SyFy has canceled zombie drama Z Nation, according to producer David Michael Latt, who posted a Twitter video announcing the decision.

Z Nation will end with its fifth season. The drama concerns a band of zombie-apocalypse survivors attempting to get a man who has an immunity to the virus causing the zombie explosion to the last-known Centers for Disease Control research lab in California.

“We wanted to tell you face to face … that we were not renewed for Season 6,” Latt said in a late-night Periscope video on Friday. “We’re stopping at Season 5. We’re very sad, but we’re also really grateful with the opportunities that we had on the show.

“This is not the end of anything,” Latt added. “This is just the beginning of a lot of things.” i

Z Nation was created by Karl Schaefer and Craig Engler and produced by The Asylum. The show premiered in 2014 with 13 episodes.

Netflix has already picked up a prequel series, Black Summer, which has an eight-episode order. The story concerns a mother searching for a daughter after the world collapses.

Z Nation‘s cancellation means its run ends at 68 episodes, with the season finale coming on 9 PM Friday, December 28.
