Today's hottest video again hails from the rocky peaks of GameTrailers; a trailer for Army of Two is that site's most watched file. This action-shooter's video shows a single army (of two) engaging a variety of enemy situations.
Apparently berating your teammate and slapping him is a situation for which two-person armies are trained. (Didn't they watch Patton?) At least we also see the cooperative moments -- partly offsetting these in-your-face-to-the-extreme antics -- like when one soldier drags his injured buddy away from the fire-fight.
