I was almost done with the skilled survivor achievement when the revolver showed up - level 5 with everything except rifle, which was at level four... I would really appreciate any tips for where to find books, ammo, and upgrading skills. While I am excited about the update, getting to level 5 with everything has been a lot of work. I am honestly bummed to be starting from scratch on a new skill when I have looted most of the world already... thanks for any advice you can provide.
