It shows a dark and stormy jungle in it’s ad.
Kotaku’s Luke Plunkett posted today that he received an ad for Just Cause 4 on his steam account, and Polygon has showed the ad appearing under Updates and Offers. We don’t know much about the game, only that it was leaked last month when Walmart pre-emptively published listings for it alongside Rage 2 and Lego DC Villains, both of which have been since confirmed and announced.
We can probably expect more information when Square Enix has it’s E3 press conference.
