A new expansion is now available for acclaimed first-person puzzler, The Talos Principle

According to developer Croteam, Road to Gehenna is a massive add-on that will take experienced players through some of the game’s most advanced and challenging puzzles yet.

“Players will return to a strange, hidden part of the simulation as Uriel, Elohim's messenger, and attempt to free the souls trapped in this mysterious place,” it said.

“The ambitious expansion includes over 20 new complex puzzles with hours and hours of thought-provoking gameplay, sure to challenge even the most experienced The Talos Principle veteran.”

To celebrate the expansion’s launch, The Talos Principle is 66 percent off this weekend, bringing it down to a mere NZ$16.
