fitgirl has it. gameplay feels kinda dated, but with some nice additions. Looks pretty good, and the horde engine is cool, lots of baddies to shoot. Unless the pvp and online coop modes are amazing, I can't imagine it being worth 60$, but for the price of free, i'm digging it.
Idk why the fuck I'd play a Space Marine game without enemies with faux cockney accents yelling "SPEHS MUHREEN!?". Can a tyranid yell with a faux cockney accent?
