Uridium (released on the NES as The Last Starfighter) is a science fiction side-scrolling shoot 'em up originally designed by Andrew Braybrook for the Commodore 64, and later ported to other 8-bit machines. It consists of fifteen levels, each named after a metal element, with the last level being called Uridium (a fictional metallic element, not to be confused with the real metallic element iridium). The manual quotes Robert Orchard, who invented the name as saying "I really thought it existed".

This side-view shoot 'em up involves trying to retrieve two nuclear weapons which have been stolen by terrorists. These are located at opposite ends of the playing area, so you can pursue them in either order. Needless to say, the terrorists have plenty of forces out to prevent you getting too far. Unusually, the game features both a helicopter and a tank - you choose either from the base, and can fly/drive back there to change. The best strategy is to use the helicopter to shoot out air-based enemies and repair the various bridges, then return for the tank. You get 4000 seconds in which to complete all this, and losing a life costs you 500 of these.
