This one is a bit experimental.
You are a damaged alien spy probe.
With visual systems malfunctioning all you have left for navigation is some particle detector.
You have to reach your pickup zone before system failure.
Basically you have to navigate through a 3d environment in first person view while the only thing you see are a few dots of the walls here and there.
