Astro Battles, the game's first mission
Gorf is a fixed shooter in which the players take control of an unnamed starship from the Interstellar Space Force, capable of moving freely on all directions around the lower third of the screen, in an attempt to prevent the Gorfian Empire from conquering Earth. Gameplay comprises five distinct missions; each mission presents its own distinct playstyle, but the central goal of each is to destroy all enemies. Successfully completing all five missions increases the player's rank, which represents the current difficulty level of the game, and loops back to the first mission. Gameplay continues until the player loses all of their lives.
