Battle Planet

Battle Planet is a 1-player arcade shooter for the BBC Micro.

Human civilization is threatened by the approach of alien Battle Planets, huge spaceships the size of planets than can destroy whole worlds. These seemingly invulnerable spaceships have one weakness, located in a trench on the planet's surface. The player's mission is to fly into the trench and launch a plasma bolt into the Battle Planet's heart.

Played from a perspective behind the spaceship, the player can move their ship left, right, up, and down, as well as shoot forwards. Oncoming Robot Fighters try to destroy the player. Ships that approach from the front must be avoided or shot, while only shields can protect the player from ships that approach from above. As the player approaches their target, the invincible commander ship approaches from behind to threaten the player.
