Nexus: The Jupiter Incident is a science fiction themed real-time tactics computer game developed by the Hungarian-based Mithis Entertainment. The game focuses on tactics and ship management instead of resource collection and base construction. In each of the game's missions, the player is given a small number of large space ships (always less than ten, and sometimes just one or two), along with accompanying fighters and bombers. The ships are large and cumbersome, and the battles between fleets protracted, giving the game a noted cinematic feel. Nexus uses the Blacksun Engine, made specifically for the game. Based on DirectX 9, it makes extensive use of vertex and pixel shaders, a parametric particle system, and other visual effects. The game is set in the 22nd Century. The player is Marcus Cromwell, a famed spacecraft captain whose father, Richard Cromwell, the first spaceborn human, captained the colony ship Noah's Ark through a wormhole near Mars that was presumed destroyed when the wormhole collapsed. Cromwell sets out on the SpaceTech heavy corvette, the Stiletto, for Jupiter. The events that unfold are "The Jupiter Incident", which escalates into an interstellar war. Cromwell engages in battle with several ships and responds to a Kissaki Syndicate (a rival corporation) research base's SOS call. Inside, he finds a cruiser-sized ship of alien origin, named the Angelwing by the Kissaki. The ship's logs show the corporation has another hidden base close to Pluto, with the base that sent out the SOS call being a distraction for the top-secret research being carried out at the Pluto base. A normal ship would require almost 4 years to make the trip; however, the Angelwing can make the trip in several weeks using its special IP Drive. After a battle with the Syndicate fleet for the control of the Angelwing, Cromwell is given command of the cruiser and ordered to investigate the secret base. At Pluto, an artificial intelligence, named Angel, uploads herself into the Angelwing and commands Cromwell to escape from a strange entity - later known as a Mechanoid - through a nearby wormhole, the same wormhole that collapsed near Mars. Cromwell finds himself in the Noah system populated by the colonists from Noah's Ark, who survived the wormhole collapse and started a colony. The Noah Colony fights as a mercenary race for an advanced but peaceful alien race, called the Vardrags, against another powerful race, the bloodthirsty, reptilian Gorgs, and a local group of renegade Vardrag elites, known as the Raptors. After a successful raid at the Raptor's base, they are then enlisted again to fight against the Gorg Empire. In fights against the Gorg, the Ghosts occasionally seem to help the Angelwing. However, all the races would soon find themselves facing their greatest threat: a virulent race of nanomachines called the Mechanoids. Nothing seems capable of stopping the Mechanoid invasion, and the Vardrag homeworld and Earth are overrun. Only an organic, insectile race, known as the energy-consuming Locusts, are immune to the Mechanoids. With technology adapted from the Locusts, Cromwell is able to rescue Earth and all the other solar systems and shut down the main control system of the Mechanoids, the Entity. The fate of Angel, who fought the Mechanoids, is left ambiguous, as she was not shown leaving the Entity and returning to the Angelwing.
