Infinity (Halo: Combat Evolved map)

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, hence the name infinity. 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.

Summary
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 and a shotgun. 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 a Rocket Launcher each. 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.

As previously stated, this map is based upon the Halo: CE level Halo.

Glitches

 * There is a glitch and a common anomaly that you can exploit within both the bases: 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).
 * Another glitch is using a Banshee to get out and pass the invisible wall while hovering and backing into the wall, much like getting to the sniper's rock in the multiplayer level Blood Gulch. The location, however, is unconfirmed.

Trivia

 * The two raised tracks in the center of the map make a partial figure eight, which represents Infinity.
 * If you stand in the bases and look up when they fire their beacons, it looks like the beacon goes to the center of the ring (In space). You also can't see the beacon from the other base. However, if you go to a certain spot near the intersection of the canyon, you can see both beacons. The reason they both go to the center is because the bases are at a slight angle that is not immediately noticeable, as is the curve of Halo's cylindrical form or the Earth's spherical form.
 * The structures look similar to the beacon towers in Halo and the bases in the Halo 3 map Valhalla.
