Ubisoft's military-themed MMO shooter The Division is celebrating its second anniversary with the revelation that the game has been played by 20m people.

The French publishing giant doesn't clarify whether this is 20m copies sold or 20m accounts signed up to the New York-set online title, but either way it's an impressive milestone.

That's across PC, PlayStation 4 and Xbox One, by the way. There's no indication of what proportion of this playerbase is on PC. SteamSpy indicates 1.5m users on Steam, but of course Ubisoft's PC base is split with its own Uplay service.

In a tweet (below) from the game's official account, Ubisoft notes that 20m is twice the population of Sweden. Furthermore, half a million users had spent more than 400 hours in the game. Furthermore, engagement with the project increased twofold following the roll out of the 1.8 patch.

“We are very proud of what we have achieved during these past two years," creative director Julian Gerighty said.

"Listening and giving back to the community has always been our first objective and we would like to thank all The Division players for their valuable feedback and their support."

The title launched on March 8th, 2016. At the time, Ubisoft said that the game had broken its own record for Day One sales, with the French firm going on to say that the MMO shooter was its best-selling game.

If that wasn't enough, the game brought in $330m in its first week, an industry record at the time.

It would seem that The Division is another example of the games-as-a-service really working for Ubisoft. The other crown jewel in the firm's stable is 2015's Rainbow Six: Siege, which has been played by more than 25m people since its release.
