Jetpac

Jetpac is a ZX Spectrum, VIC-20 and BBC Micro video game developed and released by Ultimate Play The Game in 1983.

In the game, Jetman has to first assemble his rocket (which comes in kit form), and then fill it with fuel before taking off to the next planet (where the procedure is broadly repeated). Along the way Jetman has to fend off the attention of intelligent (and not-so-intelligent) aliens, while making off with their valuable resources.
