The Ladder is a Seabase component intended to allow the player to climb vertically between adjacent seabase modules. They are constructed with the Habitat Builder and lower the integrity value by three units. They can only be placed on the floors and ceilings of modules where there is already another module in place ready to connect. Similar Ladders are pre-installed on the Cyclops and Lifepod 5.
A Ladder's placement appears to depend on the orientation of the foundation; currently, there is no way to choose whether a Ladder will be oriented north/south or east/west.
