ABOUT THE GAME EKO: Chapter 1 is a free interactive mystery played inside the phone of Mira Vahl, a fictional woman who has been missing for three days. Players compare evidence, open locked material and decide how much to trust EKO. The clues, puzzle rules and solution are fixed. Conversations respond to what the player writes without changing the mystery's canon. GENERATIVE AI USE Character replies, images and voices use generative AI. Fixed rules control the evidence, relationships, progression and solution. EKO does not present AI generated dialogue as verified real events. CONTENT NOTE The game contains psychological horror and brief unsettling screen effects. Screen disturbances can be disabled in the sound and accessibility controls.
