An extraterrestrial probe is detected approaching Earth. Unknown to humanity, an alien force has arrived in the far reaches of the icy Kuiper Belt and has begun mining a dwarf planet to prepare for an invasion. With Earth’s nations unable to unite to address the alien arrival, transnational groups of like-minded political, military, and scientific leaders develop covert channels to coordinate a response. With the aliens' motives uncertain, factions emerge, driven by hope, fear, or greed. You will control one of these factions. The Resistance works to form an alliance of nations to mount a coordinated defense Humanity First vows to exterminate the aliens alongside any who sympathize with them The Servants worship the aliens and believe they will solve all the troubles of the world The Protectorate advocates negotiated surrender as the only means to avoid annihilation The Academy hopes the alien arrival heralds the opportunity to form an interstellar alliance The Initiative seeks to profit from the chaos and destruction Project Exodus plans to build a massive starship and flee the Solar System A distant anomaly, a mysterious crash site, and a spike in reported disappearances. Could this truly be humanity's first contact with extraterrestrial lifeforms? As your field agents investigate sightings and your scientists race to explore new fields of research, you will slowly learn the truth behind the alien arrival. From early sightings and UFO crash sites to rampaging alien megafauna and robotic armies, it will rapidly become clear that the other six human factions are not your sole competition. Throughout the game, illustrated events will present you with difficult choices as you investigate growing alien activity on Earth. Uncover the mystery of the aliens’ origins and motives – unless, of course, you are Humanity First, and all that matters to you is extermination. Terra Invicta has a global research system that creates opportunities for both competition and cooperation. Shared scientific advancement unlocks private engineering projects. Factions can choose to focus on private projects, at the cost of weakening Earth as a whole and ceding influence over global research direction to other factions with different priorities. Left unchecked, factions like the Servants or the Initiative may steer the world’s efforts toward developing methods of social control, rather than propulsion or weapon systems. You begin on Earth as the head of a shadowy organization devoted to your chosen ideology. The aliens are coming – soon – but your first enemies (and perhaps allies) will be other human factions. Lead a faction united by ideology, rather than a nation defined by territory. This is a stark change from most strategy games – in Terra Invicta, you will not paint the map with the colors of some chosen nation. Instead you will rule from the shadows and compete with other factions for control points representing a region's military, economic, and political leaders
