Each world contains a hidden 'Secret Chapter' that unlocks after completing the main story of that world and solving a specific environmental puzzle. These chapters are often more challenging than regular missions and feature unique enemy layouts or objectives. Completing a Secret Chapter typically rewards you with a significant amount of Power Orbs and a unique weapon skin. To find them, look for suspicious areas or interactable objects that seem out of place after you've finished the main story. For example, in World 1, you might need to push a specific block to reveal a hidden path. These chapters are excellent for grinding Power Orbs and testing your mastery of the game's combat system.
