Eclipse Phase
A transhuman sci-fi/horror game¸ released under the Creative Commons license (non-commercial¸ share-alike). It is set 10 years after the fall of humanity (""The Fall"") - when the Earth and colonies were devasted by advanced artifical intelligences (TITANs) that went out of control and then disappeared along with millions of humans whose minds were forcibly uploaded. Five wormhole gateways to other systems were found following the Fall¸ and contact has been made with aliens known as the Factors. It uses a percentile skill-based system¸ with success determined by rolling 1d100 under skill + modifiers¸ with doubles (11¸ 22¸ etc.) being critical. Since characters may switch bodies¸ stats are distinguished between ego (self) and morph (current body). Attributes are Initiative¸ Speed¸ Durability¸ Wound Threshold¸ Lucidity¸ Trauma Threshold¸ Moxie¸ and Damage Bonus. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
