achievements. This is the same as the 360 release in 2012 with the exception of no online multiplayer.
