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's more Space Marine, so I dig it
Co-Op is fun, but it's a little buggy atm
Don't plan on touching PvP with a 10 foot touching pole though
yea got lots of tyranids
