Credit to RayMooHawk for the concept (used with permission):

At 9K tris, with diffuse and normalmap textures, this model should work well in modern game engines. It's rigged, textured, and animated, but the rig and UV-map were just quickly generated so there are some issues but it should work allright for most uses. I can upload the highpoly / midpoly .blend on request.

Created for the FreeDoom project.

EDIT: Added a toon texture. 2 Materials are included, one with the diffuse and normalmap textures, and the other with a toon texture, not meant to be used together.
