A huge trove of leaked internal Valve material has surfaced online, reportedly including a long-sought beta build of Portal 2 and files suggesting a weapon design intended for the never-released Half-Life 2: Episode 3. The find has generated significant excitement among Half-Life and Portal fans, since both projects have been subject to years of speculation, and the leak could offer rare insight into scrapped or unfinished Valve development work.

Beyond the headline items, specifics about the leak's overall size, its exact source and how it was obtained remain unconfirmed. As with earlier Valve-related leaks, the authenticity of the material and the full extent of what it contains have yet to be independently verified, so the claims should be treated cautiously pending further scrutiny.
