Firaxis Games, Inc. is an American video game developer based in Sparks, Maryland. The company was founded in May 1996 by Sid Meier, Jeff Briggs and Brian Reynolds following their departure from MicroProse, Meier's earlier venture. They were acquired by Take-Two Interactive in August 2005, and subsequently became part of the publisher's 2K label. Firaxis Games is best known for developing the Civilization and XCOM series, as well as many other games bearing Meier's name.

Sid Meier's Alpha Centauri is a 4X video game, considered a spiritual sequel to the Civilization series. Set in a science fiction depiction of the 22nd century, the game begins as seven competing ideological factions land on the planet Chiron ("Planet") in the Alpha Centauri star system. As the game progresses, Planet's growing sentience becomes a formidable obstacle to the human colonists.
