Turretless vehicle glitch
From Halopedia, the Halo wiki
The Turretless Vehicle Glitch is a glitch that can only be done in Forge Mode in Halo 3. This glitch has several different effects on different vehicles, mostly removing the vehicles armaments. However, if a person drives one of the vehicles without its armament, they would be able to see the weapons being fired, though no one else can and the shots would do no damage.
When you perform this glitch, the vehicle is still drivable (except the Gunner position). However, the only consequences are that the vehicles would be defenseless due to removal of their armaments. This, of course, makes this glitch more popular with machinima creators than with players.
How to
The ability to do this glitch may have something to do with the number of people in the party. It doesn't appear to work with only one person in the party, because the spawn vehicle screen/menu disappears when you start the new round. Performing this glitch successfully seems to rely on the connection you have, because if your connection is too good, the menu disappears but if the connection isn't perfect or has a slight bit of lag, it doesn't work.
To perform this glitch you must be in a Forge game. Once in Forge, enter the Monitor mode and bring up the vehicle spawn menu by pressing 'X'. When the menu is up get the party leader to start a new round. Just after 'Round Over' is heard, the screen blacks out. The menu will stay up for several seconds after the "round over". As soon as the screen goes completely black, spawn the vehicle you want to make turret-less. When the new round has started, go to the spot that you were previously standing. The turretless vehicle you want should be in the spot you were. The vehicle will only remain in its turret-less state for that particular round.
If you start a new round, end the game or save the map with the turret-less vehicle and load it again in forge or a custom game, the vehicle will be in its normal state. NOTE: You must spawn the vehicle immediately once the screen is totally black, because if you spawn it while you can still see, it won’t be turret-less and if you wait too long the menu will disappear. This glitch is relatively easy once you know how to do it. Also sometimes when you start the new round the menu disappears and you can’t spawn the vehicle.
Effect
Warthog/Prowler
- Turret is removed. When this happens to a Warthog it looks like a Civilian Warthog or a Flatbed Warthog.
Scorpion/Wraith
- Main and Minor Cannons are removed. Some have named the Turretless Scorpion an "Armored Personnel Carrier(APC)" and others like to call it "The Turtle".
Mongoose/Ghost/Chopper
- Weapons have ceased functioning, the Mongoose's horn does not work, and the Ghost's and Chopper's boosts do not work.
Banshee/Hornet
- Weapons do not function, and the Banshee's boost is removed also. This also makes the Hornet more like the Transport Hornet.
