Zen - Intergalactic Ninja (USA)

In Zen - Intergalactic Ninja, players control Zen, an intergalactic ninja tasked with protecting the universe from the pollution caused by the evil Lord Contaminous. The game combines elements of action, adventure, and puzzle-solving, taking place across various planets and environments, from polluted forests and oceans to cities and space stations.

Each level in Zen - Intergalactic Ninja requires the player to complete specific objectives related to environmental cleanup. Zen is equipped with a powerful Bio-Blaster, an energy weapon that can fire projectiles to defeat enemies and destroy sources of pollution. Additionally, Zen possesses special abilities such as wall climbing, high jumping, and dodging obstacles.

Gameplay typically involves navigating through side-scrolling or vertical-scrolling screens, collecting necessary items to activate cleansing mechanisms or unlock new areas. Players will face various types of enemies, ranging from mutated creatures caused by pollution to Contaminous's machines. Some levels also feature environmental puzzles, requiring players to think strategically to figure out how to clean up an area or neutralize threats.

Zen's health system is represented by an energy bar, which depletes when Zen is attacked or comes into contact with pollutants. Players can collect health-restoring items to sustain the fight. At the end of each major area, Zen will confront a boss, often a giant pollution-generating machine or a minion of Lord Contaminous, requiring tactics and skill to defeat.

A unique aspect of Zen - Intergalactic Ninja is its strong environmental protection message woven throughout the gameplay, encouraging players to consider the impact of pollution and the importance of preserving planets.
