The game, Halo 3,
one of the most popular games for the Xbox 360, created by Bungie, mostly used for the multiplayer, as the campaign sucks.
In the campaign, you are
the Master Chief, also known as Spartan 117, John, and the Anti-Chri- oh wait nevermind. He is part of the Spartan II (2) project by the UNSC. He is the last remaining Spartan as of 2552.
Halo, a rip-off of Larry Niven's Ringworld, is a large super-weapon used to destroy the Flood. It has only been fired once, which destroyed the Forerunners and all sentient beings within it's radius, since, in actuality, the only way to kill the Flood is by starving it.
The Flood are a parasitic alien life-form that have the ability to latch on to a sentient being and turn it into, basically, a zombie. Also known as a rip-off from Valve's game, Half-Life, the Flood are extremely smart and are able to do many things, like repair ships. The Flood are able to spread with the spores they emit.
The Forerunners are the ones who controlled the Halo rings before they fired one and killed themselves (how smart). It was supposed to starve the Flood, and it would have, had the Covenant not have invaded the ring the Flood previously occupied.
The Covenant, a group of many- uh, actually, five- different species (Brutes, Grunts, Drones, Hunters, Prophets (and previously Elites)). They are the ones who believe that Halo will "Save" them, instead of kill them (which it does).
The Elites were once part of the Covenant before they found out the truth about the Halo rings, as told by the Gravemind. They later side with the UNSC humans.
The Gravemind is the Flood's brain, I suppose. It is extremely
intelligent, and I believe it is the one that plans the Flood's attacks, and so forth.
A particular Prophet, the
Prophet of Truth, is trying to fire the Ark, telling the Covenant that they will be Save if they believe in God- I mean Halo (although I think he knows that Halo is actually a weapon). He tries tries to fire the ring, but fails. Three times.
The Ark is like the
command center for all of the seven Halo rings. It also has a back-up Halo to replace the fourth Halo ring destroyed by the Chief.
To sum it up, the Anti- I mean
Master Chief goes to kill Jesu- I mean the
Prophet of Truth to stop him from firing God- I mean the Halo rings.
