Play new challenging variation of sea battle game: hide your fleet at big 20x20 sea field, then find and destroy enemy ships.
Now you have six new powerful battleships, they are bigger and have advanced weapons: every ship will fire to 4 squares at once and lose possibility of fire when sunk. Diagonal placement is now available!
The faster you destroy enemy ships the lesser damage they cause to your fleet and the bigger will be your GameCenter score.
