Fatshark's co-op action game Warhammer: Vermintide 2 has sold one million copies in the five weeks since its launch.

As well as reaching the significant sales milestone, the developer revealed that the game has racked up 5.8 million hours worth of Twitch watch time.

In-game 373 million items have been collected and just under 31.9 million loot chests have been received by players.

Vermintide 2 has been most popular in the USA, China, Russia, Germany and the UK.

Successive milestones

The title had previously taken just two days to sell 500,000 copies.

Fatshark CEO Martin Wahlund previously told PCGamesInsider.biz that by two weeks the game had already generated more revenue than its predecessor had during its lifetime.

Vermintide 2 is set to spread its wings from PC and land on consoles PS4 and Xbox One in the spring.

“We are genuinely humbled by the reception of Warhammer: Vermintide 2 from gamers all over the world,” said Wahlund.

“We reached half a million units within the first week, and one million within five weeks, which is far quicker than we ever expected.”
