Submarine Commander

Submarine Commander is a 1982 video game for the Atari 8-bit family written by Dean Lock and published by Thorn EMI Computer Software. A VIC-20 port by Gary York was released in 1983, and an Apple II version by Patrick Buckland the same year. The Atari version was re-released in 1985 on cassette as part of the Sparker brand of low-cost games. A version for the TI-99/4 was announced[4] but was not released until 1986 when a 3rd party bought the rights.

The game opens displaying the control console, whose square middle section shows a map of the Mediterranean with your current location displayed as a white cross and the locations of enemy ships as black dots.[5] Various status details are shown in the two rectangular areas on either side of the map.[6] Forward movement is controlled by the number keys, 1 for slow and 9 for maximum. On the surface the submarine moves more rapidly and recharges its batteries and air supply. The joystick provide directional control through the rudders and dive planes. This is a slow process, turning the ship right around in a 360 degree circle takes considerable time even at full speed.
