Devolver Digital announces a December 11th release date for The Talos Principle for Windows, OS X, and Linux, saying the PS4 and Android editions of this "mystical metaphysical parable" will follow in early 2015. They say preorders will commence later today on Steam, and will carry a 10% discount and will also include a free copy of Serious Sam 3: BFE, which will be giftable for those who already own a copy. Here's the quick pitch on The Talos Principle:

In The Talos Principle, players assume the role of a sentient artificial intelligence placed within a simulation of humanity’s greatest ruins and linked together through an arcane cathedral. Players are tasked with solving a series of increasingly complex puzzles woven into a metaphysical parable about intelligence and meaning in an inevitably doomed world.
