The Water Chamber is an aquatic counterpart of the Creature Chamber. It specialises in the creation of swimming and amphibious creatures, and once built allows the player to create amphibious creatures at the Creature Chamber too. The player may build multiple Water Chambers if they wish to speed up unit production.
The Water Chamber can only create a creature if its appropriate research level has been unlocked. For example, research level 3 must be completed before level 3 creatures can be created. Creatures of higher research levels typically require more time to create.
