Valve recently suffered a massive internal data leak, with approximately 12 to 13 TB of Steam2 data being shared online.
Allegedly, files were extracted from an exposed, outdated public repository. The data spans ten years - from 2003 to 2013 - and includes builds, prototypes, and files of several popular Valve titles.
These titles include Left 4 Dead and Portal 2. However, a multiplayer game that was reportedly scrapped also features. Here's everything we know.
Valve Leaks Point to Canceled Multiplayer Scream Game
User @fellarobux took to X to reveal that they discovered a canceled multiplayer game after going through the Valve Leak.
The game, which is based on the Scream franchise, was made by Fatshark under Depot 42151. Fatshark is known for creating Escape Dead Island, the spin-off of Dead Island.
In the video, a player controls an individual wearing a black robe and a Scream mask. The aim of the game seems simple: one person is the Ghostface Killer, and their goal is to kill everyone. Those who aren't Ghostface need to beat the killer at his own game and expose them.
The user claims that there are a total of six versions in the leak. Although they didn't include download links, it would appear they can still be found online.
