Naughty Dog first spilled the beans on its post-apocalyptic action game, The Last of Us, in one of our exclusive cover stories. Since then, the developer has been quiet about how protagonists Joel and Ellie will interact with the fungus-infected enemies of the game. This new gameplay footage and batch of screenshots shows off more of the mushroom-headed foes than ever before.

Watch the trailer below for a glimpse at the tension and suspense that comes with creeping through a dark building filled with the fungal enemies. Beware, the video contains harsh language and gore.

For an even closer look at the game, check out the gorgeous screenshots in the gallery below. The Last of Us arrives exclusively on the PlayStation 3 on May 7, 2013.
