Available as downloadable content, three new gameplay modes will expand on the multiplayer elements available in the retail version and deliver new and exciting ways to enjoy the world of Resident Evil 6. These three modes are called Predator, Siege, and Survivors.
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, you take the role of Ustanak and try to eliminate the other human players. While in turn, the humans have to try and stop Ustanak and/or survive until the end.
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.
While the Press Release doesn’t talk about the exclusivity of this content, other sources are indicating that they are timed Xbox 360 exclusives which means they will come out first on 360 and then later on PS3.
