The Stampeder is an alien enemy cut from Half-Life 2. It never went further than the concept stage and was therefore never scripted. Nothing is known about its skills and characteristics, apart the fact that he was probably to stampede somehow. It is unknown if it was to have come to Earth through Xen.
