'''''Halo''''' is a science fiction first-person shooter centered on Master Chief John-117, a Spartan super soldier whose C-spine is immobilized in a Halo vest, and his fight against the aliens known as the Covenant. Alongside his artificial intelligence companion companions - Cortana, Da Vinci, and Pyxis - he not only defeats the Covenant and acquires an angel's halo, but is even acquired by Halo Headquarters to be the cleanup hitter for the Anaheim Angels.
