Overview
Stay in the shadows. Listen for footsteps. Garrett doesn’t fight guards—he avoids them, pickpockets them, or knocks them unconscious from behind. Thief made stealth the core mechanic, not an option. Looking Glass created sophisticated AI, light-and-sound systems, and level design that rewarded patience over aggression.
