In Slender FortressEdit
The Horseless Headless Horsemann (HHH) is a Halloween boss. He can be stunned, and he takes a few hits before killing most classes. He makes the same sounds as he does in the regular game, so it may be easy to recognize, HHH can get faster than longer he chases, so outrun him and fast!
On some servers, The Horseless Headless Horsemann has a much bigger and hulk-like model.
