4-tentacled rock monster that crawls across the floor. It's cyborg backpack connects to a spinning-barrel energy weapon (via hooked curves) and a diagnostics display. The 4 tentacles are rigged with IK; for more detail you could remove the IK restraints and toggle "Auto IK" in the rig options (bones are in layer 2). All materials are pure nodes, there are no textures, but the tentacles and base body all have multiresolution sculpted data.
The original monster concept was designed for freedoom by Fredrik Johansson and Arborix and used with permission. Special thanks to raymoohawk.
