Mechanical Horseman

The Mechanical Horseman is in effect a Mechanical Axemen who must be killed twice - once to knock him off his horse and again to destroy the crystal in his chest. The horse only works when the axeman is sitting on top of it, and also tracks its target. It is more difficult to shoot at the crystal in the axeman's chest as the horse moves fast and also blocks a clear line of sight.
