Each mission in Chaos Theory has primary and secondary objectives. Completing primary objectives is mandatory for mission progression, while secondary objectives often provide additional story context or unlock bonus content. Your performance is graded based on several factors: detection count, alarms triggered, enemies killed (especially non-targets), and mission time. A higher stealth rating is achieved by minimizing detections and alarms, and by using non-lethal methods. Aim for a 100% stealth rating for the ultimate challenge and to unlock special rewards. Always check your objectives before proceeding.
