Halo who?

There was tremendous hype leading up to developer Infinity Ward's return to the Call of Duty franchise, and it was well deserved. COD 4 is a standard amongst First Person Shooters. It has possibly one of the best single player campaigns I have ever experienced in the genre (rivaled only by Half-life 2) which is wrought with intense game play, and variety of missions. The graphics are amazing, and make you feel a part of the action. The controls are excellent, and smooth, and the multiplayer system is brilliantly setup with the new perks system, and ranking up for new weapons and abilities.

When COD 4 came out, my entire xbox live friends list switched over to the game, and I was hard pressed to find people to play Halo with anymore. COD 4 is a different brand of shooter than Halo 3, offering a more realistic feel of a few shots and your dead... there's very little run and gun type heroics in COD 4, and likens itself more to CounterStrike than Halo. The campaign is short, but lends itself to several play-throughs, and especially trying to conquer it on Veteran, which is extremely challenging.

The only real drawback I found was no co-op mode, and no split screen for online OR system link play. There is a 4 person split screen mode, but no luck on organizing big LAN parties for the game.

I've logged hundreds of hours of gameplay, and haven't gotten sick of it yet, and with new maps being released, and a challenging ranking system on Xbox live, there's plenty to keep the game fresh for a long time.
