Mastering the controls is paramount for effective stealth. Sam Fisher's movements are fluid and precise, allowing for a wide range of tactical options. Familiarize yourself with the default keybindings (PC) or controller layout (console) and consider customizing them for optimal comfort and responsiveness. The User Interface (UI) provides crucial information: the Light Meter indicates your visibility, the Noise Meter tracks your sound output, and the Health Bar shows your current condition. Pay close attention to these indicators to maintain your cover and avoid detection.
