Eldritch Instinct is an adventure game for one Warden and one or more players who act as investigators of the strange and unexplained. As a player, you will take on delusional cultists, hide from stalking shadows and face terrifying monstrosities.

Brace yourself for a blend of cosmic horror and adrenaline-pumping action in which you do the investigating, not your character. Hunt down forbidden knowledge in your quest to foil the sinister Mythos agenda.
