I am an undead Arbiter, revived by an unknown god. I use my only tactic to make you feel my pain; The ''Ultimate Sacrifice'' requires you to kill me, but in return, I have to drag you with me into death by revenge or gravekill. We Elites are powerful.
Humans are now our allies, so let us put our strenght together and banish those Brutes and the Parasite to the nothing.
How about a sequel of Halo 3. It could be the Arbiter and his bros who could be in war against rebels of all Covenantes races (Grunts, Jackals, Brutes). It will be like a total alien war, but your playing as the Sanghellis team, playing as the Arbiter on Campaign. It will be titled like Halo: The Arbiter Chronicles. I got the idea for multiplayer but it's too long to explain.
