The ONI Reap-X Quad Walker Variant, designated Tarantula, is the next evolution of the Quad Walker. Possessing four treads, one mounted to each leg, the Tarantula can operate as both a walker, allowing it unparalleled mobility over rough terrain, and as a tread based weapons platform, giving it greater speed over smoother, less extreme terrain. The platform has also gained an upgrade in offensive capabilities, including the addition of three M41 Light Anti-Aircraft guns, two mounted atop the plasma cannons and one mounted underneath the body of the walker. With the addition of the treads and the new weapons systems, the Tarantula has also been outfitted with a dumb AI to help with the operation of the vehicle, particularly the targeting and fire control systems.
