The year is 2515. Aliens have invaded Earth to claim it as their own. They are giant reptilian monsters ranging from 30 to 100 feet tall. In order to properly combat these aliens, the United Earth Military Alliance created the GAtCR (Giant All-terrain Combat Robot) units.

You were selected as the pilot of the latest GAtCR unit, Anubis. The machine had an experimental A.I that learns from combat.

"State your name and rank, pilot." Anubis' robotic voice demands as you sit inside the cockpit of the war machine.
