It will apparently tell a brand-new story and feature a new cast of characters, although also be based on Kirkman's long-running comic. It's expected to launch in 2015.
"Building on the success of the most popular show on television for adults 18-49 is literally a no-brainer," AMC president Charlie Collier said. "We look forward to working with Robert, Gale and Dave again as we develop an entirely new story and cast of characters. It’s a big world and we can’t wait to give fans another unforgettable view of the zombie apocalypse."
Kirkman said: "After 10 years of writing the comic book series and being so close to the debut of our fourth, and in my opinion, best season of the TV series, I couldn't be more thrilled about getting the chance to create a new corner of The Walking Dead universe."
