Just ahead of its return to theaters this Friday, the Tomb Raider series’ next game will be revealed tomorrow, March 15, at 9 a.m. ET. A waning crescent with the reveal details have replaced the official Tomb Raider website, hinting directly at the rumored title for the new game, Shadow of the Tomb Raider.

But while details are scant until the presumed reveal tomorrow morning, inspecting the website’s source code gives away much of the big news about Shadow of the Tomb Raider — including its release date, platforms and place in Lara Croft’s rebooted storyline. Users quickly discovered the info embedded in the website and took to Twitter to share it with fans.

The source code points at a Sept. 14, 2018 launch date for Shadow of the Tomb Raider, which is “the climactic finale of Lara’s origin story.” PlayStation 4, Windows PC and Xbox One versions are expected. There also appears to be a more detailed reveal event planned for April 27, when publisher Square Enix will discuss pre-order incentives, among other things. (Strangely, when the company said in December that a new game was in the works, it said there would be a shorter period between reveal and release this time around.)

We’ve reached out to Square Enix for confirmation of these details, although prominent placement in otherwise generic, Latin-laden source code seems pretty concrete. We’ll update accordingly — as well as cover tomorrow’s reveal. Meanwhile, Tomb Raider is in theaters March 16.
