In a report fromIGN, Saber Interactive has announced a GOTY edition ofWorld War Zand a Nintendo Switch version. Alongside the previously released DLC, the GOTY edition will come with a new third-person PvE episode set in the French city of Marseille and new weapons and character packs.

“World War Zhas had a huge impact on our studio in all respects. It feels fantastic to hit goals that perhaps a few years ago seemed unimaginable,” says Matt Kerch, Saber Interactive’s CEO. “We have over 10 million registered players that have played the game and our concurrent player counts are regularly in the tens of thousands. During our free week on the Epic Games Store 9.9 million people claimed the game and we peaked at 250k simultaneous users across platforms. The Epic team told me WWZ was the most successful free game on EGS yet - we even toppedLeft 4 Dead 2in terms of downloads and number of players.”

For those that don’t know,World War Zis a third-person co-op game that has you fighting swarms of zombies. The game launched last year and went onto sell overtwo million copies a month after its launch. The developer has also added cross-platform play on Xbox One and PC. Additionally, cross-play will be coming to the PlayStation 4 version later on.

In addition to the GOTY edition, a Nintendo Switch version is in development but there’s no specific release date at this time. Having portedThe Witcher 3to the Switch, Kerch says developingWorld War Zfor the Switch might be tougher.

“Keep in mind that we are rendering scenes with hundreds of enemies and four players online,” continues Kerch. “Getting this to run on the Switch is the hardest thing that we have had to do - this is true even though we are porting our own [Swarm] engine over to the platform.”

World War Zis available now on PlayStation 4, Xbox One, and PC. The game is also available through Xbox Games Pass. If you’re interested in the game, you’re able to check out its launch trailer below.
