Viking survival title Valheim has managed to shift five million copies in its first month in the wild.

This new sales milestone was revealed by developer Iron Gate and publisher Coffee Stain, with the duo revealing that the game has been played for more than 15,000 years, while people have watched 35 million hours of Valheim on Twitch.

“Thanks everybody," Richard Svensson, the CEO of Iron Gate Studio said. "Your response is amazing and we’re excited to continue improving the experience, as well as adding whatever Odin compels us to!”

Coffee Stain Publishing boss Albert Säfström added: "Five million units is a huge milestone for any game, and to achieve this in four weeks is remarkable. We are incredibly proud to be by Iron Gate's side as they continue to make history with Valheim, and we too are looking forward to the Hearth and Home update."

Valheim has been the best-selling title on Steam for the four weeks since its launch. The game hit one million sales within a week of launch before hitting two million downloads by the end of its first fortnight. By its 16th day in the wild, the survival title had sold three million units and went on to hit four million sales by the end of week three.

The game has seen a lot of engagement, too, and boasts a record of almost 500,000 concurrent users on Steam.
