Saber Interactive's co-op zombie shooter World War Z has sold a total of one million copies across PC, PS4, and Xbox One since its launch one week ago today.
Speaking to VentureBeat, CEO Matthew Karch said that World War Z peaked at 70,000 concurrent players over its first week, and players were distributed relatively evenly across PS4, Xbox One, and the PC release on the Epic Games store.
Karch also said the game is doing better than Saber expected outside the United States on the Epic Games store, with US purchases only making up one-fourth of total sales on the storefront.
"Saber is extremely thrilled by the performance of the game on all platforms," Karch said in a press release. "On the PC specifically, we are performing way above expectations thanks to the support we have received from the Epic Games Store."
In its opening week, World War Z debuted at the top of the UK retail charts, pushing out Tom Clancy's The Division 2, which had No.1 for three weeks total (two consecutive) since its own launch.
