Valheim, the breakout viking survival game from Swedish developer Iron Gate, has now sold over 2m copies in less than two weeks of early access release.
Valheim sets 1-10 players loose in a lushly lo-fi, procedurally-generated purgatory of dense forests, sparking oceans, and snowy mountain peaks, nudging them toward an eventual end-goal of reaching Asgard. Before that, though, there's a heap of co-operative exploration, crafting, building, and battling to be done, as players gradually assemble the tools required to defeat powerful ancient beasts (and construct pleasingly homely huts along the way).
Iron Gate launched Valheim into Steam early access on 2nd February, and its popularity quickly skyrocketed. It celebrated a peak of 160,000 concurrent players within its first week of release, and that's more than doubled in the days since, topping 367,000 concurrents as of today.
