From GameWatcher: “Star Wars Battlefront 2 is gearing up for a very eventful September, as DICE and EA have prepared a number of exciting events for loyal fans and players. The most interesting new release, however, will definitely be the Co-Op mode.
Coming as part of Battlefront 2’s Cooperation Update, this feature will be delivered alongside two all-new game modes: Co-Op and Instant Action, and will be further bolstered by the planet of Felucia and a set of Clone Commando reinforcements.”
