Foundation

"Deep in Chicago Industrial Zone 08 lies the decomissioned Tactical Autonomous Robotic Defence System testing facility."

Summary
Foundation is a multiplayer level in Halo 2, based on the Thunderdome levels from the Marathon series. It is a symetrical map with two levels; a lower center area and a raised walkway around the edge. There are rooms jutting from the corners of the upper walkway.

Weapons
The layout of weapons on this level is symetrical, like the map itself. An energy sword sits directly admist four psudo-building in the center. On the lower level, two rocket launchers sit beneath platforms opposite each other. There are holes in these platform to allow players to drop down to the rocket launchers, while an airlift to either side of the launcher allows access back to the top. On the other sides of the ground level, shotguns sit between two staircases, with a magnum available on the stair. On the small platform above the shotguns, a battle rifle and rocket launcher ammunition can be found. Within the "spur" rooms on the upper level, SMG's can be found.

Unlocking Foundation
Early in its release, an autoupdate was released that made Foundation available for all Xbox Live users. For non-Live users, however, Foundation remains hidden away thanks to a bug in the game. Bungie's intent was for Foundation to appear after you completed the game on any difficulty. Unfortunately, Foundation was only unlocked if you completed a "training event" on the final level. (The Great Journey.) This will was fixed with the release of the Multiplayer Map Pack on July 5th. Another way to unlock Foundation is to: Foundation should now be unlocked whenever you play with the account you created.
 * Create a new account.
 * Start a co-op game with an account that has unlocked The Great Journey on that level.
 * The new player must play to the final part of the level, where you fly a Banshee, then perform a Banshee stunt.
 * Complete the level.

Trivia
'''"Halo 3?" Symbol'''
 * If you look at the "pillar" in front of the rocket spawn from the sword spawn on either side, you will spot a symbol. The symbol is still a matter of debate. Some say it looks like the Halo 3 icon, others the Halo 2, and some just a symbol.
 * There is a symbol on a door on ground-level.
