To me, it's probably Zombie Apocalypse. It's not my favorite gun, but it has the best "feel" for me. It just feels exactly like what it does. It's probably even enjoyable to waste all the clips shooting at the sky. and agreed, gunplay is very well done in this game. Story, content, options and such are lacking in every way, but shooting feels good. Everything you see in the screen action-wise translates so well to the controls and vibration. edit: oh yeah, and Praedyth's Revenge. I suck with snipers, but that one just feels so right in every way.
