The Talos Principle is a philosophical first-person puzzle game from Croteam, the creators of the Serious Sam series, and written by Tom Jubert (FTL, The Swapper) and Jonas Kyratzes (Infinite Ocean). Players are tasked with solving a series of increasingly difficult and complex puzzles woven into a metaphysical parable about intelligence and meaning in an inevitably doomed world. This definitive version contains the original puzzler in all of its glory and the ambitious expansion The Talos Principle: Road to Gehenna.
