Halo follows the events of an inter-galactic war between the last surviving members of the human race and an advanced collection of alien races known as The Covenant. The first title in the series, Halo: Combat Evolved, was the flagship title for Microsoft's Xbox video game console when it was released in 2001. The game achieved both critical acclaim and financial success, selling more than 6 million copies worldwide. The Grunt is a menace to the human race, and represents the vast majority of the Covenant infantry. The Grunts are the lowest tier of the Covenant hierarchy, and move in packs. They are expected to unquestioningly obey the commands of their Brute commanders.
The Brute Chopper makes its debut in Halo 3.
