Sea Tower
Project Rebearth wiki
The Sea Tower is a Defense building that extends a settlement's territorial vision on the water. It is the water-based counterpart of the Tower and must be placed on water.
Overview
[edit]The Water Tower costs 100 of the biome's primary resource to construct. In the Arctic it costs 100 
Wood. It requires 3 workers to operate.
Water Tower upkeep scales with the number built. The first Water Tower in a settlement costs 5 
Coin per day, the second 10, the third 15, and so on. The same scaling applies to the land-based Tower and is shared across both, so building two Water Towers and one Tower would result in three rising tiers of Coin drain.
The Water Tower has the same worker requirement as the land-based Tower but costs 2× as much to construct. It exists to defend stretches of coastline and harbors that a land-based Tower cannot reach.
Changelog
[edit]February 24, 2026
- Balance Towers and Sea Towers now have scaling upkeep: the first costs 5 Coin/day, the second 10, the third 15, and so on.
