For one, you get the Peacekeeper SMG as a new bonus weapon, along with the expected suite of challenges for the weapons and the XP to be gained from completing those challenges. The meat of the DLC is composed of four new maps for online multiplayer play, of course, although I botted-up and ran around them some so I could get a decent look at the maps without constantly being capped unawares. Finally, there is something for the Zombie fans out there - a new location with a new type of gameplay. In Turned, you get to play as a zombie and try catching up to some fast food.
