About Terra Invicta
✦ AI summary
Lead one of seven ideologically-driven factions competing for control of Earth's regions and resources as an alien invasion approaches, using politicians, scientists, and operatives to wage shadow wars and steer global policy toward your vision. Expand into the dynamically-orbiting Solar System to establish space stations, mining operations, and research bases while uncovering the truth behind the extraterrestrial threat and racing to secure humanity's future among the stars.
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.
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.
- 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.
- 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.
- 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.
- 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.

OMG, this is my 3rd time trying to play the game. This time, I did it different. I have Gemini AI helping me make decisions. When ever I don't understand something, I ask Gemini and it gives me a deep understanding. After using this strategy, I have to say this game is absolutely in my top tier of games ever made. If I do another play through, I won't need the AI for over 90% of my decisions. But the gemini AI is like a superhigh level tutuorial/game guide. If you try this strategy, leave me a comment and tell me if you think it helped you.
Early game is basically a turn-based whack-a-mole and nation hopping.
Strategy game fentanyl
This is my perfect game and I cannot in good conscience recommend it to anyone. It's filled to the brim with weird decisions: A million different techs that are more or less equivalent to one another, a tutorial that explains what the buttons do but not why you should press any of them, a nation management system more or less designed to make you cook whatever nations you control, and a good half dozen other player traps that will cook your run. You spend a good 50% of every game convinced you've cooked it and it might be easier to restart than persevere in your doomed world. AND YET it completely consumes me every time! The way a strategy you conceived of literally dozens of hours ago slowly takes shape and then pays off, that feeling of crushing the aliens after getting your head bashed for hours, slowly strangling the life out of the aliens and other factions, it's all just incredible. If you value your time, and are unwilling to put up with what can only be described as hostile design, then don't play this, of course. But if you enjoy grand strategy with a truly competent adversary/s, a massive scope, and a true sense of accomplishment at the end of a grueling fight, then thi…
This has to be one of my all time favorite Sci Fi games I have played. It's from the devs of the famous Long War mods for the Xcom games and comes with all the depth and and effort you could hope for based on this. The game is huge and easy to get lost in but there's not overly much hurry for quite a while and you've got some time to figure things out or even to catch back up from a slow start before you need to start defending Earths orbit or are even seriously capable of it. Most of the learning is just figuring out what things mean relative to others. such as finding out that having lots of fuel (delta V) means nothing if your ship is so slow it can not escape earths gravity because you have only 1 engine trying to push several thousand tons of fuel like the worlds largest bomb. And who cares if you have no idea what makes a functional space navy? Experiment and find out for yourself with tons of near future and theoretical options for technologies from trying to adapt the engines used for satellites to make a fuel efficient but slow exploration ship able to set up new outposts in the far reaches of the solar system to investing in nuclear powered engines tested by NASA decad…
Great game - verymuch has "Cold War Paradox" vibes in terms of being a grand strategy where a major portion of the gameplay is not knowing exactly what your opponents are up to. Definitely the most complicated grand strategy I've played. Has the worst tech UI I have ever seen - you WILL be incredibly confused. Still at 100 hours and haven't gotten into ship combat because I've spent all this time just learning first how stuff on Earth works, then how stuff in space works. Desperately needs a tech-UI-overhaul.
