The Talos Principle Key

The Talos Principle is a first-person philosophical puzzle game from Croteam, the creators of the legendary Serious Sam games, written by Tom Jubert (FTL, The Swapper) and Jonas Kyratzes (The Sea Will Claim Everything).

As if you woke up from a deep sleep, you are in a strange, contradictory world, with ancient ruins and advanced technology. Tasked by your creator to solve a series of increasingly complex puzzles, you need to decide whether to trust or ask difficult questions.
