Mars Mission / Astro Blaster

Mars Mission / Astro Blaster is a compilation of two games released together for the BBC Micro.

Astro Blaster: Played from a 1st-person perspective, the player is put in command of the S. S. Destroyer, as they patrol the asteroid belt hunting alien ships and asteroids. The player moves through space with a crosshair in the center of the screen to line up and destroy enemy vessels. If the player is hit, they lose shielding. As they move, they lose fuel. The player must destroy a certain number of vessels before their fuel or shields run out to advance to the next level.

Mars Mission: As the pilot of a spaceship, the player must rescue four explorers on the Martian surface via a shuttlecraft, and return safely to the awaiting spaceship. The player starts at the awaiting mothership, which moves horizontally back and forth at the top of the screen. The player must launch and land on one of the four landing pads at the bottom of the screen while avoiding asteroids that move horizontally across the screen. The shuttle can move left, right, and use fuel to slow its descent. The player has limited fuel to make all four rescues. After a successful landing, the asteroids turn to alien ships, and the player must make the ascent to the awaiting moving mothership.
