Here is the list of everything you'll be able to swap any item in inventory to. I'll provide food/water/health pack info too. As for specific gear/weapons/materials... I'll give just the naming scheme, I'm not going to map them. If there is anything else I might be missing that would be very useful, please let me know soon. I hope to get this guide done within the next 2 days.
