Perpetuum is a video game by Avatar Creations Ltd. It is a player-driven persistent-world MMORPG set in a science fiction ground setting. Players pilot customisable robots on various islands connected by several teleports. These islands are either alpha ('safe' from attacks by players) or beta/gamma, meaning players can freely engage each other. Players of Perpetuum are able to participate in a number of in-game professions and activities, including mining, logistics, missions, manufacturing, trading, artifact hunting and combat (both player versus environment and player versus player). The range of activities available to the player is facilitated by a character advancement system based upon extension points accumulation (EP) in real time, even while not logged into the game. Perpetuum was first released worldwide via a digital distribution scheme on 25 Nov 2010, following a period of closed and open beta testing. The first major upgrade was the version of Perpetuum dubbed Terra Incognita, which was released on 4 May 2011. The second (current) major upgrade was released 1 June 2012, and is dubbed Gamma Frontier. The main feature of the upgrade is 24 new terraformable islands where player-built settlements (networkable buildings and defensive structures) can be constructed. In April 2014, Perpetuum has dropped its subscription payment model for a pay to play payment model., and released on Steam, being previously greenlit. The game closed its servers on 25 January 2018, with the server code being open sourced and handed over to the community. Setting 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
