Get the full experience of The Turing Test with The Turing Test Upgrade Pack, which will give owners of the original game complete access to the extras contained in the Collector's Edition.

Included in the Upgrade Pack is the game's full digital soundtrack, alongside a PDF artbook containing imagery from throughout the game's development process. Not only that, but you'll also gain access to The Turing Test's first full playable prototype, so you'll have a unique opportunity to see how the game look when the Bulkhead Interactive team was creating the game itself. It's a rare chance to glimpse behind the curtain of the game-making process, so you can see how the game changed from prototype through to release.
