Blizzard's hero shooter Overwatch has passed another major player milestone. The developer announced on Twitter today that the PlayStation 4, Xbox One, and PC shooter has now tallied 35 million players since the game launched in May 2016.

The developer did not specify, but it seems likely that this figure covers the number of registered players across all platforms. Whatever the case, the game is growing, as the number of registered players stood at 30 million at the end of April. Overwatch reached 20 million registered players by November 2016, hitting that figure faster than any game in Blizzard's history.
