The Halberd is one of my favourite weapons of the game Chivalry (Chivalry: Medieval Warfare, for you heretics).
It has great damage, amazing reach and decent speed.
Watch this player simply destroy the opposition in free-for-all arena matches.
The only weapon used is the Halberd.
Like the Zweihander, the Halberd is only available to the Vanguard class (also one of my favourite classes).
