Last year Nintendo revealed that it was testing the free-to-play market with a sequel to its 3DS game Steel Diver, and today the game is finally launching. Dubbed Steel Diver: Sub Wars, the Nintendo 3DS game is free to download, but youll only get a small amount of content if you dont splurge on the premium version. Youll also get more missions and customization options by purchasing the full game — the free version essentially serves as a demo for the complete game, and there doesnt appear to be additional in-game purchases. Nintendo describes the game as a tactical FPS that features eight player underwater battles both online and locally.
