The game focuses on the leaders of seven factions, chosen by the player from the 14 possible leaders in "Alpha Centauri" and "Alien Crossfire", and Planet (voiced by Alena Kanka). The characters are developed from the faction leaders' portraits, the spoken monologues accompanying scientific discoveries and the "photographs in the corner of a commlink – home towns, first steps, first loves, family, graduation, spacewalk." The leaders in "Alpha Centauri" comprise: Lady Deirdre Skye, a Scottish activist (voiced by Carolyn Dahl), of "Gaia's Stepdaughters"; Chairman Sheng-Ji Yang, a Chinese Legalist official (voiced by Lu Yu), of the "Human Hive"; Academician Prokhor Zakharov, a Russian academic (voiced by Yuri Nesteroff) of the "University of Planet"; CEO Nwabudike Morgan, a Namibian businessman (voiced by Regi Davis), of "Morgan Industries"; Colonel Corazon Santiago, a Puerto Rican militiawoman (voiced by Wanda Niño), of the "Spartan Federation"; Sister Miriam Godwinson, an American minister and social psychologist (voiced by Gretchen Weigel), of the "Lord's Believers"; and Commissioner Pravin Lal, an Indian surgeon and diplomat (voiced by Hesh Gordon), of the "Peacekeeping Forces".
