The fourth multiplayer mode for Resident Evil 6: Siege Mode, has finally released on Xbox 360.

After Predator, Survivors and Onslaught, it was announced another multiplayer mode would be coming to Resident Evil 6.

That multiplayer mode has now landed and can be purchased for 320MSP. Here’s the official blurb.

Protect the innocent civilians from the creatures until the rescue effort arrives. Players can choose to be an agent helping the cilians, or a creature hunting them down in this multiplayer mode that supports up to 6 players!

This video should help explain things a little better.

In addition, a new map pack bundle will be released for 400 MSP. The map pack includes Rail Yard, High Seas Fortress, Catacombs, Requiem for War, Liquid Fire, Rooftop Mission and Creature Workshop.

Also, on March 19 (2o March for EU), a bundle of all four modes (Siege, Survivors, Predator and Onslaught) will hit PS3 for $9.99 / €9.99 / £7.99 (360 owners already have a triple pack for sale, minus Siege).

The Siege Mode can be downloaded right here and comes in at 133.31MB
