DBD (aka dead by daylight) is an asymmetrical multiplayer horror game with 5 players (1 killer and 4 survivors) to put it simply the killers job is to well... kill, while the survivors jobs are to repair generators help other survivors and over all survive.

There are 7 generators of which 5 need to be repaired.

All survivors each have 3 healthy states (healthy, injured, dying) you can heal other survivors that are not healthy by simply standing near them and pressing the interact key (space, r1, rb).

When a survivor is interacting with a gen or healing another survivor they receive skill checks, Skill Checks are a Game Mechanic of Quick Time Events (QTE) that have a chance of appearing while performing various interactions.
