One of the biggest things at Comic Con this weekend is obviously The Walking Dead and AMC dropped the first, extra long trailer for Season 4. When we left off, Rick and the gang had taken in the survivors of Woodbury after the Governor went nuts and killed his entire strike team. It seems like the group has built up a nice little community in the time between seasons as Carol is teaching the kids in the group about defense and there have been a number of upgrades the prison’s defenses, arsenal and transportation. There’s no sign of the Governor in this trailer but the immediate threat seems to be that the zombies are grouping and attacking in much larger groups than before. Check out the trailer below and season 4 begins in October on AMC.
