The Walking Dead's second season is nearing its half-way point and has already seen some fantastic undead specimens. And while there are surely many more to come, now you can check out some of the best, most grisly walkers in this new photo gallery. Check out the gallery now (preferably not immediately before or after eating a large meal), then come back throughout the season to see the latest gruesome spectacles courtesy of Special FX guru Greg Nicotero and his KNB EFX team.
