"The Walking Dead" star Lauren Cohan described the upcoming season six as "suffocating" and explained just how the characters will face their biggest challenges yet during an interview with Entertainment Weekly.

"I don't know if anybody has said this yet but we always joke that the writers write these amazing action sequences from air-conditioned offices," Cohan shared. "And I think this season is no exception and definitely rises above. We have the most suffocating beginning to the season that I've experienced yet."

"I think what's been really interesting is that you see us all kind of make strides in the direction of civility or civilization and a more regimented society," she continued. "And it's about being really challenged. So we'll see a ton of challenges and we'll see people the audience has been introduced to as very stable reliable characters crumbling, and I think it's going to be pretty scary. Welcome to 'The Walking Dead.'"

Based on the Image Comics series of the same name and created by Robert Kirkman, the sixth season of "The Walking Dead" is scheduled to debut with a 90-minute episode Oct. 11 on AMC.
