A "room" is a technical term in Goldeneye 007.
Explanation
Each level in Goldeneye is divided into multiple "rooms." These are not traditional rooms as in a building, it's a programming concept for how the level is divided.
Guards within the same room and guards in a room other than the one Bond is currently in behave differently.
Which room Bond is in can affect where guards will spawn, e.g., Surface 1 and Streets.
