Invincible Grunt

Template:Ratings The Invincible Grunt glitch can only be done on The level Scared icon 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.Template:Fact

There is also another way to do it:

• Let the Grunt activate the piston
• Throw a grenade on the Grunt for the test
