Under Pressure
A Transhuman Space sourcebook about the oceans of the 22nd century, from Earth’s crowded seas to the subsurface oceans of Europa, Mars, and Titan. It covers ocean arcologies, mining operations, political and corporate claims, and terrorist threats in environments that challenge even spacefaring societies. The book includes aquatic character templates for parahumans, bioroids, cybershells, and uplifted animals, along with modular rules for designing aquatic vehicles compatible with the system in Transhuman Space: In the Well.
