Eldritch Instinct is an adventure game for one facilitator (the Warden) and at least one other player. Players act as curious investigators of the strange and unexplained. They will take on delusional cultists, hide from stalking shadows and face terrifying monstrosities.

Brace yourself for a blend of dreadful cosmic horror and adrenaline pumping action, where the players rather than their characters do the investigating. Uncover mysteries and acquire forbidden knowledge in a quest to foil the sinister Mythos agenda. Some mechanics take full effect in longer campaigns, but serve one-shots just as well.
