I'm working on a new 15 mm project... and it's a weird one. Here's some rough concept art:
What the? OK, some explanation: As we all know from watching "Raiders of the Lost Ark", the Third Reich were interested in some pretty fringe stuff - occultism and black magic and so on. This is the product of some kind of Nazi occult ritual gone horribly awry on the battlefield, resulting in the tank being "possessed" by some kind of demon or entity :O Kind of like the Chaos vehicles in Warhammer 40,000.
I'm basing this on a 15 mm Flames of War tank, and probably some GW Chaos or Genestealer bitz for the legs, since I'm not such a hot sculptor... I might have some mixed troops (Allied AND German) trying to destroy the thing, to emphasize what a universal menace it is. Should be fun :)
