Terra Invicta(V0.3.108)

【Game Introduction】

an alien probe was found approaching the earth. What humans don't know is that an alien force has reached the frosty outer edge of the Kuiper Belt belt and has begun to mine minerals on a dwarf planet in preparation for invasion.
governments have been slow to agree on how to deal with aliens who are about to visit Earth. As a result, like-minded political, military and scientific leaders from different countries have developed secret coordination channels on their own. Because the motives of aliens are unknown, many camps have emerged driven by hope, fear or greed.
you will control one of the camps. The resistance tries to build an alliance of nations to work together to defend
the human faction vows to kill all aliens and any human
submissive faction that cooperates with aliens, worshiping the aliens, believing that they can solve all the world's problems
the Anglophiles propose to negotiate surrender. See this as the only way to avoid human extinction
academics hope that the arrival of aliens will bring the earth an opportunity to form an interstellar alliance.
the initiative attempts to profit from chaos and destruction.
the runaway faction plans to build a huge starship, flee an anomaly in the


of the solar system, a mysterious crash site, and sudden reports of a large number of missing persons. Is this really the first contact between humans and extraterrestrial life? When field personnel investigate sightings and scientists try their best to explore new areas of research, you will gradually understand the truth behind the arrival of aliens. From early sightings and UFO crash sites to raging alien behemoths and droid armies, you will soon understand that the other six human camps are not your only competitors. In the course of the game, when you investigate the increasing alien activity on Earth, the events shown in illustrations will make you face difficult choices. You have to explore the origins and motivations of aliens-unless, of course, you are human, because the only thing that matters to them is the extermination of aliens.
Unyielding Earth has a global scientific research system that creates opportunities for competition and cooperation. Shared scientific progress will unlock private engineering projects. Camps can choose to focus on private projects at the cost of weakening the planet as a whole and ceding influence on global research to other camps with other priorities. If unregulated, camps such as obedience or initiative may manipulate the direction of global scientific research, giving priority to the development of methods of social control over power systems or weapons systems.


you are the leader of a secret organization on earth that works for the ideology of your choice. Aliens are coming, but your first enemy (or ally) will be another human camp. Lead a camp United by ideology, not a country defined by territory. This is a big difference from most strategy games-in unyielding Earth, you don't control the country you choose to fight north and south. You will rule in the shadows, competing with other camps for control points (which represent the military, economic, or political leadership of a region).
geopolitics is your sandboxie-do what is best for your goals, unite or divide countries, and use the countries you influence to wage proxy wars against six other camps. All parts of the planet are modeled in detail, from education and riots to GDP and inequality. Controlling areas with great wealth and military power can exert your will on Earth, but it is impossible to win the war for the solar system without occupying areas with space launch facilities.
fulfill your will through a council of politicians, scientists, and special agents dispatched around the world (and even to space). The initial capabilities of these directors can be enhanced by gaining experience and gaining control of powerful organizations, such as intelligence agencies or high-profit enterprises. Experienced commanders can make the perfect choice to lead tactical teams under the direction of the Council, while experienced diplomats will try to stabilize the sources of funding needed to resist alien aggression.
look for like-minded people and politicians and take action to transform followers of hostile ideologies. Public opinion is shaped on multiple axes-the alien worship of obedience and the negotiated surrender advocated by the security faction may be pro-alien ideologies, but if there are events that show that aliens can be defeated, it is also possible to convince pro-security supporters that resistance is a practical option.


most space strategy games presuppose a grand interstellar empire or alliance background. However, few people explore the current state between the Earth and the interstellar empire or alliance, and the "unyielding Earth" fills this gap. In unyielding Earth, you will realize the first steps for mankind to go into space on a large scale. There are more than 300 small moons, moons and planets in the solar system, which are constantly moving to create ever-changing strategic maps. You need to lead your camp to break through the restrictions of the earth, build space stations as docks and fuel stations, set up mines to obtain advanced resources, and set up bases for research or construction facilities. Unyielding Earth magnifies the strategic geography of the solar system. Instead of presenting space as a series of independent planets in which you order your troops to move, it is a rich and diverse terrain made up of small moons, satellites, dwarf planets, gaseous giant planets and other celestial bodies, each turning point can create new situations and tactical opportunities.
as the celestial bodies move, the vast maps are constantly changing. This means that your space station and forward base are also moving, forcing you to plan according to the situation and adjust to the evolving environment-colonies among Jupiter's moons may find that an alien military base or active privateering base in the distance has suddenly become a close neighbor.


Indomitable Earth explores the possibilities of the future, including how the colonies on Mars operate, which seemingly reasonable engines can power the spacecraft, and how to conduct space colonization and war. Players may discover the rich metal deposits on the small moon 16 Psyche and set up a mining base on it-and then discover that in our world, NASA is planning the Ling Star mission for the same reason. From exploration to space colonization, many resources are needed: water for life support and propellants, metals for manufacturing, fissionable materials for nuclear power plants and weapons, and so on. In the beginning, you have no choice but to get these resources on Earth and endure the high cost of using rockets to get rid of Earth's gravity. But over time, you will rely more and more on small satellite mining and other ways to secure local supplies.
the spaceship design in Unyielding the Earth draws on the best scientific reasoning and hard-line science fiction. You can design your own ship, choose from a range of weapons, engines and other cabins, and place it on a variety of ships to ensure that each ship has the right combination of fuel capacity, maneuverability, and other functions.
tactical combat is built around real simulations of Newtonian physics, so the movement and movement in 3D space is as important as the firepower carried by the ship. Launch missiles and use fixed-point defense cannons to destroy incoming shells; accumulate momentum and then attack vigorously to pull the enemy into your firing arc; or make difficult decisions to withdraw the radiator and sacrifice heat removal efficiency in order to gain better defense shields. against incoming enemy firepower.

"Unyielding the Earth" is designed with support modules in mind, and many parts of the game are freely accessible to module designers who do not have a programming background. We hope that the design and geopolitical simulation of the solar system will provide a useful framework for module designers to realize their own creative vision.
the non-English translation of unyielding Earth is still being tested and improved. The game has a text equivalent to the content of several novels, and we know that there will be some problems-please be patient, we are correcting the problems and improving the quality of translation.
