The "first wave" of DLC for Resident Evil 6 will be available on Xbox 360 on December 18th. As announced months ago, the DLC will be a timed exclusive on Xbox Live, and should arrive on PS3 in the future.

Three new multiplayer modes will be available for Capcom's zombie shooter: Predator, Survivors, and Onslaught. Each will be available for 320 Microsoft Points ($4), or bundled together for 720 Microsoft Points ($9).

Here's how Capcom describes each of the three modes:

Predator - 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 - 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 - 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.
