Rage

In each city there will be a shop of sorts where you can purchase upgrades and ammunition. All of the strange items you may find along your way can be sold at these shops. Be careful what you sell though, as some of these items can be used to make helpful items. While shoes can’t be used for anything other than cash, there are plenty of other things that can be used to make useful items. A bunch of rags can be used along with some antiseptic for a nice little health boost, and those are always handy.
