Great game, despite its very brief single-player campaign.

I was a little surprised and taken aback when I finished the single player campaign overnight. I'm not the fastest FPS player in the world, so when I can finish a game in less than 10 hours of game play, that's pretty darn short.

Still, the amazingly immersive storyline that had me almost drying my eyes at the campaign's grand finale, superior production values, the addition of a nice easter egg level/mini-mission after the credits roll, a number of cool achievement ideas, and a very enjoyable multi-player component that adds a nice RPG-light touch to the experience makes this game one of the best shooters on the Xbox 360.

If you don't like multi-player, however, I would recommend you rent it, as it's just too short for a $60 single player title.
