Cosmic Avenger for the Coleco Vision. In Cosmic Avenger you control a space fighter that can shoot an unlimited number of missiles and can drop an unlimited number of bombs. While flying over the domed cities and hostile seas of an alien planet, your ship will be barraged by a host of enemy firepower, such as barrage missiles, vertical rockets, diagonal rockets and tank missiles. To score points, you must shoot or bomb alien vehicles and weapons, including submarines, tanks, barrage guns, UFOs and launch pads. A small radar screen is provided at the top of the playfield, which provides advanced warning of incoming enemies.
