Gorf is a Commodore 64 game that consists of five levels. The first level, Astro Battles , has the player's ship behind a defensive shield, defending against an alien attack. The level is a top-down view, with the player's ship and shield on one side and the aliens on the other side; this level bears resemblance to Space Invaders.
The gameplay of Gorf is action-packed, with the player navigating through levels filled with enemy ships that need to be destroyed. The second level, Laser Attack , features a formation of ships that swoop down and fire lasers at the player's ship. Bonus ships also appear in this level.
The third level, Galaxians , is similar to the game Galaxian, with ships constantly dive bombing the player's spaceship. This mission only appears in the Arcade version.
The fourth level, Space Warp , has the player entering hyperspace and switching to a behind-the-ship view. One by one, alien vessels come out and fly in a circular formation shooting at the player's ship. The player's goal is to destroy each one.
The final level, Flag Ship , features a single large Flag Ship with a weak spot that can be hit to instantly destroy it. However, the player must first shoot through a similar shield that they had in the first level.
Finishing the game increases the player's rank and starts the game over at level 1 with a faster game speed for more challenge.
