Intended Usage: If you copy / paste this guide, the spoilers will not be copied and you'll have a nice and easy checklist to compare against your current arsenal or which you can mark off as your obtain each item. You can then go back and look for spoilers to any items you are missing. I won't be giving source information for each and every single item, I'll instead be focused on things which the player could miss out on or otherwise won't be able to obtain until NG+ Please let me know if I need to tag any additional such items.

This guide was built from all the available information online compiled together and even then further added to with my own explorations. This guide is up-to-date with the base game; when DLC comes out give me some time to update it again. There shouldn't be any missing items, but if there is just let me know and I'll add them.

FYI when you kill a boss with a "hardmode" strategy, the normal weapon will always appear on some vendor for 0 tech scrap. So unless that vendor can refuse you service (Dr. Sorensson at Camp Bravo) you won't be missing out on anything by going for the v2.0 weapons.

If you need more specifics on where to find a given item I recommend this guide:
