The Walking Dead‘s second webisode series Cold Storage has now been released in its entirety.

The series is exclusively available through AMC’s website and follows an entirely new set of characters — and zombies. The webisode series was directed by Greg Nicotero who is the show’s special effects guru and also directed another webisode series based on the hit zombie show last year.

We had first learned about this series last month. Cold Storage “tells the story of a young man, Chase (played by Josh Stewart), trying to reach his sister in the early days of the zombie apocalypse. He finds temporary shelter in a storage facility run by a former employee named B.J. (Roebuck); however, things are not what they appear.”

The cast includes Cerina Vincent (Cabin Fever) as Kelly and Chris Nelson (Kill Bill) as Harris. All four episodes can be watched for free below. Check ’em out and let us know what you think!

Meanwhile, The Walking Dead season 3 kicks off on AMC Sunday, October 14 at 9 p.m. ET/PT. One of the major new characters being introduced is Michonne, and AMC recently released a featurette on the character and actress (Danai Guruira). Guruira says of her character, “Michonne is somewhat to some extent self-taught, but she’s figured out how to make it economical, effective, and efficient.”

And she seems to really enjoy getting into character: “I love learning new physical stuff. It’s such an amazing craft, the katana…watching films and working with my trainer has been really awesome.”
