Approximately 12 TB of archived data from Steam’s servers has been leaked online. Valve’s materials from 2003 to 2013 have been made publicly available, including early versions and internal builds of the company’s games.

The leak includes data on early versions of Portal 2, Left 4 Dead, Counter-Strike: Global Offensive, Dota 2, and F-Stop—a canceled project related to the Portal series. The community is also examining materials that may pertain to Half-Life 2: Episode Three. In addition to Valve’s games, the archive contains builds and materials from third-party developers. Researchers have already found data on several projects in the Sonic the Hedgehog series. 

According to preliminary information, the leak did not result from a hack. The archive was accessible via a public access point linked to the outdated Steam2 system, which Valve used to deliver and store game content from 2003 to 2013.

Earlier, Valve updated the internal dollar exchange rate on Steam: $1 now equals 85 rubles instead of the previous 76. As a result, the cost of in-game items and goods in Counter-Strike 2 has increased. The “Arsenal” pass has risen in price from 1,225 to 1,360 rubles, a case key from 191 to 212 rubles, and regular capsules from 76 to 85 rubles.
