EA have announced that it is bringing co-op mode to Battlefield: Bad Company 2 called Onslaught in which 4 players battle it out against enemies on 4 new maps.
"The new game mode puts you and up to three friends against the enemy on Valparaiso, Atacama Desert, Isla Inocentes and Nelson Bay - redesigned with new lighting, time of day, added vehicles and other effects. Each map has a dedicated gameplay focus, requiring different levels of teamwork in order to complete the objectives against an onslaught of enemy AI. Vehicle warfare comes to the forefront in Atacama Desert while Nelson Bay focuses squarely on infantry assault. Players can compete in squads and check individual progress via the dedicated Onslaught leaderboards."
Senior Producer Patrick Bach had these few words to say about Onslaught mode "We want to consistently support the fans playing the game with new ways to get into multiplayer and also challenge the elite players with new experiences to improve their performance online. Effective squad play is the key to success in Battlefield: Bad Company 2 multiplayer and this new mode will provide players with a dedicated environment to test their team skills and rank against the competition."
Onslaught mode will be available on the Xbox 360 and the PlayStation 3, there has been no mention of a PC version.
