If you're looking for places to farm some materials for upgrading your gear, here are a few: Spinmetal: Skywatch in Old Russia. Because it's a smaller area, the Spinmetal is not only easier to find, but also more numerous. It helps if you've gotten the resource bonus from having killed a certain number of enemies, though. Helium Filaments: Anchor of Light on the Moon. They're located on the sides and near the bottom of buildings, and sometimes they're hidden in crevices behind rocks. Again, having the resource boost definitely ups your odds of finding some rather frequently. Do you have any areas where you've gotten lucky with material drops? Let us know!
