Arcade Game: Star Trek (1982 Sega)

A 3D Vector (Wireframe) shooting ’em up game with computerized speech synthesis. The player finds himself the Captain of the Starship Enterprise, his mission being to rid the universe of a number of threats to the United Federation of Planets.
In order to destroy enemies the player may use either of two weapons : Phasers (the Fire button) or Photon Torpedoes. Each has unique properties.
* Phasers are instantaneous, can destroy only one enemy at a time, and are in unlimited energy supply.
* Photon Torpedoes require time to travel, can destroy many enemies, and are in LIMITED supply. Displayed in the Status screen, Photon Torpedo supply appears as a red bar (squares).
The primary enemy is the Klingon Battle Cruiser, which comes in three colors :* Red Klingon – ignores the Enterprise and sets out to destroy a Starbase, after which the Klingon turns purple.
* Purple Klingon – ignores Starbases and attempts to destroy the Enterprise by firing plasma energy balls. Purple Klingons will stop a certain distance away while attacking so as not to risk collision. After a certain period of time (depending on round), purple Klingons turn white.
* White Klingons – sometimes known as Maniac Klingons, these Klingons will move VERY QUICKLY and attempt to ram the Enterprise.
