Silent Perimeter · Sonar Tactics
Steer a submarine through three authored real-time combat missions. Sonar reveals contacts but broadcasts your position; go quiet to break live tracking, line up a narrow forward shot and manage three reloading torpedo tubes. Destroy a drifting mine, repel four submarines, then hunt a disabled sub through a minefield. Keyboard and pointer controls, chart heading, pause, field guide, retry and device-local mission records.
