Netspace
This 30-page resource expands futuristic d20 roleplaying with rules for virtual reality and the characters who use it. Players can create self-evolving artificial intelligences, Net-adapted humans, and neurohackers who manipulate virtual environments through specialized paradigms. The guide details Netspace domains and zones, virtual movement and combat, access technologies, cybernetics, and defenses such as icewalls. Neurohacking skills allow characters to alter virtual reality, attack minds, create objects, and emulate abilities, while new feats provide additional options. Templates and guidance are also included for virtual creatures and powerful AI characters.
