Guys, instead of using Loki's Lost Key and Support call (wich glitches your UI) you could just get a debug console.
And then download/write scripts and just run them in there, scripts like:
Player addmagazine "Skin_camo13_DZ"
Player addweapons *
Player addbackpack.
You can use way more advanced scripts in there too. You could pop code from old cheat menus in there, and use those cheats that way.
