Poseidon Wars 3D — About this game
Poseidon Wars 3-D puts you behind a training cruiser’s guns as an invasion approaches. Complete five training missions before taking on eight combat assignments, aiming at aircraft, incoming missiles and hostile ships. Fuel and damage determine how long you stay afloat, while hits can impair the radar, sonar, engine or weapons. Save surface-to-surface missiles for command ships and keep watching the instruments between targets. The original game supports SegaScope glasses, with a separate second-controller command for a 2-D display.
