He is doing as his thesis a 2d robotic game where you can program the robot for fighting against of the other player made robots. I will not speak about this idea more yet / in this post, but I'll show some stuff I have modeled and rendered for him.
These renders are not game sprites, but the models are real that can be used in the game by rendered from the different angle.
Maybe its better that i am not even trying to explain what all of these stuff are. You can use yourimagination for this. :)
The models will probably be better in the final version of the game. This is just art for him, so he can test his game engine.
