There is a fungus within your world; it multiplies and turns aggressive toward the world—will you be able to survive?
Notice: This mod requires a high-end computer. We are currently encountering errors with the "apocalypse" configuration mode; therefore, I advise against using this mode unless you have an exceptionally powerful PC, as a bug can cause millions of creatures to spawn in a single area. The mod now features natural spawning and new commands (all starting with `/flungus`). I hope you enjoy the mod!
Natural spawning is only present in more recent versions—specifically, the current beta, 0.0.2 or 0.2.0.
