Zen: Intergalactic Ninja

A Game Boy action platformer based on the eco-themed comic book character. Players control Zen through twelve levels spanning environmental disaster zones, fighting pollution-themed bosses and completing recycling bonus rounds in an isometric perspective with multidirectional scrolling.

Zen, an alien superhero turned eco-warrior, is dispatched to Earth to retrieve a buried geocrystal. Upon arrival he discovers that Lord Contaminous, a villain spawned from generations of pollution, plans to destroy the crystal and plunge the planet into environmental catastrophe. Joined by Jeremy Baker, Earth's destined "starchild," Zen must battle through disaster zones of acid rain, toxic venom, burning oil rigs, and plutonium mines to stop Contaminous and save the planet.
