Set somewhere after 2208, the back story of Perpetuum explains that humanity, in search of alternative energy sources, has stumbled upon technology to create tiny particle-sized wormholes, creating shortcuts through spacetime. After sending miniature probes out to map known extrasolar planets, one of them stumbled upon a planet designated Nia, home to a synthetic, robot-like lifeform. It was soon discovered these lifeforms have unique and efficient ways to produce energy, so it was to become an objective for conquest. Earth-based IT specialists found a way by using probes to hack into the alien information system, enabling them to take over several lifeforms and set up a base, facilitated by the fact that most of the alien lifeforms were already divided by a long-standing war and were unable to respond quickly to the takeover. Now that the conquest has begun, the aliens have reinforced their networks and the war will have to be decided on the ground. As it stands, human pilots known as agents control their robots remotely, participating in the Perpetuum Project, with their main goal to transfer as much energy as possible back to earth.
