Stealth is the cornerstone of Chaos Theory. Your primary goal is to remain unseen and unheard. The Light Meter is your best friend; always strive to keep it in the dark blue or black. Utilize shadows, turn off lights, and shoot out light sources to create cover. The Noise Meter indicates how much sound you're making. Walk slowly, crouch, and avoid running on noisy surfaces like metal or glass. Distractions, like throwing objects or using gadgets, can draw enemy attention away, allowing you to slip past undetected. Remember, a silent takedown is always preferable to a loud firefight.
