No Weapon

The "No Weapon" trick is very easy, basically it makes you drop the weapon that you have, and if you don't have a secondary weapon, you will have no weapon. This is great to do while shooting a machinima or video and you are acting as the cameraman. This glitch/trick works in both Halo 2 and Halo 3.

How to in Halo 2

 * 1) Make sure it's an Oddball, Capture The Flag, or an Assault game.
 * 2) You can have only one weapon and that is a Plasma Pistol, no secondary weapon.
 * 3) Charge up the Plasma Pistol and walk up to the Oddball, flag, or Bomb.
 * 4) Pick up the Oddball, flag, or Bomb while keeping the Plasma Pistol charged.
 * 5) Drop the Oddball, flag, or bomb quickly and you should be holding no weapon.

How to in Halo 3
Have player two pick the weapon up and at the same time have player one delete it.(This takes perfect timing but it does work)
 * 1) Start a forge game with at least two players.
 * 2) Have one player enter monitor mode and spawn a weapon.
 * 1) NOTE: even though your weapon is gone you're still in combat pose, you can use the lower your weapon glitch but the game will still think you have a weapon so you will look like you have an invisible weapon. For this reason machinima makers that want realisim should use an Energy Sword.
