Hollow Altar Rite Mod transforms your world into a tense survival horror setting with eerie creatures and reality-breaking events. It focuses on slow psychological pressure and strange sounds rather than unfair one-hit attacks or cheap jumpscares. The mod introduces a phase-based progression system where strange occurrences escalate as days pass. You must survive disturbing phenomena, build the hollow altar, and fight back against the darkness consuming the land.
