Polearm

The Polearm is a combo weapon in Dead Rising 3.

The combo weapon is described by the Official Xbox 360 magazine as:
 * "A variation on the spear-type weapons from previous Dead Rising games, Dead Rising 3's Polearm - spotted in the introductory video for Machinima's Xbox One Wingman app - looks considerably more deadly, owing to the additional pointy bits attached to its jabby end. The polearm is a nimble weapon, ideal for confronting more agile human enemies like Zhi, the murderous Buddhist monk. The same Machinima video also advises you to collect a Lone Blade book, which will boost a weapon's durability."

Release
Polearm was first shown in passing in the "Machinima app on Xbox One with Wingman" Youtube video on October 16, 2013.
