Guides
It is not a hard game to understand; it is a hard game to finish. Start with the loop, then the route out.
Beginner guide
What the game wants from you in the first five minutes, and the three things new players get wrong.
How to escape
The full route out of the school, and why it is a search problem rather than a map problem.
How to survive
Staying alive long enough to finish searching. Lives, deaths and what dying actually costs.
Controls
Sprint, slide, crouch, crawl, flashlight — and one prompt that may not exist yet.
