Valheim is on a trajectory like nothing we’ve ever seen. The Viking-themed indie survival game has been shooting up the Steam charts, selling 3 million copies in an unheard-of 17 days. And people aren’t just buying it on a whim; they’re actively playing it, too. On Sunday, the game reached 500,000 simultaneous players, according to SteamDB, leaving the charred remains of four other all-time Steam player count records in its wake.
