How to Play Granny Chapter 3 High School
You explore the school from a first-person view, with your gloved hands and a narrow cone of flashlight light doing most of the work. Corridors, noticeboards and classrooms are almost pitch black, so you sweep the beam across walls, desks and doorways to spot pickups and doors worth trying. A health readout sits in the bottom-left corner and drops when you get caught out.
Progress comes from items: the keys that open the school's classrooms, and the revolver with its ammo. Inside a classroom you can find a lone desk marked with Granny's name and a key to a locked door. Press F to interact with anything you can pick up or open, and right click to fire once you're armed — a green health bar appears over Granny when you hit her.
When Granny or a Slendrina specter closes in, you either shoot or break line of sight and hide. On-screen prompts let you press I to check the controls and hold O to recheck your current objective.
Tips
- Keep the flashlight beam moving across desks and noticeboards — keys and ammo are easy to walk straight past in the dark.
- Check the classroom desk marked with Granny's name; it holds a key for a locked door.
- Hold O whenever you lose track of what you're doing instead of wandering blind and burning health.
- Ammo is limited, so save shots for when Granny blocks your route rather than firing at every noise.
- Watch the health number in the corner — if it drops low, break off and hide rather than pushing deeper into the school.
