"Shadow of the Tomb Raider is the climactic finale of Lara's origin story," the source code reads. "Available September 14, 2018." In addition, the code lists PS4, Xbox One, and PC as available platforms, which is intriguing given the most recent game in the series, Rise of the Tomb Raider, launched on Xbox One before coming to other systems. Moreover, a trailer for the title has been leaked on FaceBook.
According the source code, an official reveal is likely to take place in late April. Square Enix did reveal in December last year that a new Tomb Raider game was in the works: "Driven by our goal of putting our fans first, we want you to know that it won't be long between the official reveal and when you can play," read the company's statement. "Our journey will begin with a major event in 2018. We simply can't wait to take you on Lara Croft's defining adventure." If you want to check out the source code yourself, you can find it on the game's official website.
