Centipede

Superior Software's conversion of the Atari game. The BBC Micro conversion was by Richard Hanson.

You have to shoot the sections of the centipede as it moves through the mushrooms, before it gets to the bottom of the screen and touches your ship.

The game was originally released as Centibug, but was re-released and re-named after Superior Software got the license for the official port of Centipede.
