by all ground units. (Note that units inside a city of size 7 or more get no bonus from
Walls.) The Coastal Fortress increases the defense strength of all units within a city by
50% against naval attacks. The Coastal Fortress can also take shots at passing enemy ships.

Units within a Fortress gain significant advantages. A unit stationed within a Fortress
has its defensive strength increased by 50%, and it gains the ability to take “free shots”

is the Small Wonder SDI Defense.
Settlers and Workers
Settlers are groups of your most resourceful and adventurous citizens.As inde-
pendent pioneers, they perform a critical function for your civilization: they
found new cities. No other unit has this vital ability.
Workers serve as civil engineers, improving the terrain for your empire’s ben-
efit. At first, their skills are fairly limited, but as your civilization discovers
advances, they develop more talents and better equipment.
