"Engie's suicide.avi" is a obscure unused file in the Team Fortress 2 game, starring a RED Medic and a BLU Engineer. It appears on the surface to be an odd cinematic. Valve agreed to publically release the archive in the game, because the file is relative to a mystery involving a deceased employee of Valve. Witnesses had previously thought that the individual was a loose wire, ready to snap at any time. Watch at your own risk.
