No weapon glitch

The No Weapon Glitch is a glitch done in Halo 2 that removes the players weapon. It requires an oddball and a plasma pistol to work. First, you would need the find the oddball, then charge your plasma pistol. Then, walk over the oddball and pick it up while still charging the pistol. If you did it correctly, you will have no weapon in your hand, and have no reticle. However, if you come in contact with any weapon, you will automatically pick it up.

This is can be used for some fun gametypes if everyone cooperates, or can be used for making machinima. Please note, however, players using the spartan player model can still throw grenades, while Elites can't when using this glitch

In addition this can be done in campaign. I would suggest outskirts because the blind skull can be grabbed on any difficulty or regret because the assassins skull is always there (it just doesn't work on heroic or lower). First do the glitch where you hold three of the same weapon with the plasma pistol. Drop your duel wielded one. Switch between your weapons to be sure that you have two plasma pistols. Then go to the levels skull. Do the trick as mentioned above but with both plasma pistols. You should now be holding no weapons, but with the abundance of weapons in campaign it will be very difficult to avoid weapons on the ground so i would carry the levels skull with you so you can redo the glitch.
