The survivors are beefing up their prison home on "The Walking Dead."
In the behind the scenes video above, comic book co-creator and series executive producer Robert Kirkman showed off the new digs. The living quarters have expanded, crops are growing and there are farm animals mingling with the zombies and survivors. There's also a new cellblock and more fence defenses.
"We're making everything look different and new and unique for this season. I think there's going to be some really cool new elements thrown in that will shock you," Kirkman said in an earlier "The Walking Dead" Season 4 video.
"The Walking Dead" premieres Sunday, Oct. 13 at 9 p.m. ET on AMC.
