Oniken: Unstoppable Edition is an action platform game developed by JoyMasher for the Nintendo Switch. The game is set in a post-apocalyptic world where an evil military organization called Oniken dominates and oppresses the few remaining survivors. However, a small rebel movement organizes strikes against Oniken, and a ninja mercenary named Zaku offers his services to the resistance for unknown reasons. The game is highly inspired by the 1980s, its games, and movies, which is evident in its graphics, sound design, and difficulty.

The game features six missions, each with three stages, and over 18 boss fights, including a boss rush mode. Additionally, there is an extra mission after you beat the game. Oniken: Unstoppable Edition offers a full pixelated violence experience that is not for the faint of heart. The game also comes with digital versions of the game manual and the original soundtrack, and global leaderboards for added excitement.
