Subroc (Colecovision)

A fleet of hostile forces has assembled around your vessel. But this fleet is inlike any you've encountered. Flying saucers fire missiles and mines as they rush at you. Ships launch torpedoes. Line up your crosshair sight and shoot back! At the lowest altitude, your Subroc vessel fires torpedoes at the cruisers and drones. Raise your sight and unleash missiles at the flying attackers. Shift left and right to avoid enemy fire. Just when you think you've got control, the deadly command plane attacks!
