Valheim's composer nearly delayed launch after writing a Doom-style boss track

Valheim almost missed its Steam Early Access release date in February 2021 because of a last-minute boss track crisis — and the composer had less than 48 hours to fix it.

Patrik Jarlestam, the game's composer, told the Audio Logs podcast that he sent Iron Gate Studio a draft combat theme for Yaglut — the fifth biome's boss — just three days before the platform's hard submission deadline. The track leaned heavily on Mick Gordon's industrial metal style from the Doom reboot. Iron Gate rejected it immediately: too much Doom, not enough Nordic fantasy. Jarlestam had to scrap the whole thing and write a new melody from scratch, mix it, and deliver it while stuck in strict Australian lockdown. The finished track landed in the developers' hands just three hours before the Steam build had to be submitted. Any communication delay that evening could have pushed the launch.

Valheim launched on February 2, 2021 and became one of the most explosive Early Access success stories in Steam history, selling over five million copies in its first month. Iron Gate is a small Swedish studio, and Jarlestam composed the entire soundtrack largely solo — which makes the tight turnaround even more precarious than it sounds.

The deadline crunch left marks elsewhere in the soundtrack too. Jarlestam ran out of time to record live instruments for the home theme, so placeholder virtual synths went into the final build — and stayed there permanently. It's the kind of detail most players never notice, but it's now part of Valheim's release history.
