For the first time, PUBG is on sale on Steam. In celebration of combined Xbox and PC sales of "over 50 million units worldwide", the battle royale has a 33 percent discount from now through July 5.

Ahead of its Sanhok map launch this Friday, PUBG Corp has now also unveiled its 'Event Pass'—a "trackable progression-related system" that lets players unlock new content "in a way that is different from the crate and key system." It'll be rolled out alongside Sanhok on June 22.
