Extraction’s closed beta will kick-off in October, Splash Damage and Nexon America have announced. Originally known as “Dirty Bomb”, the closed beta for the online multiplayer shooter will have limited openings, so only a select number of players will be able to participate. Notifications will be sent to chosen players by October 1, when the closed beta period begins. Testers will be helping out with stability and balancing. Significant contributions have already been made to the game by its alpha testers since December 2012. Sign up for closed beta testing here.
