The map "Forge World" in a Halo: Reach is just a large map with nothing on it, other than like trees and rocks and stuff. There are only 4 items which you can place in Forge mode on "Forge World". 3 of which are in the spawn category.
It's quite simple really, you don't. It is completely impossible for a typical user to be able to spawn any type of AI in Halo 3's Forge mode.
monitor mode is only available in forge mode and when you are in it you can spawn alot of stuff such as cars, scenary, weapons, teleporters, and spawn points.
spirits are not in halo 3
Yes you can. You could just go into forge, spawn in some weapons, and fight to the death as much as you want.
