Risk Faction is now available on Steam for a decent USD$9.99. The game itself has been out for a while now on Xbox Live Arcade and the PlayStation Network, but finally knocks on the PC's door to ask for a belated sleep-over, and about time, too.
For fans of the physical board game of Risk, there's a version of the classic game tucked into the product, but we urge you to check out the beefed up campaign from Stainless Games, as it's colourful and quite deep in terms of its strategy and what it does with the original game's rules to bring it up to modern speed, so to speak (in that it's faster to play).
