Being a bit short on cash, I settled for watching a LP on Youtube. Wow, just wow. This game looks epic, and the characters are easily better than the show's,.
As for the sparkplug nonsense, which (I hope) confused others as it did me, here is the explanation. That whole sequence was the best part of the game, hope the other chapters include creative zombie-killing like that.
One of the most Tear Jerking scenes I've seen was in the game, at least, the way I played it. I initially protested the girl killing herself, but relented. I then stayed with her, and my final words for her were tear inducing: "I'm here with you now."
