How it works & what to expect
The original DOS shareware release runs inside a WebAssembly build of DOSBox. It is under 200 KB and loads at once. It is a 16-colour EGA game and runs at full speed on any device.
Playing it
Arrow keys move, Ctrl jumps and Alt fires. Ammunition is limited, so do not shoot at everything. In each base you need to find the floppy disk and take it to the computer to shut down the lasers, then use the dynamite on the exit door. The glasses pick-up reveals hidden platforms.
Shareware version — and the full game
This is episode one of three, the shareware release. Apogee's VENDOR.DOC, included in the package, encourages passing it on without charge. Episodes two and three are the registered game and are not hosted here.
