The first update to Dungeons Deep is the Rotten Catacombs. This is a modular set with furnished and unfurnished pieces to build your own crypts, tombs and catacombs for your adventures.
This set comes with assets: music, sfx, soundscape presets, place-able objects, tiles and wall pieces.
As always this update is completely free, so if you own Dungeons Deep, just head to your launcher and download the update.
