State of Decay 2 will release on Xbox One and for Windows 10 PCs on May 22, Microsoft has announced.

The much-anticipated co-op open world zombie-killing survival game is an Xbox Play Anywhere title, so buying it on one platform gives you access to it on the other.

It's also a Microsoft-published game, so like Sea of Thieves, it will be available on Xbox Game Pass at launch.

The Standard Edition will go for AU$50, and the Ultimate Edition – which gives owners access four days early and includes two add-on packs and the digital version of State of Decay: Year-One Survival Edition – will retail for AU$70. New Zealand prices are yet to be confirmed.

According to Xbox, State of Decay 2 takes everything fans loved from the first State of Decay and creates a more dangerous and unpredictable world.

It features unique survivor characters with their own backstories and motivations, expanded options to manage your community and develop your base, and cross-platform co-op for up to four.

"Our goal is to build a long-term relationship with the State of Decay community and to foster deeper experiences with the franchise," said Microsoft GM of games marketing Aaron Greenberg.

"We believe State of Decay 2 accomplishes this goal by immersing fans in the ultimate zombie survival fantasy, and we want to give more players the opportunity to join in and experience this unique game.”

State of Decay was initially refused classification in Australia because it featured drug use.

It also didn't appear in New Zealand until a month after launch for unknown reasons, although at the time developer Undead Labs pointed the finger at publisher Microsoft Studios and the New Zealand government as possible culprits for the delay.

The game's drugs were relabelled from "stimulants" to "supplements", and it was finally made available as an R18 title in Australia.
