In & Out

In & Out is a first-person puzzle game in which you investigate Project ISO’s experiments by combining clues in the game with knowledge from the real world. You study rooms, identify what information you are missing, research it outside the game, then return to test your discovery and choose an answer.

Project ISO

The experiments take place in a silent facility of cold, unfamiliar rooms. An artificial intelligence observes your decisions as you explore, decipher the tests and uncover its intentions. Recognising a reference is only the start: you must work out what it means in context and decide which answer to give.

Research and reasoning

Clues may be symbols on a screen or details you recognise but cannot quite place. You can consult a browser or a book, or ask someone who might know. What you do with what you find is up to you.

A shared investigation

In & Out is a single-player game, but you can discuss puzzles with a friend. Viewers can also investigate clues, identify references and question your theories while you stream; you make the final decision. A first playthrough takes around 3 hours, depending on your research, puzzle-solving pace and retries.
