Alternity emphasizes storytelling over statistics, and players are encouraged to use their role-playing skills and imaginations. But your polyhedron dice will still get a workout; Alternity employs a clever method of success determination that uses both a 20-sided die and second "situation" die that varies depending on the difficulty of the situation. The Player's Handbook (along with the Alternity Gamemaster Guide) contains all the rules necessary to play, including a "Quick Rules" section that allows players to jump in quickly. Additional sections cover character creation (featuring five alien races and several professions to choose from), mutations, psionics, weapons and equipment.
