The hilariously bad "drunken" voice acting at the beginning is as cheesy as Nachos Bellgrande (and I just this second figured out that Bellgrande is so named because of Taco BELL - no genius I, at times), but after that it's pretty much straight ass-kicking action, and something I'd totally watch if it were a movie.
Not sure how the player distinguishes friends from foes here, though - more blatant color-coding would be welcome to my tastes. The video apparently features something called Attrition Mode, which is supposedly explained somewhere on their website. You can go look if you like - I'll just be here watching shit blow up real purdy like.
(it's after the jump, of course...)
