Security Zone

Security Zone is a Firefight map in Halo 3: ODST, based on the campaign level ONI Alpha Site, set in the city of New Mombasa. It takes place near an Office of Naval Intelligence complex in the city, and is described as a medium-sized map, with sniper rifles and turrets situated high up, with a central valley for the purpose of funnelling enemies. Midway through a Firefight game on this map, Wraiths will spawn, though hijacking them has been disabled on this map for balance reasons.
