The platform is different from the Armored War Elephant's because I wanted another look for the 'human' and 'undead' armies.
The humans are more intelligent and able to climb easier, hence the 2 levels and multiple firing positions. On the other hand, the skeletons have simpler positions, just 2 outriggers, and pile on more like a transport than a mobile artillery. I got 6 on there with weapons, maybe you can do more.
Note the size comparision; same width, height and length as the LEGO elephant.
Picture Note: The tusks are supposed to be rotated a little more towards the skull to better match the LEGO elephant. The tusks got moved while photographing. The photos will be retaken for the instructions, but for right now - "It is what it is."
