I've 'upgraded' an old 'TRON' project - TRON tank V1.1 for the original figures. This upgraded tank adds lights & sounds to the turrent/cannon. In addition, this version upgrades interior detailing to stickers (no more visible glue through the interior details), upgrades the wheels (much smoother rolling movement), and upgrades the interior to remove the seam lines. All the other features people love from the original are still present and the tank retains the incredible look and size!
