Just picked it up today on Steam and played it for about 30 mins tonight, pretty damn fun so far. I'm a big fan of the Warhammer 40,000 books and this game does a pretty good job so far of relating to them.
Anyway, it plays real smooth at 1600/900 with all of the options maxed out on my Vaio. This thing never ceases to amaze me for a laptop. There is a Demo available on Steam, worth the DL for sure.
