Developer Iron Gate's recently-released Valheim has attracted more than two million people in less than two weeks.

That's according to a blog post from the studio on Steam, which says that the Early Access survival game hit this milestone within 13 days of its launch. That comes in the wake of the title hitting one million sales in its first seven days.

"Everyone at Iron Gate has really been appreciating all the messages, love, questions and thoughts from all of you, so please keep them coming," the studio wrote. "And again, a big thank you to all of you for helping us reach this ridiculous milestone in under two weeks of sailing onto Early Access."

Valheim has also been the No.1 selling game on Steam for the last two weeks, perhaps unsurprisingly.

Not only is it proving to be a bestseller, it is also one of the most popular releases on Steam,  According to data from SteamCharts, the survival title currently boasts the fourth-highest concurrent user count on Steam and has had a peak of 391,325 people playing at once. Iron Gate's title hit that particular milestone at 21:00 GMT yesterday (Monday, February 15th).

Already Valheim is up there with the likes of Valve's Counter-Strike: Global Offensive and Dota 2, as well as battle royale blockbuster Playerunknown's Battlegrounds.
