Gephyrophobia

Gephyrophobia is a multiplayer level exclusive only to Halo PC and Halo Mac. The level is very similar to the Halo: Combat Evolved campaign level Assault on the Control Room. It consists of a large two-level metal bridge expanding over a misty pit. It was remade as Narrows for Halo 3.

Overview
There is a base on either side of the bridge, one side being red and the other blue. At each side of the bottom level of the bridge are Ghosts. The bridge is similar to those found in the single player level, Assault on the Control Room, but several times larger and wider.

There are three levels in total on this map: the bottom floor of the bridge, the upper floor of the bridge and the two ledges on the side of the canyon overlooking the bridge.

On the lower level of the bridge, there is a Ghost and a Flamethrower at the exit of each base. The middle section of the bridge opens up to reveal a tower, which has an Overshield on the second ledge and a Health Pack on the top. This tower can only be reached by Banshee (There are four on the map). This area is also a popular area for sniping. However, you will have to be on the lookout for other snipers and other Banshees. At the base of this bridge, is a stash of weapons and two Health Packs. On the upper level of the bridge, there is a Health Pack, two Plasma Grenades and two Ghosts near the exit of the base. Towards the middle, the bridge splits into two sides (which forms a ring around the large tower). On either side of the bridge, there are two Shade turrets, a Sniper Rifle and a Powerup. (The powerup is either an Active Camouflage or an Overshield and it depends on which side of the bridge you have taken). It is ill-advised to enter a Shade because they make extraordinarily attractive kills for all players. However, enter it if you wish to take down an incoming Banshee or Warthog.

On the two ledges overlooking the foggy chasm, there are 2 entrances to teleporters leading to and coming from each base. At the exit of each teleporter, there is a Banshee and a Sniper. If sniping, it is advised to do so from here, but take note that there is another sniper at the exit of your enemy's teleporter (as well as a Banshee) which could take you out. Towards the middle of the ledge, there is a Fuel Rod Gun.

In the bases there is an Overshield, Pistol, Shotgun, Assault rifle and a Plasma Rifle. Banshees are very popular, and can usually give you the upper hand on this map. Warthogs are located in front of the base on the top side. Capture the Flag is the best gametype for this map. Race is popular too, due to the large number of vehicles. Individual games like Classic Slayer or Oddball are not popular, because it is difficult to find an enemy.

Trivia

 * "Gephyrophobia" in Greek means fear of bridges.
 * Gephyrophobia is actually larger in size than its successor, Narrows, although it shares many similarities.
 * The energy beams that reside in and out of the bridge, though seemingly just light, are solid and can be climbed.
 * It is possible to land a banshee on the top of the centre support tower. This is an excellent sniping location. This is an excellent tactic to get players stuck on the tower, as if you use a Rocket Launcher, you can blow the banshee off the player used, trapping them on the tower. Forcing them to commit suicide, or wait for someone else to come up with a banshee. This is useful in slayer/team slayer matches, as when the player kills themself, they will lose a point.
