The Vril Sphere after merging with the Vril interface.
The Vril Sphere is an artifact that is found in the Zombie map Moon. It is an integral part of the Richtofen's Grand Scheme Easter Egg.
The Vril Sphere is a Vril artifact that was discovered by Richtofen while he was isolated with the M.P.D., following the teleportation test with Dr. Schuster. The Vril Sphere is designed to be a conduit to transfer energy between the Vril Interface on the M.P.D. and the Vril Generator. It apparently has the ability to create profiles for users of the M.P.D. via the Vril Interface, as this was heard on one of the audio reels on Moon.
