Volition have today released the second of three planned pieces of downloadable content for Red Faction: Guerilla. This one caters to all the multiplayer fans in the house/on Mars.
No fancy name for this one, it's just the "Multiplayer Pack", and includes two new game modes (Bagman & Team Bagman) along with eight new maps that are playable across all multiplayer modes.
It's 560 MSP on 360, and $US6 on the PSN. The video gives you a decent run-down of some of the new stuff on offer.
