Eclipse Phase

Eclipse Phase is a transhuman science fiction horror role-playing game set in a post-apocalyptic solar system. Humanity, having narrowly survived an AI uprising, struggles to rebuild and faces existential threats from within and beyond.

Theme and Setting

The game explores themes of transhumanism, consciousness, and the nature of identity in a world where minds can be transferred between bodies and exist as pure data. With its skill-based mechanics, tactical combat, and narrative-driven gameplay, Eclipse Phase offers a unique and challenging experience for players interested in cyberpunk, dystopian settings, and dark themes.

How Play Feels

Eclipse Phase plunges players into a dark, post-apocalyptic future where Earth has been ravaged by rogue artificial intelligences known as the TITANs. The survivors have fled to colonies scattered across the solar system, each with its own distinct socioeconomic system, ranging from capitalist republics on Mars and the Moon to anarcho-capitalist Extropians in the Asteroid Belt and Scandinavia-style social democracies in the Outer System.

What Makes It Distinct

The game explores transhumanist themes, such as mind uploading, body modification, and the implications of advanced technology on human identity. Existential threats abound, from remnants of the TITANs to alien encounters and the ever-present danger of the Exsurgent virus.
