Periscope Up

Periscope Up places you in a tense underwater mission where you pilot a submarine to stop a system spiraling out of control. You explore a hazardous complex, collect vital items such as keys and fuel, and use your onboard weapons to overcome obstacles. Along the way, deadly laser beams and crushing passages demand precise navigation and careful planning. Only through thorough exploration, smart decisions and good timing can you reach the supercomputer in time to prevent global disaster.
