In 2009's Red Faction: Guerrilla, Volition was able to incorporate some of the single-player campaign's heralded "emergent gameplay" -- the spontaneous entertainment of bringing down the gameworld's structures in fantastic, inventive ways -- into the game's competitive multiplayer. A wall you thought was suitable cover could suddenly come crumbling down, revealing a charging Martian opponent about to clobber you with a deadly ostrich.

The fragility of the gameworld added an element of tension; that you wielded the powerful and inventive abilities and weaponry that made it so fragile was just plain cool. Guerrilla's multiplayer seemed like a first step toward greatness -- a foundation that Volition could build into one of the truly great online experiences.

That's all on hold, however, as Volition's next Red Faction game, this May's Armageddon, won't have competitive multiplayer. In its place is "Infestation," a retread of Gears of War 2's often aped Horde mode.
