Valheim may just be offered in Early Access right now, but that hasn’t stopped it from turning into one of Steam’s biggest video games, clocking up a peak of almost 350,000 concurrent players in simply 2 weeks.

As revealed by SteamCharts, currently the Norse fantasy game is presently more popular than multiplayer favourites like PUBG, Apex Legends, and even Grant Theft Car 5, with only Dota 2 and Counter-Strike: Global Offense presently sporting more concurrent players.

Valheim has actually offered over 1m copies in simply a week. The Viking-themed survival and crafting game launched as an Early Access title on 2nd February, and quickly rose to the upper echelons of Steam and Twitch.

Valheim developer Iron Gate is advising all gamers backup their characters and worlds after discovering a “world-destroyer” bug is resetting development.

In a tweet, CEO Richard Svensson described how gamers can make backups and prevent losing their data to the bug, verifying that regardless of trying to reproduce it and address the glitch, the group hasn’t yet had the ability to do so. Nevertheless, Iron Gate presumes it might be linked to exiting the video gaming by ALT+F 4 and not via the menu.
