Them Dixon Boys sure seem to find themselves in heaps of trouble all of the time and they don't even have to be walker-related issues. But rest assured that this trailer for The Walking Dead: Survival Instinct's Walker Herd downloadable content is rife with the undead.

Zombie fans who pre-order the game at GameStop will get access to the DLC pack, which includes a Herd Mode that challenges players to survive against waves upon waves of the undead. Yes, Herd Mode is basically a Horde Mode, but what's not to like about an endurance test against zeds?

The pack also includes goodies for you to use in the single-player campaign, such as a survival knife, sawtoothed machete, kukri, reinforced hatchet, and an advanced machete. We're hoping the advanced machete will just do the work for us and have some kind of lock-on mode that aims for walker necks. Wait, that's not what "advanced" means? Darn.

Check out the trailer below, courtesy of Machinima, to see the Dixon brothers in action and to get hyped for the game's release on March 19th, 2013 for PlayStation 3 and Xbox 360. The Wii U version will come out on March 26th, 2013.

Let us know what your weapon of choice would be during the zombie apocalypse!
