However, the hit points of a tower are less than the hit points of walls built using the same amount of resources, so thicker and more numerous walls are generally preferred when possible.

In the late game, they can also be used to strengthen portions of walls where you know swarms will attack. This is particularly useful for defending 1 tile wide gaps where infected attacks will be highly concentrated at a narrow front and it will be difficult to get coverage from adjacent defenders or turrets owing to the narrow field of view. Towers do have high hit points for such a small building and thus can be used to strengthen walls in weak points.Against most opponents the two Great Ballista are both more effective and produce much less noise. This compares with the cost of two Great Ballista which has a construction cost of 1000 gold and 40 wood and a maintenance cost of 30 gold and 4 energy. For example, a 4 sniper wood tower has a maintenance of 28 gold and 4 food, and a construction cost of 1320 gold, 18 wood, and 8 iron. Although units in towers do make for very strong turrets, the construction and maintenance cost of 'turrets' made in this way can be quite high.Unfortunately, because of their attractive appearance and ready availability, newer players tend to make far more towers than they need and from an earlier point in the game than they need them, resulting in a lot of very pretty - but not helpful - newbie castles. Because of the relatively high construction cost of towers, and the fact that the leave your units passive, towers have only narrow uses in the game.

Wood Towers extend the watch and attack range of units inside by 3.

If a tower is destroyed, all units in it are deposited in the tile where it was destroyed. Wood Towers are the basic tower available from the beginning of the game. Units can be ordered to enter or unload from a tower and may exit from the tower on any unblocked side. Units in the tower cannot move or be attacked, but can still fire and do so with enhanced range on their attacks. Each tower can hold up to 4 units constructed in a Soldier's center. Towers are a supplemental defensive construction that temporarily allows units to act much like a turret. 'Units inside are protected and extend their watch and attack range.' General Information
