Following Saints Row 4 ban, the Australian Classification Board has also banned State of Decay.
"We've run afoul of certain prohibitions regarding the depiction of drug use," Undead Labs' founder Jeff Strain posted on the game's forum. "We're working with [publisher] Microsoft to come up with options, including changing names of certain medications in the game to comply with ratings requirements. Whatever our path forward, it's going to take a bit."
A Microsoft spokesman also confirmed that the company " is currently evaluating the options with regards to the title's classification. The Australian Classification system plays an important role in ensuring that Australians can only access age-appropriate games and content."
"I know this is frustrating – believe me, we're frustrated too," said Jeff Strain. "But each country has the right to set its own rules about content, and it's our responsibility to comply with them. Rest assured we'll do everything we can to find a way to get the game into your hands."
