Barney became a powerful sentient AI ruling over Valve Software internally. Gabe Newell was pulled into the Prototype Source Engine forcefully by the rogue AI in 2003. Now he is only known as "GaB3N.exe" Only a 2-frame animated VTF file can stop Barney's corruption...CRAZY_LOUIS.vtf. Can Crazy Louis free Gabe Newell and save Valve Software from Barney's evil grasp before it is too late?
