"Everything" uploaded to Steam during the legacy Steam2 period (September 2003 to early 2013) prior to SteamPipe (13 TB).
The dump, called the Steam2 Content Server Dump, was shared on August 29, 2026.
This even includes test depots, not to mention any prototypes that may exist both in test depots and those that store retail builds.
It's worth noting that not everything that existed can be obtained, such as some prototypes from Just Cause 2.
