The Walking Dead: 400 Days, a DLC episode for the first season of The Walking Dead which combines five stories in a single episode, is available now for PSN (in North America), PC, and Mac. Xbox Live gamers can buy the game on the fifth of July, while European PSN will get the game five days later, on the 10th. iOS players don't have to wait long this time around, since it will be released for those devices on the 11th. The DLC is $4.99, except if you purchased The Walking Dead through the Telltale store, in which case you'll receive it for free as a thank-you for buying directly from Telltale.
400 Days is also coming to the PS Vita, in a package with the rest of the five episodes of The Walking Dead, in August.
