So if the three distinct, interwoven story modes, each with its own pair of protagonists for gamers to play as, both online and off, of Capcom's Resident Evil 6 just somehow isn't enough for you, worry not. In addition to the Mercenaries mode, Capcom has three additional multiplayer modes on the way as DLC - Survivors Mode, Predator Mode, and Siege Mode.
As Capcom describes:
Survivors Mode takes the classic solo- and team-based versus mode and adds a twist. Get killed and you respawn as an enemy character with the ability to attack the human characters. Take down two human characters to resurrect in human form. Last man or team standing wins.
In Predator Mode, one player takes on the role of the Ustanak, the fearsome B.O.W. that stalks Jake Muller throughout his campaign, and tries to eliminate the human players. The humans' task: stop the deadly B.O.W. in its tracks, or at least survive until the end of the session.
Choosing the human side in Siege Mode will see players protecting a single NPC, while as a member of the enemy team, players will need to eliminate that same NPC. If the NPC is still alive at the end of the time period, the human team wins.
Survivors, Predator and Siege modes will all support up to six players online and be played using maps from Mercenaries Mode.
All three modes will first be timed exclusives for XBox 360, but will eventually make their way over to PS3 and PC. Resident Evil 6 is out October 2.
