## Key points

- Alleged Valve leak claimed to include Portal 2 beta build
- Files reportedly hinted at a Half-Life 2: Episode 3 weapon
- Story fizzled out with no independent verification of claims

## Summary

A large cache of internal Valve material reportedly circulated online, with claims that it included a long-sought beta build of Portal 2 and files pointing to a weapon concept designed for the cancelled Half-Life 2: Episode 3. The story generated considerable excitement among Half-Life and Portal fans, given years of speculation about both unfinished projects, but ultimately no substantial new details emerged beyond the initial reports, and coverage has since died down without further developments.

Specifics such as the total size of the leaked cache, its precise source and how it was obtained were never confirmed. As with previous Valve-related leaks, the material's authenticity and full contents were not independently verified, so the claims were never moved beyond speculation.
