Chaos Theory is the branch of mathematics that deals with complex systems in which even the smallest action can have huge ramifications. By the end of Life Is Strange's third episode, the player and the character's will know this all too well.
So far Dontnod's narrative-led interactive adventure has juggled a number of elements – it is part mystery, part supernatural thriller and part coming-of-age tale. Episode one, Chrysalis, set everything up with the second, Out of Time, cementing an identity for the series and its characters before reaching a powerful finale.
Episode three, Chaos Theory, explores the mystery side, with heroine Max Caulfield and her closest friend Chloe Price breaking into the high school around which the story has focused to search for clues.
