Paegaas Workshop Spiker

The Spiker is a Brute weapon in Halo 3, which fires bright orange spikes. It is a duel-wieldable weapon resembling a cut-down shotgun, with two bayonets. When the spiker is not in use, it can be seen holstered on your spartans hip.

This weapon was seen in the Behind The Scenes: Halo 3 Trailer video.
