Afterlands takes place directly after Cyrgoth's Revenge. You take the portal from Cyrgoth's Dark Acropolis as it begins to collapse, and find yourself in the heart of his final realm. You make your way through an underground aqueduct that leads into a cave. Upon spotting your first enemy, you prepare yet again for another long journey through hostile territories.
Afterlands is a 10 Level Single-Player Hub which is a sequel to Cyrgoth's Revenge. It is designed for GZDoom and Zandronum, and utilizes no new assets, meaning compatibility with any Hexen gameplay mod. While being Single-Player oriented, Afterlands can also be played in Co-op and Deathmatch modes, however due to the large map sizes, the latter is discouraged. Like in it's predecessors, there are numerous unmarked secrets throughout the span of the Hub, as well as two secret levels, one you can access early in the game, and another that is accessible towards the end of the WAD.
