"Hunt or be hunted." That's the theme of the grisly new trailer for "The Walking Dead," which AMC released on Sunday ahead of the show's upcoming Season 5 premiere.

The ominous new clip promises plenty of eerie intensity and zombie goriness this coming season, and reminds us that death and danger are just around the corner for pretty much anyone. Even Carl.

At one point Rick tells him, "No matter what anyone says, no matter what you think, you are not safe. It only takes one second and it's over. Never let your guard down."

Yikes. Looks like nobody is safe this time around. We'll have to wait and see who makes it out alive when the AMC thriller returns October 8.
