Planet Rogoz after the sixth nuclear war. King Palestra's spies are reporting that Zak is going to kidnap the princess, and the elder counselor recommends that the king activates his secret weapon - you, a biorobot programmed to stop Zak.
Notes
Loosely inspired by the comic book Arnal a dva dračí zuby (Arnal and Two Dragon Teeth)
Given the plot, it's interesting that the loading screen is a Rambo III rip-off :)
