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.
It looks really cool visually but I can definitely see it getting old without variety. Gears of War kinda understood this, or at least some of those games did. I sort of see Space Marine as similar in style.
