Grunt Aerobics

Grunt Aerobics is a trick/glitch (more like a glitch though) that is done on the Halo: Combat Evolved campaign level Assault on the Control Room.

To see Grunt Aerobics you grab the Banshee earlier in Assault on the Control Room (See Early Banshee), you can finish the level without having to open those big doors at the end, and fighting the hordes of Covenant. Just park your Banshee backwards so that the front is facing toward the ramp leading to the top. Once it is backed up against the door as far as it will go, then get out. It should push you through the door and all the enemies will be frozen, since the door was never opened. The only things that move are little circles of Grunts that jump up and down in sync, one after the other.

You can also do this with a Ghost by strafing to the right towards the door and getting out of the Ghost so that you are out just before it hits the door. This method is easier than the Banshee method.

This strange Grunt behavior can be witnessed in the Pillar of Autumn on any difficulty, when you reach the point that there is a long hallway with a couple of Grunts at the end (it has some Bumblebee life boat docks at the side) or on the Silent Cartographer, when you come out of the security building and look over at the grunts on top of the ridge in between the ocean. Take out your M6D pistol and zoom in on them, but don't shoot them, as they will start jumping in the same way as in the fifth level.

Trivia

 * Similar behavior can be witnessed on the Halo 2 level The Arbiter when played on Legendary difficulty. The Grunts are seen dancing in synchronization around the Grunt Birthday Party skull.
