Brute Buddies

The Brute Buddies glitch is an AI-related phenomenon that occurs in the Halo 2 Campaign level Great Journey. It may be related to Halo 3 ' s "Friendly" Brutes glitch.

Instructions
In Great Journey, when you're in the Banshee and Sergeant Johnson is in the Scarab, fly to the ground near the Control Room and wait for another Banshee to fly down to you. Hijack it. The Brute pilot will fall out and land on the ground, but he will not die.

Fly down and get close to the Brute, and he will calmly walk toward you and follow you wherever you go. Even though he is making berserker yells, he will not attack you. If you do the same with others, they, too, will follow you -- so you can have an entire pack of harmless Brutes follow you wherever you want. However, if you kill one of them, and another one sees you, he will more than likely go berserk and attack you.

Also, in the same area, when you see the overturned Wraith, get out of your Banshee. The Brute there will not attack or have a weapon.

Halo 3
On the Halo 3 level Tsavo Highway, upon reaching the area where the Marines are pinned down by Brutes, their Choppers, and a vehicle barrier, you will find a Deployable Lookout Tower to the left, with a Brute wielding a Carbine. If you stand on his head and melee his shields down, he will go into a berserker stance and may yell, but he will simply stand there, looking at you whenever you move from his sight. This glitch will only occasionally work and has only been seen a few times successfully; it seems to work more frequently if you kill all other enemies in the area first.
