[SUBMISSION] Scorpius Zombie Tank

I decided to clean up the unused Scorpion Tank from DukeNukem3D. Now Doom's zombies have another deadly toy to play with.

Description:
The Scorpius is a diabolical product of the UAAF's R&D tomfoolery.
This menacing marvel, under the command of a relentless Former Commando,
packs a punch with a pair of forward-facing energy blasters, and an
earth-shaking tail-mounted plasma cannon.
