Tri-Gates

Tri-Gates are to this day one of the most debated Halo topics. People aren't sure what purpose they have, if any. Some people think they are glitches, some say Easter Eggs, some say they are just graphics in the level, and some say they are just graphical errors. They have made appearances in Halo 2, and a few have recently been discovered in Halo 3, by General Heed and a few other glitchers. I, nofatchicks787, have found the Tri-Gates' counterpart in Halo 3, and I call them Square-Gates. Some Tri-Gates may exist in Halo: Combat Evolved, but have yet to be found.

Halo 2
The majority of the known Tri-Gates are in Halo 2. There are quite a few famous ones. These are just some of the most famous Tri-Gates in Halo 2.
 * Cairo Station Tri-Gate: Get out of the level by using the Cairo Station Vacation. Follow the path to the back of the map. Jump down the ledges and there it is.
 * Terminal Tri-Gate: There is a Tri-Gate outside the multiplayer level Terminal. To see it, get out of the map by either superbouncing, or sword canceling.
 * Outskirts Tri-Gate: To see this Tri-Gate, get into the water outside the level, and there is a black rectangle floating in the water that produces water effects when shot.
 * Delta Halo Tri-Gate: To see this Tri-Gate, get outside the level using one of the Delta Halo Vacations, and then go into the lake with the temples in it, and go as close to the level as you can, and its on the rocks.

Halo 3
There have been a total of 10 Tri-Gates found in Halo 3 by General Heed.
 * The Ark Tri-Gates: To see these Tri-Gates, get out of the level using The Ark Vacation. The Tri-Gates are on the top of each of the long ass pillars on both ends of the map, and spread all over the floor of the area on top of the first Tri-Gates. In this area, be VERY careful not to trigger ANY loading points or you will be deleted from the map.
