Announced officially Monday night at Sony's E3 press event, almost in passing, The Walking Dead: 400 Days is the next bit of downloadable content for Telltale's The Walking Dead.

As you can see above, IGN scored the exclusive trailer debut, but we do know a few details about the single-episode add-on coming this summer. First, 400 Days will be available on every platform the original episodic adventure was on, including the PS Vita. Second, the expansion will be included free in Sony's PS Vita Walking Dead bundle.

Telltale also released a few screenshots through its Twitter, showing off just a handful of the survivors we'll encounter during 400 Days. There's still no concrete release date in sight, but Telltale did state the game would be out in July. While pricing specifics haven't been disclosed either, it's hard to imagine Telltale asking more than the $5 (400MSP) the original episodes cost for this latest chapter.

Check out the screens below, and let us know if you'll be grabbing The Walking Dead: 400 Days when it arrives.
