Saber Interactive's World War Z has sold over one million units in its first week, according to a press release made available by Gamasutra through a collaboration with PR-related resource GamesPress.
The zombie survival game, inspired by the 2013 Paramount Pictures film, was unveiled during E3 2018 and launched last week. Since then, the title has attracted a myriad of positive reviews and Saber has admitted that they're actually surprised by how well it has done on PC.
CEO Matthew Karch has expressed delight over the game's reception but has also credited the Epic Games Store for World War Z's success while claiming that it's performing "way above expectations" on PC.
"Saber is extremely thrilled by the performance of the game on all platforms," he said as part of the press release. "On the PC specifically, we are performing way above expectations thanks to the support we have received from the Epic Games Store.
"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."
The game is available on PlayStation 4, Xbox One and PC. It's available for $34.99 from the Epic Games Store but goes for $39.99 for consoles, which could be why it has seen more success on PC.
World War Z, powered by Saber's dynamic Swarm Engine, pits players against hundreds of speedy zombies who are able to attack as a collective herd but also break off into several individual attackers.
Players are given six different class options, as well as an extensive arsenal of weapons, explosives, and traps. They can take part in four-player co-op campaigns in locations around the globe, including New York, Jerusalem, Moscow and Tokyo.
There's also a mode in which both zombies and human opponents can be taken on in Players vs. Players vs. Zombies (PvPvZ) multiplayer.
While the Epic Games Store may very well be responsible for the boost in sales, the game has done itself little harm with its actual gameplay and players seem to be enjoying it thoroughly, although there's still room for improvement.
