GR:Season 2 of Telltale's Walking Dead series might still be a ways away, but 400 Days is here to fill the hole in your heart that the first season left. And what does it fill it with? Well, more holes, as you might expect. That's sort of The Walking Dead's thing. The light downloadable episode only packs an hour-and-a-half punch and isn't really able to gain the emotional momentum that the first season did. That said, it's still a good stand-alone experience, and sets the stage well for the franchise's future.
