Slug Sub

The Slug Sub is an underwater vehicle used by the Regular Army.

Information

The Slug Sub is a small submarine used during the Second Mission. Unlike other slugs, it doesn't have a Vulcan equipped on it, rather relying on torpedoes. When it's resurfaced, the Slug Sub can fire homing rockets, which get replaced for depth charges when it submerges.

Trivia

The Slug Sub was most likely based on the Granvia from In The Hunt, as both submarines play very similarly.
