Infinity (Halo: Combat Evolved map)

4-16 players, Supports vehicles

Infinity is a level exclusively unique to Halo PC/Mac's multiplayer. It is the longest multiplayer map, being a long canyon shaped in an ∞ (Oroborus/"Infinity") symbol, tying in with its name. It is meant for 10 people or more. It's one of the best maps for the race gametype. It is recommended you have good marksman skills for this map as all close range weapons are unavailable.

Infinity consists of two large bases, containing a large signal beam emitter (going into the beam will kill you), as seen in the single player level Halo. One emits a red beam, the other blue. It houses two Banshees at the top of each base, as well as Shades a bit further down. A smaller, secondary building lies below, containing a health pack. On top of it is a Fuel Rod Gun(unless the mode is CTF, in which case the heavy weapon is instead located in the middle of the cross section plateaus near the bridges). In the center of the map, there are four long suspended bridges, similar to the ones seen in the beginning of the "Halo" campaign map. The top two bridges hold Rocket Launchers. At the ends of either of the lower bridges are teleporters and in the middle are health packs. There are also ladders leading to the top bridges. There are small ridges in between each upper bridge that each contain a Shade. There is also a small maze-like structure on one of the routes to blue base. The Flamethrower spawns here.

Glitches
You just need a Ghost. Get the Ghost up to the top of the base (which ever one you're at) and then get it in to that little spot between the base and small walk way that leads up to the Banshee(s), then when its in there, just get under it's "wing" then try to flip it over, but the way its in it will just come back down on top of you then you will be launched into the base but you'll need to move yourself to get into the area that the laser fires from, if you don't you'll just die (and you might not get into there because you'll either have the Ghost the wrong way or by just something weird).
 * There is a glitch that you can do at the bases:
