Jetpac
Ultimate's debut
Jetpac launched Ultimate Play the Game with addictive single-screen action, challenging players to build a rocket while fighting aliens across increasingly difficult waves.
Jetpac introduced the world to Ultimate Play the Game. Its premise — assemble a rocket, fuel it, take off — carries more game than it looks like. Jetman’s momentum, the responsive controls and the escalating waves made it an instant classic and set the standard Ultimate would be judged against.
📘 It runs in 16K. CRASH listed it as “Ultimate, 16K £5.50”, which is the fact that explains the rest: every screen, every alien and the whole rocket-assembly loop fit in the smaller Spectrum’s memory, at a time when 48K games were already common. Ultimate’s reputation for getting more out of the machine than anyone else starts here, on the model with least to give.
