Rat Race

2-6 players

Summary
Rat Race is a multiplayer map in Halo: Combat Evolved. It is a circular map, with a multitude of Teleporters, tunnels, and passages.

The most notable feature of the map is the central section of elevated tunnels. There are two entrances to this complex, one by way of teleporter and one by way of an inclined ramp. The strategic value lies in the two exit points, which allow a player to drop unexpectedly from the ceiling through a wide hole into the enemy section of the base. Since this is strictly a one-way vector of attack, and jumping down this hole usually entails grabbing an active camouflage or overshield powerup, defenders are forced to keep an eye to the ceiling.

Rat Race is similar to the map on Halo 3 named Rat's Nest and has the similar name and "race" map.

Glitches
The main glitch in this particular level is dropping both the overshield and active camouflage from below with a gunshot or explosion.
