The Natural Selection Annex (AKA Creature Slaughter Dome]] is another Circle of Slaughter map. It is located to the right of the vendors inside the entrance of the first facility in the Wildlife Exploitation Preserve. It is only reachable if you preordered a copy of Borderlands 2 from Gamestop. If you do not have it installed, you can still enter it if you join the game of a player who has it installed.
