Here's the latest from the laboratory of the self-proclaimed mad scientist of Steel Diver: Sub Wars:
This submarine's crew members leave her stats untouched from the base stats, which means that this submarine has a surface speed rating of 9. To take advantage of this, I also have this submarine where she can heal on the surface. That's not where this submarine shines, though.
I have arranged the crew of this girl to make her a master of reconnaissance. The plan is to remain still to avoid sonar (and surface quickly and run if needed), use the extended sonar range to tell when an enemy might be coming for me, and, perhaps most importantly, 1) Radio to my allies friendly positions to facilitate regrouping, 2) Use process of elimination or even the extended sonar range to radio enemy positions, 3) Use the Spy to also identify enemy submarine positions.
Unfortunately, I do not get experience rewards for performing recon, but it's still highly effective with a smart team, the long range torpedoes are a bonus, and this would be a dream machine for local battles or if this game ever got a competitive scene.
