Egregor also claimed to have obtained and encrypted data at Crysis developer Crytek, although it’s not clear the hacking group locked down the Watch Dogs material.
If authentic, the hack would primarily threaten the developers themselves if there’s any sensitive personal data. It might not necessarily hurt the game experience, though. As RPS noted, the source code might be most helpful for modders looking to tweak content or the game engine itself. It’s not clear if this would hurt the promised multiplayer update in December, though. There’s no guarantee a leak would include the online code, and it might change enough by the official launch to break any potential cheats.
