Do you have a Steam account? Why not? Even if you don't have a Steam account, do you like 40k? I was made very happy by my Steam account.
Because in 2011, Space Marine is not just a console shooter.*
It's on PC. And it's available from Steam.
Now, Steam and Relic and 40k are not a natural hit. Really good odds yes, but not a shoe in. On the other hand, Destroy All Humans fairly rocked - the first one at least. THQ has done a very good job of adapting 40k to RTS in both Dawn of Wars.
I know its a long way off, and I haven't seen any game play footage.
But thats an Astartes Heavy Bolter.
Look it up.
*I feared this greatly, following my disappointment that Rockstar was not making a version of Red Dead Redemption for the PC, and noting that the first trailer I saw made no mention of PC on the tail end. The new trailer on Steam clearly has a PC/DVD ROM logo on it.
Bless your weapons.
