A scenario about a riot that has been defeated and it's leader will now retire to the east along with his personal guard and try and conquer a water fortress to be able to win back the riot... Multiplayer also : Yes
Not too bad; if you liked Water War by Adrian, you'll also like this one. Again, lots and lots of maritime mayhem, but no story, special ai/per, intro map or the like. Terrain map allows land units to oppose your navy, and you do have to kill a particular enemy unit and move your hero to a particular location. It's possible to win without killing everyone. Enemy presses your base early, but leaves you alone after that. Enemy can and does replace his losses for a while. Bottom line is - I like Water War better, but Water Fortress is OK.
