A lot of variations can be achieved, a few can be seen from preview images. Helmet/cap, tunic/shirt, two texture variations for legs, different gear on/off etc.
Preview images are not rendered, but realtime, taken form Blender viewport. They can look as good or even better in the application game engine.
Ready to animate with Ik set up in Blender version and full body IK in Maya version.
