DICE has announced a new, four-player co-op pursuit for Battlefield: Bad Company called Onslaught mode.
This is "coming soon" to PlayStation Network and Xbox Live Marketplace. The content will be paid for, according to a post by DICE associate producer "Bazajaytee" on the EA forums. He didn't say how much, simply answering "nope" when asked if the content would be free.
Onslaught mode will not be available on PC. "We aren't ruling out Onslaught on PC, but at this time we are researching how to bring it to PC without affecting players who don't have Onslaught or their own server to run it on," said Bazajaytee. "We haven't given up on a PC version of Onslaught as I say, just we have a lot things to work out first."
Onslaught mode is for up to four players. To begin with, there will be four maps to play: Valparaiso, Atacama Desert, Isla Innocentes and Nelson Bay. They've been redesigned with new lighting, time of day, more vehicles and other touches.
Each map has a different focus. Atacama pushes vehicular combat to the fore while Nelson Bay concentrates on infantry. Onslaught will have leaderboards for squads to compete on.
