Mr. Valve



Mr. Valve, also known as The Valve Guy, is the mascot used by Valve for their introductory logo, first appearing in 1998, for Half-Life.

Overview
He originally appeared as a model in a demonstration map created by Valve to showcase the GoldSrc engine abilities, which was also to be used as the actual introductory logo for their games. During that demonstration set in some sort of forge/workshop, a bald bare chested man with a goatee and trousers, is implanting a valve into his head with a machine.

The real time introduction was eventually replaced with an .avi video showing a static yellow-brown portrait of Mr. Valve, an actual photograph modified to include the valve.

In 2007, the original Mr. Valve was replaced by a heavily-built man with his back turned, and the valve now in the back of his head.

The map used in the demonstration is simply named "valve.bsp", and the model "mrvalve.mdl". Only one other model is used in the map: "spiggot.mdl", the valve itself. "mrvalve.mdl" can be found in the Half-Life: Day One model files.
