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.

The Sniper Rifle spawns on a bench next to a turret, raised platform, to the right of the main staircase near the spawn area. The Spartan Laser spawns at basically the same position as the Sniper Rifle except to the left of the starting position.

Rockets, SMGs, Frag Grenades and Pistols spawn on the player's side. Look for them on a wall once you leave the building.

Tips

 * It is wise to stay within a short distance of your starting location, largely because players can see approaching enemies at the bottom of the hill long before they are in range.
 * If you are going for the sniper at the very end of the map, be sure to do it early or during a weapon drop. If you are running low on ammo, be sure to have a teammate cover you.
 * The barriers will provide excellent cover from Fuel Rod shots and Wraith mortars, however it doesn't last long.
 * If there is a Wraith annoying you and the rockets and laser are nowhere to be found, the fuel rod makes an excellent alternative.
