Earth 2150 Trilogy is the second game in a largely unknown series by Polish developer Reality Pump Studios. This trilogy includes two stand-alone expansion packs that enhance the story of the original Earth 2150. The unique aspect of Earth 2150 Trilogy is that it allows the player to research and build his/her own vehicles for use in the game. Earth 2150 Trilogy also contains a wide-range of warfare, with campaigns taking place on the sea, land and the air. Somewhat unusually for games of this type, there is a detailed story mode as well.
