For completionists, Oni offers several challenges and achievements (depending on the platform/version). These often involve completing the game on higher difficulty settings, achieving specific combat milestones (e.g., 'Flawless Victory' for defeating a boss without taking damage), or finding all hidden items. Some challenges might involve completing a mission using only melee, or without triggering any alarms. Consult your platform's achievement list for specific goals. For PC players, community-made mods sometimes introduce new challenges or difficulty modes. Aim for efficiency in combat, explore every nook and cranny, and practice difficult sections to earn these accolades.
