I took a Titan Tank from the C.O.R.P.S. line that I picked up at Goodwill and I sliced it up and re-configured the body and added some fodder parts from the Bruce Wayne Batman v Superman playset.

It still retains the electronics and I placed the flash bulbs under the chin guns so they still illuminate the underside of the guns as the gunfire sounds go of... Pretty cool. I still want to go back and weather the surface before I consider this shelf ready.
