Open world zombie game State of Decay has become the second game this week to be refused classification and banned from sale in Australia.
The Australian Classification Board refused the game for depiction of drug use, said executive producer Jeff Strain on the official forums.
Undead Labs is working with Microsoft Studios on measures to have the ban overturned, including changing the names of the drugs to something fictional.
"I know this is frustrating — believe me, we're frustrated too — but each country has the right set its own rules about content, and it's our responsibility to comply with them," wrote Strain. "Rest assured we'll do everything we can to find a way to get the game into your hands. Stay tuned."
State of Decay was released on XBLA in the US on June 5 and will follow on Windows PC later this year. It becomes the second game to be refused classification in Australia, after Saints Row IV, since an R18+ rating was introduced at the start of the year.
