It's not very common for a shooter to be released these days without a form of co-op, but Battlefield: Bad Company 2 is prepared to add such a mode to the mix. Electronic Arts has announced the addition of a co-op mode called "Onslaught" to Bad Company 2 to be released in the near future.

You'll be able to pair up with up to four players simultaneously in "Onslaught." Four existing Bad Company 2 maps -- Valparaiso, Atacama Desert, Isla Inocentes and Nelson Bay -- have been reworked for "Onslaught" with "new lighting, time of day, added vehicles and other effects," according to EA. Every map has a unique, currently unrevealed, reason for requiring teaming up with other players.

"Effective squad play is the key to success in Battlefield: Bad Company 2 multiplayer," said DICE senior producer Patrick Bach in the press release, "and this new mode will provide players with a dedicated environment to test their team skills and rank against the competition.”

"Onslaught" will be distributed over Xbox Live and PlayStation Network (no word yet on the PC version), and EA isn't discussing price or release date for the Bad Company 2 addition just yet.
