Halo 3

I played Halo 3. It is the best. It is so cool. On the game you are called Spartan-117: The Master Chief. There is the Arbiter, Cortana, Sergeant Johnson, the Prophet of truth, Grave-mind, and Commander Miranda Keyes . The Master Chief is the last of the elite SPARTAN II soldiers. In the little book that comes with the game it says:

They're genetically superior, highly trained super-soldiers who stand nearly 7 feet tall, and MJOLNIR Mark VI powered assault expert in all weapons and combat systems and can run faster, jump higher, and hit harder than any normal human. Honed by years of battlefield experience, he has an unparalleled natural talent for war.

The disgraced Commander of the Covenant fleet of Particular justice was stripped of rack and forced to don the ancient armor of the Arbiter--an Elite custom where a warrior is sent on a suicide mission to claim great honor in death. The Arbiter discovered, however, that the Covent's Great Journey was a lie and he subsequently started a civil war that has shaken the foundations of the Covenant. The Arbiter's people, the Elites, have joined Humanity's strggle against the rest of the Covenant. The Arbiter is on the good guy's side.

Sergeant Major Avery Johnson is the battle-hardened and longtime cohort of the Master Chief. An excellent soldier and unmatched marksman who's seen more than his fair share of combat, no other Human know the Master Chief like Johnson does. Johnson is never more at home than in the thick of battle and he will do anything for his man and his home-world.

The Grave-mind has a army of flood. There is a lot of them they can eat you!
