ONE KILLER - a player or a bot - hunts everyone else in a dark building. EVERYONE ELSE has to find a way out before they get caught.

Items lie around the map: keys, a hammer, a key card, a crowbar... Press E to pick one up. You can only carry one at a time - Q drops it (or press E on another item to swap).

Some doors are locked: a padlock needs the key of the same colour, boards need the hammer, chains need the crowbar, a card reader needs the key card. Walk up with the right item and press E.

The exit needs a few items too (the top of the screen shows which). Bring each one and press E at the exit. When it has everything it opens - run out!

Press C to crouch: slower, but much harder to spot, and only crouching people fit through vents. The killer can't crouch and can't use vents.

Hide in a locker with E. The killer can't see you in there - but they can open lockers and throw you out, so don't wait too long.

THE KILLER swings with SPACE or a click. A hit catches someone. Press E at a locker to open it. Powers on 1-4: run faster, see everyone through walls, and put down traps that hold anyone who steps in them (and tell you where they are).

It is dark: you only see a little light around you. Survivors hear a heartbeat when the killer is close. If you get caught you are out for the round (the host can give more lives).

Phone: drag on the left side to walk, buttons on the right.
