I have no clue what this about but I’m loving it

It's based off of a video game called Dead by Daylight. It's a co-op game where there are 4 players playing as "survivors" and 1 player as the "killer" but some well known killers (such as freddy and Michael) are in there as well as a bunch of made up ones. You can read more about them the wiki. But it's fun if you're into horror games
