Descpription:
The single-player game consists of six levels. The ultimate
aim is to destroy a fleet of attacking ships while repairing any damage the fort sustains.
At the start of each level, the player chooses the location of their fort from a number
of options. This location is then surrounded by a wall to form a castle, which the
player can then place cannons within. After this, an attacking round commences,
followed by a repair round, where any damage to the castle must be repaired.
If the player manages to survive the repair phase, he is given a short
amount of time to place additional cannons within the walls of his fort
(if he made room for them), after which the battle resumes.
This cycle continues until either the player fails a repair round, or enough ships in the
enemy's fleet are sunk. When the opposing navy has been sufficiently depleted, the
level is won, and the player may then choose another level from the island map.
