Just stumbled upon this : Fan made "DLC"
Not really news but seems it has not been discussed.
Plague Tale Requiem: Long Live the King Fan DLC | The Rookies
A Plague Tale: Requiem - Fan DLC level | The Rookies
You get a couple of videos, and they have made some posts on Artstation.
ArtStation - Plague Tale Requiem: Long Live the King Fan DLC
ArtStation - Plague Tale: Requium Fan DLC, Rishav Timilsena
It seems to have been some contest/project made by students. Pretty cool.
