It was followed by two official sequels, the console and computer title Mighty Bomb Jack, and the arcade game Bomb Jack Twin and Bomb Jack II, which was licensed for home computers only. The highest known score was by Mr G Jones from London: 6 746 800. Bomb Jack is a hero who can perform high jumps and float in the air. His goal is to collect all red bombs on the screen.
