The Rotary Speargun[1] is one of the primary weapons used by both the Crab Suits and the Mako Submersibles.
Description[]
The Rotary Speargun is designed as a collapsible weapon fitted within the arms of a Crab Suit or the hull of a Mako Submersible.[2][1] It is able to fire a single speargun projectile - or multiple - at lethal speeds, nailing anything it impacts.[1][2] The weapon is reloaded through an internal rotary mechanism.[1]
The Rotary Speargun is used primarily for self-defense. The Crab Suit is able to mount two of them, one for each arm, whilst the Mako Submersible hides theirs within their hulls.[1][2]
