Call of Duty or battlefield

Definitley Rainbow Six Vegas 2 for campaign and Definitley COD 4 for online.--------------------------------------------------------------------------------------------------------------

Rainbow 6 Vegas 2 definitely. If shooting the bad guys is your style, its for you. Its really good for online too. It has all sorts of awesome features COD4 doesnt have, like hiding behind walls, and customizing your character for both multiplayer and campaign. Its really fun and challenging. Its one of my favorite games, second only to Halo 3. Its by far the best tactical shooter out there. BUY IT!!
