(IGN.COM) When Undead Labs began revamping its 2013 zombie-survival game with the upcoming  State of Decay: Year One Edition, the developer found a surprise in the game’s higher 1080p resolution textures that was concealed in the lower resolution version.

Undead Labs outsourced the creation of some of the textures and assets to contractors to assist with the original game’s development. The indie developer only discovered recently with the enhanced resolution and texture quality that the hired artists had designed penises into the game’s textures.

“Some of our contractors worked a ridiculous amount of genitalia into the background,” Undead Labs senior designer Geoffrey Card told XBLA Fans during PAX East.

 
The organs initially went unnoticed in the original release and got through testing because the game’s lower resolution textures kept them concealed. Undead began removing the phalluses from the game after the discovery and are no longer in any available versions of the game.

“Undead Labs was not aware of the textures in question until they began the process of exporting textures for State of Decay: Year-One Survival Edition, and they are not visible in the original edition of State of Decay,” a Microsoft representative said in a statement issued to IGN. “Undead Labs is no longer working with the contractor in question, and this material will not be present in State of Decay: Year-One Survival Edition.’”
