Press "Run" at the top of the screen then follow the instructions on the console on the right
This script takes inputs of your current hideout upgrades and completed tasks, then spits out a big list of all the items you'll need for 100% completion. Feel free to build on it or use as you like. Here's an example of my item checklist:
Notes:
- I haven't added the new 12.7 tasks yet
- Gunsmith tasks are ignored
- To copy the list you'll have to right click > copy your selection, since ctrl+C gives the console an error
- If you have a shooting range, it's level 1! Inputting 2 or 3 works fine too.
Stay organized boys.
