Lord Contaminous, the main antagonist, has devised a plan to destroy the Earth. It's up to Zen: Intergalactic Ninja , a skilled intergalactic ninja, to stop him.
The game takes players through various stages, each with its unique environment and challenges. The stages include oil, smog, dust, and dam areas, which can be tackled in any order before the final stage becomes available. Zen's arsenal includes a photon stick for defeating enemies, as well as a slide maneuver and jumping kick to navigate through levels.
Power-ups are scattered throughout the stages, allowing players to gain temporary invincibility or restore some of Zen's depleted energy bar. The gameplay has been streamlined compared to its console counterpart, with fewer stages and a simpler overall experience.
