Halo: Combat Evolved Anniversary - Grunt Skull Video

Once the skull has been activated, every grunt’s methane tank will explode like a plasma grenade when killed. Watch out for the grunt chain reaction!
The Grunt Skull is an exclusive, game-modifying skull that changes the rules of the game for an explosively humorous experience, “Grunt Funeral” sends “Halo’s” most lowly and lovable enemy out in a blaze of glory. And plasma. And then more glory.
