Star Trek Phaser Strike

Star Trek Phaser Strike is a handheld video game that was published by Milton Bradley in 1979, and released for the Microvision™ system (the first ever cartridge based handheld game console) at the same time as the film Star Trek: The Motion Picture.

Three phaser banks are placed at the bottom of the screen enabling the player to shoot in three separate directions at enemy ships represented by a collection of blocks.

The size, ranging from one to four squares, and speed of the enemy ships can be set as part of the difficulty settings by the player. In addition to allowing the player to specify the size and speed, the "changeable" option has the console randomly assigning those settings on a ship by ship basis.

The player is also able to choose the number of ships that will appear, in multiples of 10 up to 90.

The game ends after all the ships have been launched.
