Darkness stirs on the rim. Survive flesh infestations, cultist attacks, shambling undead, blood rains, invisible hunters, and other sanity-shredding perils. Capture and study entities to harness the power of the void. Conduct psychic rituals and awaken an evil machine god.
What makes it special out of curiosity? The last few DLCs added mega mechanic changes and additions. This one looked like a glorified mod to me:X?
