📋 About This Mod

This mini tool lets you add item serials to Borderlands 4 save files. Valid(!) item serials will be added to "Lost Loot" machine. Optional automatic backup.

Google Drive Mirror in case nexusmods falsely flags the .exe as malware until the mods review it ;)

By the way: Most of the time, this is due to unsigned files or "suspicious" activity, such as reading file contents...

BL4 Item Adder is a WIP tool for Borderlands 4 players with Steam save files.

It allows you to add item serials directly to your "Lost Loot" collection, giving you the ability to recover or manage special items without affecting your gameplay progress, as long as you have a valid item serial, such as @Uge9B?m/)}}$pj({w#6~q}oSQL!ihHQ2+ .

Key Features:

  • [](optional) Automatic backup of original save files before editing, ensuring your progress is never completely lost.

    []Safe decryption and encryption of .sav files, so you can modify them without risk. (currently only working with local Steam savegames)

    []Easy addition of item serials to the "Lost Loot" section - as long as they're valid.

    []User-friendly easy-to-use interface with guided actions for load, edit, and save.

    Experiment with new gear and have fun.

    Free updates incoming, as soon as we all know how to decrypt and encrypt item data within serials.

    Q: How do I restore a Backup, if I fk up a .sav?

    A: Delete the f*ked-up .sav file and rename the .backup file to .sav

    Q: Will this work with the EpicGames version of Borderlands 4?

    Q: Will this get me banned?

    A: Very likely not. Usually, Gearbox has been very "kind" to editing stuff like this, e.g. Gibbed, Willowtree

    Q: Can I create and edit items with this tool?

    A: No. Not for now. Until the community discovers a way to serial de-/encrypting.

    A: C#, . NET 4. 8, original decryption process from https://github.com/glacierpiece

    Q: Is there a way to edit backpack, bank, eridium, whatever?

    A: Not yet included, but there is a way, so the tool will be expanded.

    Q: SUPPORT PLX?????

    A: Not really able to, I have a life. Expect answers and updates SOMETIMES.
