'Comic-Con': Watch the Bloody 4-Minute 'Walking Dead' Season 6 Trailer

— -- The season 6 trailer for "The Walking Dead" starts off with Rick trying to move past his demons.

And it quickly turns into a battle between two factions.

AMC just dropped an epic, 4-minute trailer after the "Comic-Con" panel to promote the new season, which comes back on October 11.

The very long trailer shows Rick reuniting with an old friend from Morgan.

"I don't take chances anymore," Rick tells him.

"Then you shouldn't," Morgan replies, later admitting he has to stop Rick.
