Valve is a game developer and also the founder of Steam, and the Half Life series. Over the last decade, Valve has been denying Half Life fans from information on Half Life 3. Even so, the persistent rumours and leaks kept the fans believing that Half Life 3 is in production.
Now, it looks like the long wait is about to produce gold for the Half Life fans. Just yesterday, a new leak has surfaced on Steam. The desktop software form Valve was updated with App 323900 and it came together with Half Life 3’s logo.
The leak became viral instantaneously and it got Valve to remove the app from Steam. Regardless, the damage has already been done and the leak unofficially confirms that Half Life 3 is in production. This is because the leak came from Valve’s entity, Steam.
