Zombie survival game State of Decay has some rather unusual "easter eggs." Developer Undead Labs has been preparing the game for a re-release including all of the DLC and boosted visuals. While dredging through the code, they discovered something unexpected though--countless images of penises.

Because the studio was pretty small when they first started work on the game, they relied heavily on contract work to fill out the open-world. It turns out that many of those freelancers hid embedded penises into the backgrounds. In an interview with XBLA Fans, Senior Designer Geoffrey Card said, "Some of our contractors worked a ridiculous amount of genitalia into the background."

These images aren't clearly visible in any publicly released version of the game, but scaling the visuals up to higher resolutions for the remake made them easy to spot.

A Microsoft spokesperson also commented on the matter saying, "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. 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."

In addition to removing tons of phalluses, State of Decay: Year One Survival Edition will improve textures, reduce object pop-in and generally make the world feel denser.

The new release will be available on April 28 for $29.99 on PC and Xbox One.
