Chapter 1: Awakening
Estimated Time
20-40 min
Difficulty
Low
Overview
The opening chapter introduces officer Jason Thompson and the body camera perspective. You will learn movement, interaction, flashlight use, and how the camera limits your peripheral vision. This chapter sets up the routine police operation that quickly becomes a nightmare.
Objectives
- Explore the arrival area and learn body camera controls.
- Collect any documents and supplies in the starting rooms.
- Reach the hospital entrance and trigger the next objective.
- Exit the prologue into the main hospital space.
Key Puzzles
The first puzzles are tutorial-level: find a keycard, unlock a door, or restore a light source. These teach the interaction and inventory systems without major punishment for failure.
Danger Areas
- Dark corridors without flashlight backup -- conserve battery.
- The first scripted entity appearance is usually a chase tutorial, not a death trap.
Collectibles
- Tutorial documents near the starting equipment.
- First optional note about the hospital lockdown.
Tips
- Move slowly and pan the camera often; the body camera hides threats in your blind spots.
- Pick up every document -- they often unlock achievements and puzzle hints.
- Save as soon as the game allows manual saving.
