Characters in Xerospace have six Traits (Attributes), namely: Dexterity, Movement, Size, Perception, Tech, and Psionic. Characters select two traits in which they are "better than most" and two traits in which they are "not as good as most". Traits are then assigned values of 5, 6, or 7, depending on their categorization. Each trait in turn yields up to three starting Skills and each character may select a total of five starting Skills. Characters will start with Skill Values of 5-10. Characters also have a variety of other traits including Mutations, Life and Energy. Mutations are special abilities (beneficial) and work much like bonus Skills.
Skill resolution is performed by 2d6 plus related Skill Value plus related Trait Value, producing a number from 1-21. Various types of success (or failure) are supported based on the results--each Skill uses a unique chart of results. Whenever a character rolls "Doubles" on a Skill check this is noted and eventually leads to a Skill Value increase.
Combat is atypical inasmuch as each "turn" is divided into three "rounds" which are, in order, Preparation Round, Maneuver Round, and Resolution Round. Combat otherwise resolves much like a Skill resolution. Note that "Combat between spacecraft should be run just like combat between individuals".
