The FPS hit of 2016 has something to celebrate; it currently has over 20 million users playing the game with registered accounts.

Activision Blizzard announced today that Overwatch has passed 20 million global players. This news comes just under five months after the game’s release, and a little over two months after the developer announced the game supassed 15 million total players.
It’s worth noting this means there are 20 million registered Overwatch accounts, not necessarily that the game has sold 20 million copies. While Blizzard hasn’t released sales numbers for Overwatch, it was June’s highest selling game, according to the NPD’s numbers.

This is great news for Overwatch, as it ensures it will continue to get new content over the course of it’s life cycle.
