Action Game Reactor for ZX81

'Reactor' is a 1984 action game for the ZX81 16K. The player is tasked with managing a nuclear power station. An unfortunate mistake leads to the activation of a self-destruct sequence, mistaking the button for a light switch.

Players navigate a maze to locate three pieces of secret code. Once collected, these codes allow access to the control room, where players must rearrange them to deactivate the reactor and prevent disaster.
