Invincible Grunt

The Invincible Grunt glitch can only be done on Halo 2.

Play the the level Sacred Icon on any difficulty. At the beginning there is a red Grunt Major cowering next to the piston. To make the Grunt invincible, follow the steps below:


 * Arm it with a Plasma Rifle.
 * Push him off onto the first level.
 * Melee it, throw a grenade at it, and shoot it. It won't die.

There is also another way to do it:


 * Let the Grunt activate the piston
 * Shoot the Grunt for the test

WARNING:If you kill any Contructors, the glich will disable
