'The Walking Dead' Season 4 Spoilers: More Death Than Any Other Season

What's for dinner? Brains. With the summer quickly dwindling down to its final golden days, fans of "The Walking Dead" buckle down and prepare for yet another gut-wrenching and thrilling season of their favorite zombie series. So what's on the horizon? Well, brains.

In an interview on the AMC blog, executive producer David Alpert hints that there will be even more blood soaked zombie killings in season 4 than previously seen.

"The great thing about this show is that literally every character is on the table... We have no one that is untouchable." Alpert said. "One of the hardest things was killing Shane. In the comic, it happened much, much earlier, and Robert has said he wanted to give that character a little bit more space to breathe. So trying to figure out what was the right place to kill Shane was really difficult."

"In the screening room here in production, there's a wall that says 'Our Grateful Dead,' and it's got pictures of all the characters who've been killed off over the seasons," Alpert said. "It's kind of insane. One, it's kind of touching, and, two, we've killed a lot of people on this show." Fitting for a series based in an apocalyptic zombie universe. "Oh, there's going to be a whole bunch of people added to the wall [in season 4]," he added.

Intriguing to say the least, but fans are still curious as to how they will be pinned to the wall. Will it be inner prison turmoil, or perhaps a mouthful of zombie treachery? "I think we're going to see an evolution in the walkers - there's a whole bunch of new walkers - and we'll see an evolution of the threat of human-on-human. Dangling the possibility of civilization will make people much more desperate and willing to do things that would have previously been unthinkable."

So fans will get the best of both worlds. More zombie chomping and more boiling tension amongst the survivors. It's going to be a wild ride.

"The Walking Dead" returns to AMC on Sunday, October 13.
