Capcom confirmed that the first round of downloadable content for Resident Evil 6 is going to be exclusive to Xbox 360 and will arrive on December 18. The pack contains Predator, Survivors and Onslaught modes, with each mode carrying the price of 320 MS Points.

Here's a bit more info:

Available for two to six players, in Predator 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.

Survivors takes the classic solo and team-based versus mode and adds a twist. Get killed and respawn as an enemy character with the ability to attack the human characters. Take down one human character to resurrect in human form. Last man or team standing wins. Survivors can be played by two to six players.

Onslaught sees two players go head-to-head in an attempt to clear waves of oncoming enemies. Chaining combos provides the key to success in Onslaught as this will send enemies over to the opponent's screen, the more that are sent over, the quicker the victory will be.
