I found a pretty old thread on here that had the weapon ID's listed for the giant and shadows of evil but a lot of the codes were incorrect and it didn't have the newer maps so I decided to sit down for the next three and a half hours and get them all figured out. I hope this helps you guys. If you have any fixes you want to provide then please feel free to comment below with any errors you find in this list. I will keep this updated whenever I can.
