Eclipse Phase is a post-apocalyptic game of conspiracy and horror. [11] It takes place after a World War III project to create artificial intelligence has gone rogue under the influence of an extraterrestrial entity known as the “Exsurgent” (best described as an organic computer virus with the capacity to infect both machines and animals Sapient qualities), resulting in the deaths of 90% of the inhabitants of Earth.

Earth is subsequently abandoned, and existing colonies throughout the Solar System are expanded to accommodate the refugees. The setting of a spectrum of socioeconomic systems in each of these colonies:

  • A capitalist / republican system continues in the Inner System (Mars, the Moon, and Mercury), under the Planetary Consortium, a corporate body which allows nominally most powerful shareholders.
  • An Extropian / Propertarian system is established in the Asteroid Belt . The Extropians are split into two subfairs, an anarcho-capitalist group, more closely related to the Hypercapitalists and a mutualist group, related closely to the Anarchists.
  • A military oligarchy rules the moons around Jupiter.
  • An alliance of Scandinavia-style social democracy and collectivist anarchism are dominant in the Outer System.

From there, the setting explores various scientific advances, extrapolated far into the future. Nanotechnology , terraforming , Zero-G living , upgrading animal sapience , and reputation systems are all used as plot points and background.

With all of this, the game encourages players to confront existential threats like aliens, weapons of mass destruction, Exsurgent Virus outbreaks, and political unrest.


Eclipse Phase uses a simple roll-under percentile die system for task resolution. [12] Players roll the percentile dice (by rolling two ten-sided dice with one of the dice representing a 10 value), and compare that roll to a target number with the goal being to match or go under that number with the roll. Unlike most similar systems, a roll of 00 does not count as a 100. In addition, any roll of a double (11, 22, 33 etc.) is a critical. If the double is under the target number it is a critical success. For damage resolution (whether physical damage caused by injury or mental stress caused by traumatic events), Players roll a designated number of ten-sided dice and add the values ​​together, along with any modifiers. [13]
