I just had a flashback to a c64 game I used to love as a kid. It is about robots. There is a lot of grey, maybe all the graphics were grey, and it was either a side-scroller or orthographic with a slight angle. It loaded right into the game I believe, so splash screen and let you choose your starting robot. I can't remember exactly what the point of the game was, possibly escaping from a maze of different rooms? There was a timer as well, and once the time was 0 it was game over.
I know it was NOT paradroid. Any ideas?
