World War Z has sold an impressive 1 million in the week since its launch, with over a quarter of these sales coming through the controversial Epic Games Store. Saber Interactive announced the impressive sales figures before Epic Games waded in and congratulated the team on “selling over 250,000 units of World War Z so far on the Epic Games store!”

That’s not AAA figures but World War Z isn’t a AAA title, and for Saber Interactive this has got to go down as quite the achievement. WWZ peaked at 70,000 concurrent players during its opening week, although it remains to be seen whether it can cling onto this level of success long-term through content updates.

"Saber is extremely thrilled by the performance of the game on all platforms.  On the PC specifically, we are performing way above expectations thanks to the support we have received from the Epic Games Store” said Saber Interactive CEO Matthew Karch. “Moving forward, we’ll continue to work on growing the game and its community with new improvements, stability updates and bonus gameplay content, beginning very soon with a special new mission for the Tokyo episode.”

While we’ve got the sales numbers though, World War Z’s success on the Epic Games Store isn’t entirely quantifiable. We don’t know how well WWZ would’ve sold if it had launched through Steam, for example, so we’re all we’re left with is a theoretical comparison.

What the figure does tell us though is that a not-significant number of PC gamers are just fine playing a game bought through the Epic Store. It would appear it absolutely is a valid path for developers, despite the apparent widespread backlash to Epic’s way of doing things. It all contributed to a record weekend for the Epic Store. We’d love to know about more about how the likes of Metro Exodus, Anno 1800, and Satisfactory did as well, although it’s down to the developers/publishers themselves if they want to publish these numbers.
