Solving Strategies
- Search before interacting. Walk around the room and check every surface before touching a keypad or switch.
- Read nearby documents. Codes are almost always written on something close to the puzzle, even if it is in another room.
- Listen and watch. Some mechanisms give audio cues or visual feedback when you are close to the correct input.
- Manage threat windows. The entity may patrol nearby. Solve in short, safe bursts rather than standing still for long periods.
- Save first. If manual saving is available, save before starting multi-step or timed sequences.
