Dead by Daylight x The Witcher Collaboration Coming
Dead by Daylight, The Witcher and Five Nights at Freddy's will release collaborations.

Dead by Daylight, the multiplayer survival horror game, is celebrating its ninth anniversary. In honour of the anniversary, The Witcher and Five Nights at Freddy's collaborations will be added to the game!
The main villain of the FNAF series, Springtrap, will be added to the game as a new killer as part of the co-operation. We will continue to learn more about the character's abilities in the future. But for now, we know that there will also be a Yellow Rabbit costume for the character, inspired by the film adaptation.

About Dead by Daylight x The Witcher Collaboration
Another collaboration coming to the game as part of Dead by Daylight's ninth anniversary celebrations will be with The Witcher series. However, unlike the FNAF collaboration, Geralt will not be joining the game as a new killer, but as a costume. In addition to the Geralt costume for Vittorio Toscano, there will also be Yennefer, Ciri, Triss and Eredin costumes. The Witcher collaboration will begin on 3 June 2025.
