DelusionsBeta: FYI it's a Steamworks game, after they tried GfWL for the first game. Since GfWL seems to be going down the pan, and Impulse still hasn't released Reactor, it leaves Steamworks. Que "Steam is PURE EEEEEEEEVIL!".
Despite me not liking DRM, at least this game has co-op and competitive multiplayer, which makes Steamworks a benefit in a lot of ways. It's purely singleplayer games like Fallout New Vegas and Mafia 2 that baffle me as to why they use Steamworks, though DLC is likely the answer.
All in all Steamworks doesn't bother me because I can just crack it if I ever need to. On principle though I disagree with the games as a service thing Steam promotes.
