As the name implies, it is a kind of bot whose weapons spin horizontally.
The most common weapons put on HS's are razor tips, iron spikes, and maces.
Trivia
HS's are very popular into the community now, and certainly the most built. All builders built at least one and a respectable amount of members do love them.
The stars include InfiniteInertia's Absolute Chaos (still undefeated), sage's Ultimatum, Starcore's Tempus fugit (pretty much of a legend into the lightweight division) and Fury (same in the MW division), and ACAMS's Death Warrant (did very well in the Tag Team Tournament partnered with Fury (this team was beaten by Sage and Sorrow)) and 2 Sinister.
