Another interesting question was about the pre-order bonus DLC, Bloodbath Arena. The DLC is like a horde mode with leaderboards. It consists of four different arenas, new weapons, and endless waves of zombies to fight. The idea was to give players a place to take their high level characters and just engage in combat to show off what they can do.There are still some balance tweaks being made to the arena since the team is still trying to decide how much you can bring into the arena from your game and how much you can take out into your main game. For those who don't pre-order from Gamestop, the DLC will be available sometime after launch on Xbox Live and PSN.
