Perfect Dark Zero (Xbox 360, 2005)

I personally really like this game. For those of you that are very used to Halo 2 there's a little bit of getting used to because the controls are not as fast or as tight for that matter. Also there's very little auto-aim but that's a good thing because it's going to push your skill a little more. The campaign mode is pretty fun, though it's not the best story I've come across. I recommend playing co-op, seems more fun when you have a friend playing with you anyways. The main part of this game has to be the multiplayer. If you got LiVE go on find a game and start fragging. You can go in alone or split screen with some friends. If you don't have LiVE or there aren't enought people online for some reason, you can always add bots (you can adjust their skill level as well) to fill in the gaps. The game has an awesome array of weapons to choose from, pretty much all have a modern design with cool secondary features so most of the weapons are fun to use. If you're an FPS fan you should play this game just for the multiplayer factor :)
