Call to Power II is a PC turn-based strategy game released by Activision as a sequel to Civilization: Call to Power, which itself was named after the Civilization series by Sid Meier; this game could not have "Civilization" in its title because the license to the Civilization name was lost.
In October 2003, Activision released the source code, enabling the Apolyton gaming community to debug, improve, and add new features. After being unavailable for a long time, the game was re-released in the digital distribution on GOG.com in 2010.
