In addition to these, there is another human structure that provides three pillars for cover. The only natural "structure" is a rocky, enclosed tunnel. Lots of flora are present, the most prominent being the almost asparagus-like trees and the pink-red ferns. The map has only one side exposed to the nearby ocean, which players may fall into if they are not paying attention or are knocked off. No large vehicles are present, but a small quantity of Mongooses and Ghosts are provided to the players. Aside from Haven, Complex is one of the most popular SWAT maps on the playlist, and is also popular for Capture the Flag and Infection.
