Zombie Cow has announced through a delightfully funny press release that their excellent (and educational!) side-scrolling shooter Privates will receive a free downloadable add-on, arriving around April 2011 on PC.

The DLC will bring a completely new adventure, with the campaign taking players through the the inside of a “gentleman’s bits.” The new content will also include additional gameplay mechanics, new enemy types, new locations, and a new player character. So don’t necessarily expect just more of the same.

If you haven’t played the game yet, why not? It’s available for free and you get to play as condom-hatted soldiers of cleanliness. There’s really nothing that should be stopping you.
