The alien armada is closing in on your Mother Ship. You're awesomely outnumbered, and they attack and attack... In Space Battle, the player is put in command of three fighter squadrons, tasked with protecting their mothership from an alien aggressor. The game has two modes that the player can switch between: a "situation map" where the player sends their own fighters to intercept alien squadrons, and a battle screen that allows the player to fight the enemy directly by destroying their ships with lasers.
While the player can only engage in battle with one squadron at a time, the player's other squadrons will engage with the enemy in real time, via a simple AI. In this run, Winslinator defeats the alien armada in record time by deft control of the battle screen, allowing the blue and white player squadron to destroy their targets quickly, then manipulating luck such that the AI proceeds to defeat all of the remaining enemy fleet.
As a fun side-note on the development of this game: the alien invaders are clearly designed after the Cylon Raiders from the original Battlestar Galactica. One of Mattel's subsidiary companies had rights to produce Battlestar Galactica toys, but it was discovered late into development of this game that Mattel itself did not get the rights to the name, so this game had its name changed to Space Battle but still featured the not-Cylon sprites.
