Borderlands 4 — Early Support
Borderlands 4 was released in 2025. The save format is similar to BL3 (SHA256 + protobuf) but the proto schema is still being documented by the community. This editor makes a best-effort attempt to read and modify fields. Always backup your save before using. Check the Proto Field Inspector to see raw field data.
