Mortal Shell 2: How to Get Unobtainable Mortal Shell 1 Weapons (PC Only)

After the latest patch, Mortal Shell 2 players can obtain three Mortal Shell 1 weapons through a specific method; before the patch, these weapons would not appear. Two of the weapons are basically fully functional except for missing audio, while equipping the third defaults to one of the other two. The weapons can be upgraded and infused with Tarstones, and their Tarstone special attacks and abilities work.
