Osakar (lanky, parthenogenic quadrupeds) and Mechanons (intelligent robots). Game mechanics The game was a percentile-based system and used only 10-sided dice (d10). Characters had attributes rated from 1-100 (usually in the 25-75 range) which could be rolled against for raw-attribute actions such as lifting items or getting out of the way of falling rocks. There were eight attributes that were paired together (and shared the same rating to begin with)—Strength/Stamina, Dexterity/Reaction Speed, Intuition/Logic, and Personality/Leadership. Characters also each had a Primary Skill Area (PSA—Military, Technological, or Biosocial) which allowed them to buy skills that fell into their PSA at a discount. Skills were rated from 1–6 and usually consisted of a set of subskills that gave a chance for accomplishing a particular action as a base percentage plus a 10% bonus for each skill level the character had in the skill. Weapon skills were based on the character's relevant attribute (Dexterity or Strength) but other skills had a base chance of success independent of the character's attributes. Many of the technological skills were penalized by the complexity of the robot, security system, or computer the character was attempting to manipulate (also rated from 1 to 6). Characters were usually quite durable in combat—it would take several hits from normal weapons to kill an average character. Medical technology was also advanced—characters could recover quickly from wounds with appropriate medical attention and a dead character could be "frozen" and revived later. Vehicle and robot rules were included in the Alpha Dawn basic set. A beneficial feature of the game was its seamless integration of personal, vehicle and aerial combat simulation. The Knight Hawks rules expansion set included detailed rules for starships. The basic set also included a short "bestiary" of creatures native to the world of Volturnus (the setting for the introductory module included with the basic boxed set), along with rules for creating new creatures. Character advancement consisted of spending experience points on improving skills and attributes.
