Description:Fight in the interior of the ONI headquarters
Complete the mission ONI Alpha Site in Campaign to obtain this map in Firefight
Alpha Site is a medium to large Firefight map. The interior consists of two half-diamond shapes that hold the spawn points as well as a health pack each. Below this are two smaller half-diamonds, which are staircases leading down to the main floor. Each of these staircases has a niche to the side which holds a health pack, pistol ammo, smg ammo, and fragmentation grenades.
The main area is roughly a large square between these half-diamonds. It is largely open, with several boxes and crates, as well as an open elevator against the outter wall. Leading from here are two paths to the outer courtyards, which is where the Covenant drop.
This map is thought by many to be one of the easiest Firefight maps. The covenant come through only two access points out on the balcony, allowing playes to hole up in each of the interior corridors and not worry about anything behind them. This, combined with an arsenal of rockets, sniper rifle, and shotgun, give players a rather effective corridor to cause massive destruction in.
Bonus Round-Bonus rounds in Alpha Site consist, as usual, of a mass of Grunts swarming the players. Instead of droppin out on the landings like the normal waves, the Grunts drop from above the three elevators in the center of the map.

In Alpha Site, there are:
~Four health packs (denoted by yellow health symbols on map)
-One each in each spawn area, one each beside the staircase under each spawn area
~Four each of SMG and pistol ammo
-Two each beside the staircases on either interior side (denoted by smg symbols, standing for two each)
~One sniper rifle
-Central pole between each of the spawn areas, located on the west side
-ammo is on a bench on the right balcony, as denoted by a red sniper symbol
~One shotgun
-Central pole between each of the spawn areas, located on the north side
~One Rocket Launcher
-Central area between both of the outer terraces, located on the wall above a bench.
-ammo is on a bench out on the left balcony where phantoms drop covenant, as denoted by the red rocket symbol
Four Player Strategies
Submitted by MBT Boomer MBT
This strategy is the same for ALL DIFFICULTIES.(Four person/player strategy)
Right off, STAY AT THE SPAWN, don't go down the stairs at the spawn, you'll be susceptible to everything. Since two players spawn at either side, don't go to the other side unless it is needed. In the case of the two stronger players being on one side and the two weaker ones being on the other, it is recommended that one person from each side switches.
Sniper Side:
For the two players on the Sniper side, DON'T GRAB THE SNIPER UNTIL WAVE THREE, you'll waste the ammo if you don't wait. The other player needs to make sure they are stocked on Pistol and SMG ammo, as they will be protecting the Sniper. At the start of the wave, the non-sniper should be using the pistol to take out Grunts and Jackals with head shots. The Sniper should be focusing on bigger targets like Hunters and Brutes. And remember, stay on the Spawn Stairs.
Shotgun Side:
This side is basically the same as Sniper side, except that the shotgun should only be grabbed if one person has no ammo and the ammo boxes are empty. After each round however, one person from this side needs to rush and get the newly spawned Rockets so they can easily take out Hunters and Chieftains.
Between Waves, Rounds, and Sets: This is the ONLY time you should EVER go to the middleto pick u any needed ammo.
Black-eyes Effect on the Strategy:
OK, So Black eye sucks right, well, with this strategy, most of the enemies are forced to come to you, so when they get to the stairs rush and beat them down, but quickly retreat back up because you can get hit back real easily.
Chieftain Round:
Yes, we all know what Chieftain round is, it is the last wave of every round. During Chieftain Round again, Stay at the spawn, they WILL come to you,when there is one Chieftain left it is OK to work as a team (all four players) to take it down fast and smoothly, this is one special time you may leave the stairs.
Bonus Round: During This Round, once you get the necessary points, have fun, you wont lose lives or points, this is the happy round, although, it can be ended quickly due to the lose quarters style. and yes, they drop from the ceiling.
Alright, this strategy is golden and should let you get up to Set five in about 2 and a half hours, if you just STAY ON THE SPAWN STAIRS
