Star Trek: Phaser Strike was a game cartridge produced for use with the Milton Bradley Microvision Handheld Game System. It was one of the first such games made for the system when it was released in 1979, the same year that Star Trek: The Motion Picture hit the theatres. It was also the first handheld electronic game with a Star Trek theme.
The object of the game was to destroy the various Klingon "ships" (in reality, sets of block-like pixels ranging from 1 to 4 pixels in length) with your three "Phaser banks", located along the bottom of the screen; one in the center (firing straight up), one in the left corner (firing diagonally up & right) and one in the right corner (firing diagonally up & left). Game settings allowed you to specify the size, speed and number of ships in each "attack" (round of play).
- NOTE: Apparently during the existance of the Microvision system, Milton Bradley's contract with Paramount ran out. The game cartridge continued to be produced, but was renamed simply Phaser Strike and re-released with new packaging that made no references to Star Trek. According to sources, some of the newer versions of the game were released in older boxes with the original Star Trek title.
