Loved this game, played it to 100% completion on the PS4-Pro quite recently. You definitely want to look at the condition of the weapons - Mil Spec for the Drifter Crossbow is way better than the Junk spec one. The best weapons in the game are the Mil Spec or Special Forces ones. Also, quick tip about melee weapons - upgrading one resets its durability, so if you have the parts to upgrade one get a few good swings in before you upgrade it to avoid wasting scrap. Second tip...you can use your flashlight to attract freakers or other humans if you're hiding in a murder bush. Switch it on then off as soon as they take notice and start to approach. It's a really good way of drawing them close, along with throwing rocks.
