Andrew Braybrook made the C64 do things it had no business doing. Uridium is a shooter over giant metal dreadnoughts in space, and the scrolling is so fast and so smooth that people used it to show off what the machine could do. The Manta flips on its side to slip between towers, and the surfaces below you actually look like brushed metal. On a C64. In 1986.

Fifteen dreadnoughts, each one to be cleared and then destroyed by landing on it and letting the fuse run. I never stopped being impressed by this game, even after the Amiga arrived. Some code is just art.
