And here are a bunch of quick conceptual sketches for a variety of enemy units. My thinking with these was to push the anatomically inspired biomechanical feel of the War Machine into something more twisted and deformed. The various shattered AI remnants of humanity are at perpetual war with themselves, and create these machines to wage their battles. Attack types and methods of movement and combat are drawn from the broken and disjointed totality of human knowledge that's contained in the AIs, from militaristic science to the animal kingdom. Robot zombies if you will!
