About
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 leadership.
Geopolitics is your sandbox – unite or break apart nations as best serves your ends, while using those under your influence to conduct proxy wars against the other six factions. Earth’s regions are modeled in detail, from educational levels and unrest to GDP and inequality. Gaining command over regions with great monetary wealth and military power can allow you to implement your will on Earth, but the war for the Solar System will not be won without also securing regions containing space launch facilities.
Enact your will through a council of politicians, scientists, and operatives sent around the world (and even into space). The starting abilities of these councilors will improve through gaining experience and acquiring control over powerful organizations like intelligence agencies or wealthy corporations. A veteran commander may make the perfect choice to lead a tactical team under the council’s direction, while an experienced diplomat works to secure the funding needed to resist the alien invasion.
Seek out like-minded populations and politicians and take actions to convert followers of opposing ideologies. Public opinion is modeled along multiple axes – the Servants’ alien worship and the Protectorate’s advocacy of negotiated surrender may largely align in terms of support or opposition to the aliens, but events that show the aliens can be defeated have the potential to convince followers of the Protectorate that resistance is a realistic choice.

Terra Invicta bridges the gap between our modern-day world and the vast interstellar empires of other space strategy games, asking you to take humanity’s first steps in colonizing our Solar System, where over 300 asteroids, moons, and planets in constant motion create an ever-changing strategic map.
Start your campaign in the modern day and build your capabilities from the ground up, or begin in the near-future and push into the final frontier from the very start – build space stations and planetary bases, quickly gain control of the inner Solar System, and prepare for the existential threat growing at the far reaches of the system.
Take your faction beyond the confines of Earth, building space stations to act as shipyards and fuel depots, constructing mining stations to acquire advanced resources, and establishing bases to serve as research or construction facilities. Terra Invicta zooms into the strategic geography of the Solar System, presenting space not as a series of isolated stars that you order units to move to and from, but rather a rich and varied landscape of asteroids, moons, dwarf planets, gas giants, and other celestial bodies creating texture and tactical opportunities at every turn.
The expansive map is constantly shifting as celestial bodies orbit the Sun. This means your space stations and forward operating bases are constantly moving as well, forcing you to plan accordingly and adapt to the evolving circumstances – your colonies among the Jovian moons could find that a once-distant alien military outpost or Initiative privateering base has suddenly become a close neighbor.

Terra Invicta explores what might be – how colonies on Mars might function, what plausible engines could power our spaceships, and the nature of how space colonization and warfare might proceed. Players may find themselves establishing a mining base on the asteroid 16 Psyche after noticing it is rich in metals – and then learn that in our world NASA planned The Psyche Mission for the same reason.
Exploring and eventually colonizing space will require access to many resources: water for life support and propellant, metals for manufacturing, fissiles for nuclear drives and weapons, and more. At the start, you’ll have no choice but to acquire such resources on Earth and suffer the high cost of using rockets to escape Earth’s gravity, but over time you’ll increasingly choose to instead rely on asteroid mining and other means of securing local supply.
Spaceship design in Terra Invicta draws from the best of scientific speculation and hard science fiction. You can design your own ships, selecting from an array of weapons, drives, and other modules to place on a variety of hulls, ensuring each ship has the right mix of fuel capacity, maneuverability, and other capabilities.
Tactical combat is built around a realistic simulation of Newtonian physics, where momentum and maneuver in 3D space are just as important as the firepower your ships carry. Fire missiles and use point defense cannons to destroy incoming projectiles; build up momentum then swing hard to bring the enemy into your firing arcs; or grapple with the difficult decision to retract radiators and sacrifice heat dissipation to achieve better armor against an incoming enemy barrage.

Terra Invicta is built with modding support in mind, and much of the game is accessible to modders without a coding background. We hope that the Solar System setting and geopolitics simulation will provide a useful framework for modders to realize their own creative visions.

Yeah no this game is pretty much consvoluted and poorly balanced, and just... ♥♥♥♥♥♥♥♥. It's 2045. I have Phased Arrays. UV. Plasma. Battle stations. I slap 4 of these on a ring. I send 9 exo fighters. Nah, I'm dead. by what? 2 alien ships. ♥♥♥♥♥♥♥ 2 alien ships. Yeah. No. Don't buy this game. This game is like a second job and there's no reason to learn about it. I did everything I could, I turtled. I stayed under 100 MC. I focused research. I researched some of the best techs in the game. NOPE! ded. Like what the ♥♥♥♥ was I even building for if TWO MOTHER ♥♥♥♥♥♥♥ SHIPS just NEUTRALIZE 4 ♥♥♥♥♥♥♥ BATTLE STATIONS and 9 ♥♥♥♥♥♥♥ EXOFIGHTERS ♥♥♥♥♥♥♥ HELL?
By all rights I should love this game & I have tried - oh how I have TRIED. It is garbage, in more ways than I can even touch upon to explain in my rage addled mind.

Great Strategic Alien Invasion - World Defense - Factions - Espionage - Wars - Space Ships - Invasions - Alien Infiltration and more. Reminiscent of old school X-Com UFO Defense's Strategic gameplay (while modernized).l
This game is unplayable. It crashes when the computer takes a turn. It crashes when I try to save. It crashes when I load a save. I cannot get past a month or two of gametime. Updated drivers, lowered graphics specs even though my computer can handle so much more but it makes no difference. This game is trash.
Terra Invicta is easily one of the best grand strategy games I've played in a long, long time. It's hard to learn, don't get me wrong. I have something like 260 hours and I still don't know everything about this game, but that doesn't matter. Every faction takes you down a different path, the space combat is insanely detailed if you have the balls to learn it. If you don't like slow games, maybe go somewhere else, but being able to influence world events years prior is such a great feeling. This isn't a game you'll see yourself play everyday for several months, but you will definitely have some month long campaigns (unless I'm doing something wrong and it's supposed to be shorter)
'I don’t have the time for this, 250 hours later and right when I’m at the finish line, I realize I just don’t care anymore and stopped having fun a long time ago, not to mention the performance issues this late in the game.' Probably the most relatable part of a review ahead of mine. I think there are a heap of super complex games like Civ but where this one goes wrong is it forgets to make the learning part fun. I could completely see myself spending hours to learn this game, only to realise even know how it works, it's not fun.
Theres really nothing like this. Long form, structurally disadvantaged grand strategy over time and space. Factions and quotes clearly take inspiration from Alpha Centauri, another titan of the genre. Space combat is realistic mostly, the controls are imo tough to get behind however, Most space combat is about the >"Dont Be There" portion of the Survivability onion. When you do coalesce for your first space battles you time it right and suddenly mass and overpower an alien fleet and then go back into hiding. Building an alien killing-capable fleet however needs a LOT of planning in the long term, as you need to extract as many resources as you possibly can as quietly and quickly as you can, before the Aliens become too strong. On the planet, your operatives need to take control of countries and merge them into power blocks like the EU or North America, to lessen the control burden and allow you to take more control. The ground game is critical in the "early" game(~10-30 years), and the game does a good job of giving you simple automation tools so that when you focus mostly on space you dont pay much attention on earth when it doesnt matter. Speaking of which, Nuclear conflict is a thing as is climate change. Throw up enough debris from nuclear war and you can curtail climate change for a while, at a massive GDP cost to every country. If you're the Servants looking to pave the way for aliens, starting nuclear war is always priority 1 as it disables most factions early and allows the Aliens a quicker and easier time on the planet Overall, extremely fun, with these different systems integrated really well.
This game can consume all my freetime and mind space for a month or more. I really like controlling countries, guiding their development, seeing the world change, finding cool orgs, building mines and space stations, and most importantly: constantly learning new intricate things about the game and its many systems. I'm not very good at figuring out things with space combat, but even playing with mostly early game systems is worth the price of admission to me. I definitely recommend you watch through Perun Gaming's playthroughs to learn ways to think about the game and its systems. Watching those entertaining videos was really what hooked me on this game.
希望能给玩家减负
Fascinatingly complex and deep - it is not a game for a casual players. Seemingly endless research tree with both player-specific and communal research, realistic and deeply explained technologies with multiples pros and cons, a very complicated ship design and upgrade logic, ship combat, real solar system physics affecting all your movements and even resource production, it is really superior. Add to this politics, land warfare, champions (eg councillors)... It is intentionally very slow - which might be a good and a bad thing. My two complaints are: - The alien faction is stupidly overpowered, even at the lowest difficulty - it could be very frustrating and feeling unfair - I mean, you are ahead of all other factions and it takes 180 game days to build a single ship, yet aliens could throw at you 40-ship strong fleets every other day with a single gunship more powerful than your midgame dreadnought. - There is too much micromanagement, which should be streamlined - eg abilities to queue orders to you councillors, fleets, etc
