This is a single player game being developed by the same group, Game Labs, that produced Naval Action. It is an offshoot of their successful grand tactical game Ultimate General Civil War.

UA: AOS will involve both land and sea actions at a fleet/squadron level as opposed to Naval Action where the player controls one ship. The developer is Nick Thomadis, Darth from Total War mods fame. Hopefully they will start beta testing soon!

They also have Ultimate Admiral: Dreadnoughts in the works for fans of early steel warships (1870s - WWI is the timeline I believe). Also a single player game.
