Astro Fighter

Astro Fighter is a single player space shoot-em-up, where formations of ships appear at the top of the screen and move downwards in a pattern that depends on the type of ship. The player's goal is to pilot their ship to destroy the enemy before they reach the bottom of the screen, whilst avoiding enemy fire. Being hit by the enemy loses one of the player's three lives. If the enemy does make it past the player, then the same formation is repeated, but this time the player moves backwards and forwards a little further up the screen. There are up to five waves of enemies (cyan, magenta, green, yellow and white) per round, followed by a screen in which you must defeat "The Master", which is a single large ship with an eye in the middle.

To make things more difficult, the player starts the game with a limited amount of fuel, which reduces as the player maneuvers. The game is over when fuel runs out, but it is replenished every time "The Master" is defeated. As in "Space Invaders", the player can only have one bullet on the screen at a time, and can only shoot vertically.
