Using the GURPS 3rd Edition rule set, Transhuman space is a science-fiction role-playing game that explores biology, genetics, nanotechnology, artificial intelligence and future sciences to create a vibrant "possible future" setting. Transhuman Space is a "hard" sci-fi game that strives to maintain the plausible over the impossible. Completely set within the solar system, with no faster-than-light travel or alien races - yet, all the more compelling for the avoidance of those standard sci-fi tropes.
