I don't get it.
Is it like rugby or something?
In Halo 3, Griffball is a Assault gametype where two teams of four get Gravity Hammers and Energy Swords, no shields, and friendly fire is on, the person who gets the bomb turns orange like the character Griff from Rooster Teeth's series Red vs Blue, the bomb carrier also gets a x2 overshield and i think becomes a little faster than non-bomb carriers, there are 5 rounds in the game
