Zombie-survival game State of Decay was revealed as being effectively banned from sale in Australia last week for containing "illicit or proscribed drug use related to incentives or rewards".
A special edition of the game has been submitted for classification, with the developer saying in the Facebook post, "Stimulants out! 'Supplements' in!"
Prior to resubmission, State of Decay's in-game medications consisted of both illicit and legal substances, which included methadone, morphine, amphetamines, stimulants, acetaminophen, ibuprofen, codeine, aspirin, "trucker pills", painkillers, and tussin.
Undead Labs also made reference to a PC release, saying the game will be on Steam, but "not soon".
State of Decay focuses on surviving in a zombie-infested world, and promises a dynamically generated experience that changes in real time.
Since its North American release, the game has sold over 500,000 copies on Xbox Live Arcade within three weeks, making it the fastest-selling original game on XBLA.
