Yes, the next version of mech designer! I was working on a new interface when I simply decided - screw it. The new interfaces where not as classic and I enjoy this one more for one reason - Gundam baby, yes this is the addition of the Gundam! If you would like to see biographies on the previous mechs, GOTO MECH DESIGNER 3 OR PREVIOUS, AND REVIEW OR VOTE. I hope you enjoy this, ALOT, ALOT, ALOT of work was put into this. Enjoy.
