I haven't done a Robocraft C&C build in a long time, but since Megabots are back in the game and with the new introduction of Mega Rail Gun, there was simply no bigger desire for me than to finally make my own version of Mammoth Mk. II, including all it's main and secondary weapons. It has fully operational (and very accurate to the source as well) Mega Rail guns, chin cannon and a pair of SAMs, all working nicely.
