GURPS 4th edition. Transhuman Space: Deep Beyond

The Edge of Nowhere

The Deep Beyond is the solar system's final frontier. A vast zone stretching from the asteroid belt to the edge of interstellar space, its siren call has drawn researchers, pioneers, visionaries – and outlaws. Deep Beyond includes:

Expanded descriptions of the asteroids, gas giants, moons, and comets of the outer system. Visit the gas mines of Saturn and Europa's icy oceans!
What it's like to grow up in the Deep Beyond . . . as a Duncanite parahuman, a sapient AI, or even an enslaved bioroid.
Dozens of organizations, from the rebel ghosts of Axon to the cyber-soldiers of the 82nd Spaceborne.
New character types, from judges-for-hire to Jump RATS and Swarmdozers.
New vehicles and technologies: ice-hulled Gypsy Angel spacecraft, portable lasers, prospector swarms – even the black hole power plant.
