Valve's 12 TB 'Steam2 Teraleak' Exposes a Decade of Internal Builds, Including Early Portal 2 and Possible Half-Life 2: Episode 3 Files
A 12–13 terabyte archive pulled from a publicly accessible Steam2 endpoint is being called the largest leak in Steam's history, surfacing early Portal 2 builds, Counter-Strike: Global Offensive prototypes, and a Weaponizer model previously linked to Half-Life 2: Episode 3. Valve has not yet issued a public statement.
