Informal poll, who plays the series on Vita? It seems like such a late addition platform that, coupled with its small-ish install base, a lot of people who wanted to play The Walking Dead have by the time the Vita versions keep coming out.
I guess that's why The Walking Dead: The Complete First Season is, "now available for Android-based devices via Google Play, NVIDIA Shield via TegraZone, and Amazon Fire TV and Amazon Kindle HDX via Amazon." Got to reach out to new customers. The second season will end up on all of these devices "in the near future" as well.
Those of you looking to score it on Vita, April 22 in North America, April 23 in Europe. You can buy episodes at $5 a pop or save 20% by going in for the season pass, which I assume everyone will do.
