"A manned heavy machine gun emplacement stationed high on an ocean platform. Capable of attacking land, sea and air targets it is the first line of most defences."


The Sea Fort is a direct defense against Naval Units.

A high rate of fire cannon causes heavy damage to any Air Force unit that strays into its path. Essentially a Machine Gun in the sea, the Sea Fort enables the possibility of having defensive cover against the enemy naval units. Clever placement of well promoted Sea Forts will cause havoc to unwitting attackers underestimating the defensive strength of the Sea Fort leaving their Naval units open to attack.

The Sea Fort takes up 3x3 cells in the game world and can only be placed on the sea.


The Sea Fort will become active and attempt to defend your island if any enemy attacking Naval unit such as the Gun Boat or Submarine come within range.

  • The Sea Fort's domain target is Naval, but is capable of defending against any troop unit.
  • The Sea Fort has 7 promotion levels.
  • Each new stage of the Sea Fort has a slightly upgraded appearance.
