Damage and repairs

Every building can be damaged and brought down. Walls, towers and machines have their own health (see Walls and machines). Other buildings have 40 health per tile, between 60 and 400, and a District Center has 2300.

Walls hold back water, so with Dam pressure on, a wall with too much water behind it takes damage and can give way like a dam (see Rivers).

Builders repair damaged buildings between jobs, starting an hour after the last hit. Construction priority decides which come first.

While a building is under attack you get an alert and a war horn.
