"A domed city rises from an inhospitable landscape. A linear-motor train waits for someone to board. L-ZONE! A hyper-automated city built by a mad scientist. Blinking control panel… a robot starts to move… the blast of a bazooka. Machine noise, white noise… noise, noise, noise. Clear the traps laid for you, pass through all the zones, only then will be unveiled that path to planet Green."
