Harvester

A Harvester is a Covenant remnant walker used during large-scale excavations and in the search of artifacts.

Design
Harvesters are the most massive Covenant land vehicle to date, with only the "Super" Scarab being comparable in size. Generally used in long-term invasions, they are not commonly seen by UNSC personnel. Much like the Scarab, it appears to be composed of some form of Lekgolo assemblage, as sections of its interior display exposed Lekgolo worms. As with most Covenant vehicles, the Harvester has an organic appearance. It is much more beetle-like in appearance than the Scarab due to its overall shape, heavily textured outer "skin" and a hatch at the front of the machine that resembles a mouth and eyes. The interior is composed of multiple massive chambers that resemble dark subterranean caverns, linked together by smaller hallways and illuminated with pale green light.

History
A Harvester was once encountered during the Requiem campaign, where it was disabled by Fireteam Switchback, who mysteriously vanished in the firefights afterwards, leaving no bodies or signs of struggle, only their IFF tags. Fireteam Crimson was sent in to investigate. Crimson managed to kill the remaining crew of the Harvester and further disabled the walker by destroying several consoles inside. Sometime later, the Covenant re-took the Harvester and captured several doctors to activate the walker, but it was not successful because the power supply was destroyed. When Requiem was put on a collision course against the sun, the Fireteam Crimson was sent to retake the Harvester and use it to reach one of the artifacts that prevented the UNSC Infinity leave the planet. After stealing the power source from a Lich, Crimson returned to the Harvester and active the walker. After that, Crimson used the Harvester's Plasma drill to excavate a tunnel deep enough to reach the artifact and turn it off. The Harvester was destroyed when Requiem was consumed by the star.
