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.
