Germ Warfare takes on a new meaning. Biological warfare is missing from many sci-fi games. I thought it was a nice touch. It could have germs. Gengineered plants are also covered in depth.
Insects are no longer a nuisance they're fatal.
Engineered and modified animals are also covered. The chapter ends with Living Bioships. Anybody watching Farscape may get an idea of what this is about. This chapter covers Cryonics, Suspended Animation, and Braintaping. This offers a very cool element to any sci-fi game.
