Oniken is an action platform game available on Xbox One, immersing players in a retro-inspired world where they battle against the oppressive military organization known as Oniken. Set in a post-apocalyptic landscape, the game follows Zaku, a ninja mercenary who joins a small rebel group in their fight for survival. With a visual and auditory design reminiscent of the 1980s, players can expect a nostalgic experience that captures the essence of classic gaming.

The game features a total of six missions, each containing three stages, culminating in an extra mission for those who complete the main game. Players will face off against over 18 unique boss fights, with a Boss Rush mode for those seeking additional challenges. For those desiring an even greater test of skill, the Hardcore Mode offers a heightened difficulty level. Oniken also includes global leaderboards, allowing players to compete for the best scores while enjoying full pixelated violence and cinematic cutscenes.
