So, from the moment you start playing, you're either the killer or a survivor. As a survivor, you have to scavenge for items and fix those generators to unlock the gates and escape. Meanwhile, the killer is trying to hunt you down and hang you on a hook for their dark lord to sacrifice.
The gameplay is all about stealth and strategy. You have to be careful not to make too much noise or the killer will find you. And when they do, it's a heart-pumping chase to get away. But even when you're hiding, you can still hear the killer's terrifying music getting closer and closer.
