Risk: Factions, to Facebook this summer. The title will feature the same competitive multiplayer components of its XBLA, PSN and PC counterpart, and will add "special weapons" to help distinguish each of the different factions therein. For instance, humans will have an ability that boosts their attack, while zombies have a weapon which makes them "better brain-eaters." (Sharper teeth, we guess?)
Risk: Factions is currently in closed beta, meaning we should find out how these new special abilities influence the game's tightly-balanced strategy soon enough. All the tactics in the world can't overcome razor-sharp zombie molars, you know?
