This allowed players to duplicate rare items, such as fully upgraded weapons, First Aid Sprays, and valuable treasures, essentially generating infinite resources out of thin air.

The game screams: “Your equipment is full. Overwrite current equipment? (Yes/No)”

However, the "Overwrite" bug—primarily occurring in and split-screen sessions—allowed a player to bypass the discard prompt under specific network lag conditions or button-input sequences. By rapidly confirming the "overwrite" command at the exact moment a partner was picking up or dropping an item, the game’s logic would fail. The result? You could duplicate weapons, ammunition, and healing items or, more infamously, overwrite a high-tier weapon into a low-tier slot , effectively deleting the original item but gaining infinite ammo for the new one in unintended ways.
