There are some spoilers here._ ##### ABOUT ANOMALY []({STEAM_CLAN_IMAGE}/25160263/6cdbfec4c03544d76eeb815d1acd91876f989937.jpg) []({STEAM_CLAN_IMAGE}/25160263/8557543962a9dc4a4e40500c9aaba49ed690a218.jpg) The expansion begins when your colonists accidentally provoke a mad superintelligence. From then on, madness manifests: Monstrous creatures, mind-bending mysteries, infiltrating parasites, and sanity-shredding phenomena that twist the whole world around you. Inspired by classics like _Cabin in the Woods_, _The Thing_, The Cthulhu mythos, _Hellraiser_, and many more, _Anomaly_ goes beyond fighting monsters. This expansion presents ominous, puzzling, mind-controlling, and earth-shaking threats to build your personal horror story. []({STEAM_CLAN_IMAGE}/25160263/04dca84ee98644a7daf834de3c8ca12a382dd24f.jpg) []({STEAM_CLAN_IMAGE}/25160263/c681eb21b599ef3e79d7d5f6e28f60396633170c.jpg) Some of the twisted scenarios you'll encounter: - At night, hear the screeching of a psychically-invisible hunter that feeds on human souls. Build proximity alarms to detect when it’s near, but you can only fight it when it chooses to reveal itself. Chip away at its health every time it returns, and collect and study chunks of its flesh. Turn the tables, become the hunter and kill it where it lives. - A massive flesh creature is growing across the landscape, consuming and covering the whole map with a quivering mass of meat. It defends itself with beasts and acid. Fight it to get samples of its nervous system, then study them until you can venture to its heart and kill it for good. - A parasite has mind-controlled some of your colonists - but who? They pretend to be human as they work to infest others. Track evidence, imprison, interrogate, and medically test people to find out who is infested before it’s too late. - A pulsating obelisk crash-lands near your base. You can try to suppress its filthy energy, but the obelisk may lash out and violently mutate your people, copy them endlessly, or abduct them to an endless gray maze. - Your colonists become obsessed with a beautiful golden cube, one by one. They build statues of the cube. They worship the cube. They love the cube. - A corpse arrives that looks exactly like one of your colonists - and seems to follow them. No matter what you do, the corpse returns… - And many more weird and horrifying events!

Use the monsters against your normal human and mechanoid foes where you can!
