Deux ans. follows a conversation between a man and emergency services after an intrusion at the former's home - where he currently is. You play as the emergency responder, trying to diffuse the situation and help the man.
The game is full of tension from the first second of the "call", with a bit of a twist when the intruder can finally be "heard". With vague unsaid, you can imagine what happened two years ago (title of the game) - though it will never be explicitly revealed in the story. There are three endings - one I found more satisfying than the others (and which I got first!).
The game takes advantage of images to visualise the different callers, as well as uncomfortable background sound, to create a captivating and chilly ambiance.
