So... I have not gotten very far but I like the game quite a bit in the 3rd person perspective. The thing I'm having trouble understanding/figuring out is the crafting system. I understand you loot various items and you can then take that junk and turn it into stuff. However, I don't see much help (from the game) in telling me what these additions to my weapons actually do.

Any tips/advice in this area would be greatly appreciated.
