Earth 2140 is a 2-D real-time strategy computer game created in 1997 by Polish-based Reality Pump Studios and published by TopWare Interactive (later acquired by Zuxxez Entertainment). Due to lack of publicity and marketing, the game was virtually unknown in the United States as well as Western Europe. It has two sequels, Earth 2150 and Earth 2160.
Although not popular in US and Western Europe, the game sold quite well in Turkey, as it was one of the few foreign games ever released with a Turkish language option.
