The hit AMC zombie drama unveiled a Season 8 trailer today at San Diego Comic-Con, and it starts off with Negan warning Father Gabriel that the latter is about to "s--- your pants." What follows is a lot of explosions, a hailstorm of bullets, and of course, hordes of zombies.

It's all-out war against Negan and the Saviours, with Rick and Alexandrians, Maggie and the Hilltop crew, and Ezekiel and his Kingdom all banding together to fight back. "Those who use and take and kill — we end them!" Rick yells.

There are glimpses of every major and sub-major character, the betraying Jadis and the Trash People, and at the very end, a cane and an older Rick! Is this a dream sequence? A flash-forward into the future?

"The Walking Dead" Comic-Con panel takes place this afternoon and may reveal some more details. Season 8 premieres October 22 on AMC.
