We’ve learned the announcement of Just Cause 4 has been leaked ahead of its reveal next week at E3 2018.
The news comes via the News page of the Steam client (thanks, @Wario64), which leaked the game’s reveal via a “Pre-Purchase Now” image, which you can view above.
If you click through the image, it’ll lead you to its unpublished Steam page.
Square Enix, the publisher on the franchise, is likely going to announce the game during their E3 2018 press conference, on June 11th.
