NavyField is a free MMOTSG (Massive Multiplayer Online Tactical Simulation Game) that is based on World War 2 naval combat.
"NavyField pulled me in right away with it's wide selection of ships and weapons. Players will use victory to upgrade guns and at the same time watch their crew grow into specialized roles that give a ship most of it's personality. Players can maintain crew from multiple nations at the same time and can also have a pool of untrained recruits to draw from.
While NavyField is not a new game (there are US and Europe servers), the designers are adding new updates on the fly (including the introduction of French, Italian, and Russian forces). The designers are also working on NavyField 2. Above are some screen shots of me doing my thing."
