Loot is basically an item you find around the map. My original idea was that you have to grab all the loot, get back to the pickup truck and place it. You would then get in it a free yourself from the map. Brilliant! Well, the we came up with shops.
A shop you say? For what? Weapons?!
After getting some loot to trade, you can go to shop, maybe get a gun, ammo, some food, depending on what it's got. The different stores may have different prices as well.
Hopefully we can add some quests in to get specific loot for random villagers(yeah, there's going to be a village). This should be an awesome game when finished!
