I originally posted this on the HBS battletech forums, but it seems that those forums are shutting down next week, so i thought i might as well post it here as well.
It probably makes more sense here, since Helepolis isn't a mech that's appearing in the game anyway.
I always liked weird and unusual mech designs, and seeing how Helepolis is really one of a kind mech design, with the 20 ton Sniper Artillery Piece crammed into it.
I know i'm not the greatest artist around, but i felt it came out pretty well.
