In Chaos Theory, the night‑vision mode uses a striking “all‑white hot” visual style where heat sources appear as bright white against darker surroundings—this reverses the more common “black hot” palette and gives players an unusually stark, high‑contrast view that makes enemies, vents, and electrical equipment immediately pop out; mechanically, it also helps stealth gameplay by letting you spot targets and heat signatures through light smoke or low visibility environments without losing scene detail.
