''Submarine Commander'' is a 1982 video game for the Atari 8-bit 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.〔(【引用サイトリンク】url=http://www.vizzed.com/play/submarine-commander-appleii-online-apple-ii-6355-game )〕 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 but was not released until 1986 when a 3rd party bought the rights. The game is a fairly detailed simulation of the operations of a German U-boat during World War II. The action takes place in the Mediterranean Sea, where the player has to track down a number of allied convoys and then approach them underwater to attack with their torpedos. Compared to most other strategy games of the era, ''Submarine Commander'' works in real time, while compared to the more typical shooters of the era it is considerably more in-depth. ''Submarine Commander'' is the first submarine simulator game released for home computers. An Atari 2600 game of the same name was released by Sears Telegames, but is unrelated, it is an adaptation of the arcade game ''Sea Wolf''. ==Gameplay== 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. Various status details are shown in the two rectangular areas on either side of the map. Movement is controlled by the joystick and number keys. The joystick does not move the submarine directly, but moves its controls, which in turn cause slow movement over time due to the forward speed. The speed is controlled by the number keys 1 through 9, and the submarine travels faster on the surface, as well as recharging its batteries and air supply. Turning the ship right around in a 360 degree circle takes considerable time even at full speed. The main display in the center can be switched between three modes, the map, a sonar display, and the periscope. Typically a mission proceeds by starting on the map display while surfaced, and chasing down one of the convoys. When one is sighted, announced by a bonging sound, the player dives the submarine to attack depth and continues the approach using the sonar display. Once the range has closed, they raise the periscope and attack the ships with the torpedoes. The periscope shows ships if they are within one mile and the submarine is above 50 feet depth. There are four types of ships in the convoys, including oil tankers, cargo ships, destroyers and patrol boats. All of the ships are armed with at least one gun, and will fire on a surfaced submarine. If the submarine is underwater, the destroyers and patrol boats will attack, while the tankers and cargo ships attempt to flee. Successful attacks cause damage to the ship, which repairs slowly over time. The game ends when the air runs out, the hull reaches damage level 9, there are no torpedoes or fuel left, or all the convoys have been destroyed. The game then assigns a score based on various factors. The game features nine difficulty levels, which change the number and makeup of the convoys, along with consumables. At the lowest level there are five convoys and the player has 80 torpedoes, 250 fuel and battery that holds a charge of 70. At the highest level, 9, there are 9 convoys, 40 torpedoes, 140 fuel and a battery that can be charged to 30. In levels 7 through 9, more than one torpedo may be needed to sink a ship. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Submarine Commander」の詳細全文を読む スポンサード リンク
