Battle Fleet 2 is the radically improved sequel to the original and has kept the “Worms” / “Scorched Earth” style angle+power mechanic, but now features full 3D modeling of terrain, ships, and ship hit locations. Hit the the engines and cripple the enemy's maneuverability, or aim for the command center and disable the ship for an entire turn. Ships are more realistic in which weapon compliments they can carry, and ship control is more intuitive. Battle Fleet 2 also now features Fog of War, allowing for stealth tactics and surprise attacks to be a viable strategy as well as adding the importance of using ships and aircraft for recon as well as attacks. With a full featured campaign and a variety of single play scenarios, Battle Fleet 2 will keep even the saltiest of sea-dogs satisfied.
