Eclipse Phase is a post-apocalyptic game of conspiracy and horror. [11] It takes up after-a World War III project to create artificial intelligence has gone rogue under the impact of an extraterrestrial entity Known as the “Exsurgent” (best Described as an organic computer virus with the capacity to infect Both machinery and animals with sapient qualities), resulting in the deaths of over 90% of the inhabitants of Earth.

Earth is now abandoned, and existing colonies throughout the Solar System are being expanded to accommodate refugees. The setting explores 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 permits the election of representatives and whose shareholders are nominally most powerful.
  • An Extropian / Propertarian system is established in the Asteroid Belt . The Extropians are split into two subfactions, 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 , animal upgrading sapience , and reputation systems are all used as plot points and background.

Aliens, weapons of mass destruction, Exsurgent Viruses, 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 compares that roll to a target number with the goal being matched to the number with the roll. In addition, any roll of a double (11, 22, 33 etc.) is a critical. If it is a critical success, it is a critical success. Physical damage caused by injury or mental stress caused by traumaticevents), players rolled a number of ten-sided dice and add the values ​​together, along with any modifiers. [13]
