What is a .BEPIS file?
BEPIS is a save file from the game ULTRAKILL, storing your progress as a .NET BinaryFormatter stream. Analyser decodes it into your money, weapons, level and difficulty progress, per-level ranks and Cyber Grind high score.
- Did you know
- ULTRAKILL, released in 2020, gives its save files the joke extension .bepis.
- Under the joke extension, an ULTRAKILL save is actually a .NET binary serialisation stream (MS-NRBF) with its bytes in little-endian order.
- ULTRAKILL was made by Arsi “Hakita” Patala and published by New Blood Interactive.
- What Analyser reads
- Read ULTRAKILL save files (BEPIS) - decoding the .NET BinaryFormatter stream into your actual progress: money and unlocked weapon variants, furthest level and difficulty reached, per-level ranks, secrets and best kills/style/time, and your Cyber Grind high score (wave, kills, style and time).
- Depth of analysis
- .BEPIS is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .BEPIS file
- Drag a .BEPIS file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
