Year is 2055, energetic resources are nearly depleted. The B.A.E.R. (Bureau of Advanced Energetic Resources) had discovered the first deposit of praxillium, a new fissile element, more powerful than uranium, and not producing any nuclear Waste. After an explosion, the mining site remains silent, so the B.A.E.R. send the S.T.O.R.M to go and see what is happening. You are Andy Steale, pilot of the Submersible Tactical Operational Reconnaissance Module.

The game is mainly a side-view Shoot'em up. You can use a robotic arm to pick up devices, you can send scuba divers to go in thinner passages). There is also 'interactive shooting' phases (rail-shooter with prerendered cinematic background).
