Blue Marine

The Blue Marine is a DLC submarine in Steel Diver: Sub Wars. It was released on June 2, 2014. It is a rendition of the submarine of the same name from Nintendo's Star Fox series, having appeared in Star Fox 64 and Star Fox 64 3D, the latter of which being the rendition that the Blue Marine is based on. It is the fastest submarine overall, so this sub is very hard to hit, but its low durability and dive/surface capability makes it particularly vulnerable in head-on battles.
