Oniken

When a global war nearly decimates humanity, an evil military organization called Oniken takes advantage of the situation to dominate and oppress the remaining survivors. Even though any resistance to this organization seemed hopeless, a small rebel movement organizes strikes against Oniken. One day, a ninja mercenary named Zaku offers his services to the resistance for unknown reasons. His moves are lethal and now he is the resistance's only hope. Oniken is an action platform game highly inspired by the 1980s, its games and its movies. You can see this not only in the graphics and sound design, but also in Oniken's story and difficulty.

In a post-apocalyptic future where global war has nearly wiped out humanity, the survivors live under the iron rule of the Oniken, a merciless cybernetic army. A small resistance led by General Zhukov fights to hold the machines back but is steadily being overwhelmed. Desperate, Zhukov turns to Zaku, a legendary ninja mercenary with a mysterious past who is said to be the only one capable of stopping the Oniken, and Zaku agrees to join the fight against the robotic legion.
