I just got kill.switch for the PS2 and the more I play it the more I realize how much gameplay Gears of War has taken from that game. I'm not saying it's a bad thing, but the mechanics of the two games are very much alike. The main difference is that using cover is a requirement in kill.switch, so if you don't use cover, you will be turned into swiss cheese extremely fast; then it's an option in Gears of War since you have armor that seems to be at least a foot in thickness, kind of like in Unreal Tournament 2003 with the Juggernaut dudes. I really hope that a sequel to kill.switch comes out, because the last one was fun but way too short.
