Create "windows" that show players what's going on outside the room or building; require them to use this information to track progress or solve puzzles within the room. For example, if a zombie apocalypse is underway, allowing players to witness how the zombie's behavior is changing over time may provide clues to a puzzle. [Note: Even if the things players can see outside don't help them solve puzzles, it can add to the immersive quality of the room. For example, being aware of the increasing numbers of zombies outside the "window" can add a sense of urgency.]
