If you already know the Borderlands 2 editor, you're 90% of the way here — but that last 10% is exactly where people trip. The Pre-Sequel uses a separate editor, a separate file, and a separate save folder, and trying to open TPS saves with the BL2 tool just doesn't work. Here's what's the same, what's different, and how not to mix them up.
- TPS has its own editor: bloz_saveedit_1.0.25.zip, from a different repo. Not the BL2 one.
- Saves live under BorderlandsPreSequel, not Borderlands 2.
- Keep the BL2 and TPS editors in separate folders, or they break each other.
It's a different editor entirely
Same author, same look, different program. Gibbed built The Pre-Sequel its own tool in a repo called Gibbed.BorderlandsOz — the "Oz" is for the Oz Kits, since the whole game takes place on Elpis where you need oxygen. The save files it makes carry a bloz_ prefix instead of bl2_. The BL2 editor can't read a Pre-Sequel save and vice versa — they're built for different save formats.
Get the right one
Download bloz_saveedit_1.0.25.zip (June 24, 2019 — the final release) from the Pre-Sequel editor's own GitHub. Like the BL2 tool it needs .NET Framework 4 and runs straight from its folder.
Grab the verified bloz_saveedit release (not "Source code"), extract everything, back up your save first. The whole safe-download playbook from the BL2 download guide applies here — just with the bloz_ file.
Don't mix it with the BL2 editor
The BL2 and Pre-Sequel editors ship conflicting versions of protobuf-net.dll. Drop them in the same folder and one (or both) will refuse to open saves. Keep each editor in its own folder and they coexist fine.
Where Pre-Sequel saves live
This is the difference that catches everyone — TPS does not share BL2's folder:
Note BorderlandsPreSequel where BL2 would say "Borderlands 2." Everything else is familiar: a numeric account folder, SaveXXXX.sav per character, a profile.bin beside them. Back up that folder before you edit, and watch the Steam Cloud conflict prompt just like in BL2.
What works exactly like BL2
If you've used the BL2 editor, all of this is muscle memory:
- Open with platform PC for Steam/Epic saves.
- Character, Currency, Backpack and Bank tabs behave the same — edit level, money, inventory, storage.
- Sync equipped items (or your whole backpack) to your Experience Level so the gear matches your character.
- Right-click an item to copy its code, duplicate it, or delete it.
- The same consistency rule applies: keep level and XP aligned or the game's sanity check reverts you.
Oz Kits, and the small stuff that changed
The one genuinely Pre-Sequel-specific thing in the editor is Oz Kits. They take the slot that Relics held in BL2 — oxygen rebreathers that double as your relic-equivalent, carrying bonuses to things like damage, fire rate and damage resistance. If you're hunting for "where are the relics," that's it: they're Oz Kits now.
Item codes follow the same idea as BL2 but use a BLOZ( prefix rather than BL2( — so don't paste a BL2 code into the TPS editor and expect it to take. The mechanics of pasting (one continuous line, no element suffix) are identical; see how Paste Code works.
When it breaks
The Pre-Sequel throws its own flavor of load errors — LZO decompression failures, SHA1 problems, end-of-stream crashes — and they have the same roots as the BL2 ones (wrong/old build, encrypted console save, corrupted download). I've put the TPS-specific fixes in Pre-Sequel load errors.
