Arm glitch
From Halopedia, the Halo wiki
Template:Ratings The Arm Glitch is a glitch that can cause your arms to be bent or missing.You can do this glich by having two people (one in monitar and the other in human mode) pick up the weapon at the same time ( I suggest using foundry in the heroic map pack. As seen in the video, it can cause the character's arms to be bent or missing. It can only be achieved through Forge. Almost every gun has a different arm bend, often encouraging people to try different guns. Different weapons can have different effects and can do different things. When using a Sentinel Beam or a Gravity Hammer, if you hold RT the users arms will blow off and if you delete the weapon, he will have only one arm left and he should be invincible. This trick is called, Halo 3's EXO arm glitchbecause the EXO clan found it.While the person has one or no arms hit them in the back until they die, this will cause your screen to lag and the persons body should be floating. When it hits the wall it will start doing random things like change color, or the head will disapear, this will go on until the body disapears.
Tactics
A good tactic is to have a team who knows how to use it and use it against oblivious enemies. The shot normally doesn't come from you and can fool the enemy. Sometimes a shot doesn't come at all, but it still hurts the enemy. One part of the glitch can make the gravity hammer even more dangerous. It is called the Nuclear Bomb Glitch. This glitch is better for a last resort method, and it is very powerful.
