A Steam leak exposed 12 TB of files containing complete games, betas, and prototypes published between 2003 and 2013
One of the findings corresponds to a version of Left 4 Dead created several months before its release.
This build features a different HUD, voice lines that ultimately did not make it to the commercial version, and sections of the maps that were modified later.
Due to the size of the files, there is still a large amount of information to review. The material could allow for the discovery of more early versions, prototypes, and unpublished content from games released during those ten years.
Steam suffered a leak of approximately 12 TB of data that includes files published between 2003 and 2013.
The material would include complete games, beta versions, and unreleased prototypes of titles that were published on the platform during that decade.
According to content creator related to Valve Gabe Follower, the data would have been collected through a public access endpoint. The process, according to his report, would not have required hacking.
The information would cover practically the entire Steam library between 2003 and 2013, and not only games developed by Valve.
The cutoff in 2013 would be explained by the change in storage system made by Valve that year.
