This time it's the Earthless: Prelude which is a spiritual successor to the 2018 megawad Deathless - created by James “Jimmy” Paddock. Prelude is the first in a series of maps that will release over six episodes. The Prelude chapter contains two episodes and a "bonus" sneak peek at the third episode - adding up to 12 maps.
For more information about this latest add-on, there's a whole interview with the creator over on the official SlayersClub.
