The game had you piloting a
Manta type spaceship, trying to destroy huge spaceships. I have my original
Uridium game, tape and case, right in front of me, bringing a
tear to my eye.
The huge spaceships had some things you had to destroy on its surface, some defending ships and a central core you had to blow before getting to the next level.
The music was by Steve Turner, was published by Hewson Consultants in 1986
