Also included are devices called "Psionic Amps" that can be used to create strange effects on the player or on the world around them - e.g. one type of Psionic Amp can be used underwater to create an area of air so human characters can breathe.
Underwater areas affect gameplay in two major ways: Human characters will drown if they stay under for too long while weapons and equipment will take damage at varying rates until they are destroyed outright.
