Oniken: Unstoppable Edition is a 2D action platformer developed by JoyMasher, released in 2014 and available on PC, PlayStation 4, Xbox One, Xbox Series X|S, and Nintendo Switch. Drawing heavy inspiration from the punishing design of classic 8-bit action games, it places a strong emphasis on swordplay and precise movement as players work through gauntlets of enemies, environmental traps, and demanding boss encounters. The game deliberately channels the difficulty and aesthetic sensibility of early console action titles, prioritizing tight combat mechanics and challenging level design over accessibility. Players rely on both offensive technique and careful navigation to progress, with each stage presenting layered threats that require timing and spatial awareness to overcome. The result is a modern title built around the conventions and constraints of an earlier era of arcade-style platformers.
When a global war nearly decimated humankind, an evil military organization called Oniken takes advantage of the situation to dominate and oppress the few 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.
