Croteam, the developer behind the Serious Sam series, has announced The Talos Principle - a first-person philosophical puzzle game coming to PC, Mac, and Linux this fall. Announced at E3, the game has already garnered many best in show nominations and awards!
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 series of complex puzzles woven into a metaphysical parable about intelligence and meaning in an inevitably doomed world.
