Description: In the “Bloodbath Arena” DLC four different arenas offer new challenges that can be played alone or in coop mode. It’s a desperate fight for survival where waves after waves of unrelenting zombies attack, one more gruesome than the next! In this DLC characters can loot experience points and items and bring them over to the campaign mode. Players can show off their skills in zombie fighting with the newly implemented leaderboards. The brain wave bomb, a new exclusive weapon, tops this DLC package off.
