Kredoos is a game built around assembling a samurai squad and battling through a challenging journey of 1,000 floors. Its dark fantasy storyline begins with the collapse of the old world, which is devoured by an oni. As the last warrior standing, players face the task of continuing the fight after time breaks just before the final strike. The game invites players to take up that unfinished battle and make the decisive move themselves.

The experience centers on squad-building, progression through the floors, and combat within this dramatic setting. Kredoos also features a game journey and a leaderboard, giving players ways to follow the adventure and compare their progress. The site provides an option to play for WL and prompts visitors to enter the game. With its samurai theme, supernatural adversary, and apocalyptic lore, Kredoos presents a focused action-game experience in which players lead their squad through a long climb toward victory.
