Halo is the second campaign level of Halo: Combat Evolved and it begins on the morning of September 19, 2552. It gives us the first "on the ground" view of Installation 04. As the only survivor from the Bumblebee escape pod crash, John-117 fights against the marauding Covenant forces, while searching and rescuing other survivors from the Pillar of Autumn. This is the first level in the series in which Jackals, Spirit dropships, and Banshees are encountered.
