Earth 2140 is a 2D real-time strategy computer game created in 1997 by Polish-based Reality Pump Studios and published by TopWare Interactive (later acquired by Zuxxez Entertainment).

Tensions rise between the Earth's two major factions, the Eurasian Dynasty (ED) and the United Civilized States (UCS), as both sides vie for the world's steadily dwindling resources.

A glitch in the upgrade of the UCS war processor GOLAN caused the giant robot to miscalculate the military strength of the Eurasian Dynasty, thus compelling it to launch an attack on the ED.

The UCS is generally more technologically advanced than its adversary, employing robot infantry and automated bipedal combat vehicles (more commonly known as mechas).

The antithesis of the UCS, the ED is run by an autocratic monarchy under the Khan Dynasty that often makes life harsh, short, and without luxury for its citizens.

As the less technologically advanced of the two factions, the ED utilizes cyborgs, traditional 20th century standard vehicles such as tanks, and armed helicopters in its arsenal.

Capturing the opposing faction's factories enables the player to make use of otherwise unavailable technology (depending on the research center progress).

Most of the units and vehicles just move, attack and escort, but certain ones serve with special tasks such as mine laying, cargo carrying and others.
