I like Army of Two the way you hide around things & shoot is awesome...Too bad its not splitscreen online with deathmatchs & team deathmatches..More looks for guns would have been nice like camouflage & silver plated guns..

This is too hard to answer. . . but I'd have to say Battlefield for right now, but there are so many great ones, its hard to narrow it down. I'll be playing Haze for the first time tonight (minus the demo) so maybe that will be up there too, but there are so many great ones now, and in the past, its near impossible for me to put just "one'.
