The third season of 'The Walking Dead' wasn't the most exciting season. But if this new trailer for the fourth season of the AMC show is any indication, it's going to be one of the best seasons yet. Check out the trailer that was released at this year's Comic Con.

As you'll see in the trailer, Rick, Daryl, Carl, Michonne and the rest of the group pick up where they left off - smacking around zombies and trying to survive. However, the group seems a lot more skilled and more organized. Plus, Carl is growing up to be an even more dramatic kid.

Each member of the group have different roles in keeping everything together, but soon walkers start making their way into the prison. Soon the group finds out someone let them in, and the debate is on as to who that might be. We do know that 'The Governor' is still alive and it could be him. One thing is for sure, there will be a lot more zombie killing than ever before.

'The Walking Dead' stars back up on October 13th.
