Oniken: Unstoppable Edition is a classic 8-bit style platform game developed by JoyMasher. Set in a post-apocalyptic world, the game follows the story of a ninja mercenary named Zaku, who offers his services to a small rebel movement fighting against the evil military organization called Oniken. The game is heavily inspired by the 1980s, which is reflected in its graphics, sound design, story, and difficulty.

The game offers six missions, each consisting of three stages, and over 18 challenging boss fights. The game also features cinematic cutscenes and an extra mission that unlocks after completing the game. For players looking for more of a challenge, the game offers a "Hardcore Mode" that increases the difficulty level.

Oniken: Unstoppable Edition also comes with a digital game manual and the original soundtrack. The game's graphics and sounds are reminiscent of the 8-bit era, which will take players down memory lane. The game also features global leaderboards, allowing players to compete with other players worldwide. However, be warned; the game is challenging, and players are sure to die numerous times.

Overall, Oniken: Unstoppable Edition is an excellent game for players who enjoy classic 8-bit style platformers and challenging gameplay.
