Chapter 6 - What's In The Bag?
You (Lee) and Christia go on a journey and find a bag with 4 rifles, 1 automatic, 1 shotgun, and a revolver. You can choose what type of weapon you want but it doesn't really change anything since they all have infinite ammo.
Chapter 7 - Stay Close To Me
This chapter is started when the group sees "The Herd" and if you aren't familiar with a herd it's basically a group of 250+ walkers traveling shoulder to shoulder. After seeing it Lee looks at Clementine and says "Stay close to me..." The action starts as you fight off Walkers while constantly moving with your group trying to escape everything. There are times where you have to choose to help your survivors fight and there are parts where you even have to choose between 4 different people and it's hard to tell what's going to happen with rapid surprises and who's holding themselves in battle and who's not.
Chapter 8 - What Remains
This is when you have your final outcome of survivors and when you make your hardest choice. I'm not going to ruin this because this is something everyone should really play for themselves and I feel bad for reading it before I played it. There is not really tons of "endings" but it was still amazing to just read.
