Background:
Bent on Humankind's extermination, a powerful fellowship of alien races known as the Covenant is wiping out the Earth's fledgling interstellar empire. You and the other surviving defenders of a devastated colony-world make a desperate attempt to lure the alien fleet away from Earth. Shot down and marooned on the ancient ring-world Halo, you begin a guerilla-war against the Covenant. Fight for humanity against an alien onslaught as you race to uncover the mysteries of Halo.

Gameplay:
Halo is a first-person shooter game where you take control of Master Cheif, a super soldier designed for combat. Travel through 10 different levels as you try to find a way into defeating the Covenant. Halo gives you a choice of using a lot of weapons including a rifle, pistol, rocket launcher, and even using the Covenant weapons. You may only carry up to 2 weapons that are different and up to eight grenades (four being fragment and four being plasma grenades). Rather than going through the entire levels on foot, you can also use vehicles to get around faster. Some of the Marine vehicles that are included are a warthog and a tank. Covenant vehicles include the Ghost and Banshee.
