Valve's Source 2 resource file format parser, decompiler, and exporter.
Source 2 files usually files end with _c, for example .vmdl_c.
This repository is split into three components:
- CLI Decompiler - File data viewer, decompiler and a playground for testing new formats and features.
- GUI Viewer - A vpk archive viewer and extractor. Also supports viewing resources such as sounds, textures, models, maps, and much more.
- Library - Provides public API to parse resource files and some helpers.
⚒ You can download latest unstable build from AppVeyor.

- Model viewer
- Map viewer
- Sound player
- VPK viewer which supports opening and exporting files
- Read only VPK API
- Binary KeyValues3 parser
- NTRO support
This tool is based entirely on a reverse engineered effort because Valve does not provide any documentation or Source 2 code (SDK or engine code), while the Source 1 SDK and leaked engine code are helpful, a lot of systems and formats have changed.
The code contained in this repository is based on countless hours of reverse engineering Source 2 games and not all intricate details have been figured out.
