Reviews have been a mixed bag. Seems like a good choice for hardcore WH40K fans, but frankly, there are probably better examples of this style of RTS that already exist. The main draw to this game seems to be the single player campaign. I'm reading a lot about multiplayer being pretty bare bones. Also seeing a lot of reports that the game is poorly optimized. Buyer beware. Maybe worth a purchase on deep discount, but can't be certain it is worth the current $27 pricetag... at least not when there are potentially better alternatives out there.
Well, I'm enjoying it, and I haven't noticed any performance issues at all. But I'll admit it's for Warhammer nerds.
