The Most Scientifically Accurate Space Warfare Simulator Ever Made.

Children of a Dead Earth is a simulation of true-to-life space warfare. Design your spacecrafts using real world technologies. Traverse the solar system using actual orbit mechanics. Command fleets as the solar system descends into war, and see if you have what it takes to become the victor.

  • REAL SCIENCE, REAL TECHNOLOGY - Every technology, from the Nuclear Thermal Rockets, to the Railguns, to the Magnetoplasmadynamic Thrusters, was implemented using actual equations from Engineering and Physics textbooks and white papers. Every aspect of these systems, efficiency, size, mass, power usage, heat dissipation, are all derived from valid equations.

  • CAMPAIGN AND SANDBOX MODES - Assume the role of an admiral and fight through a detailed storyline chronicling the descent of the solar system into all out war, spanning every planet in the solar system and everything in between. Or simply play in the sandbox, designing ships and pitting them against other ships.

  • EXTREMELY ACCURATE ORBITAL MECHANICS - With an N-Body Simulator (the kind NASA uses to plot spacecraft trajectories), all orbital phenomenon from hyperbolic orbits, Lagrange points, and orbital perturbation are all correctly simulated. Spacecrafts can stationkeep orbits, or enter into free falling perturbed orbits.

  • 1:1 SCALE - The solar system is modeled completely to scale. The sizes of all planets, moons, and asteroids are accurately enormous, and the distance between them is similarly huge. The extremely high orbital speed of your ships deep in high gravity orbits is correspondingly correct.

  • FREEFORM SHIP DESIGN - Build your spacecrafts out of rockets, propellant tanks, weapons, powerplants, radiators, and crew modules. Wrap it all up with multiple armor layers, and maybe a Whipple Shield to boot. The acceleration, moment of inertia, delta-v, and much more are all correctly calculated for all spacecrafts you design.

  • HIGHLY GRANULAR MODULE DESIGN - Tweak everything from the nozzle length or stoichiometric mixture ratio of your bipropellant rockets to the armature and rail dimensions of your railguns. The results of every change is seen in real time, from the change in your rocket's exhaust velocity, to your railgun's inductance or muzzle velocity.

  • PHYSICALLY ACCURATE MATERIAL PROPERTIES - All materials, chemical reactions, and spectra are physically correct. When your arclamp pumps your solid state laser, the pumping bands need to match up with the actual emission spectra of your excitation gas. When the photon absorption of a material is needed, it is derived from actual refractive index spectra data.

  • IN-ENGINE MOD SUPPORT - The engine supports black box creation of untested or far future technology for modders to work with. All other game data, from levels to material properties, is also accessible to modders.

  • STEAM WORKSHOP SUPPORT - Subscribe to mods on Steam Workshop, and they will automatically load. In-game export tools allow instant uploading of your own designs to Steam Workshop.

All of the above aspects combine to yield a space warfare simulator that is unparalleled in scientific realism. No other game combines the extremely accurate orbital mechanics, 1:1 scale of the solar system, and technology which is implemented 100% by scientific equations. If you ever wanted to know what space warfare would actually be like, this is the game for you.

Children of a Dead Earth reviews and comments

A strategy game in the space but with a twist! The gameplay takes into account Newtonian physics and the player will have to expose him if he wants to win the many missions offered in this game. The presentation is very nice with minimalist but efficient graphics and a soundtrack that puts in the atmosphere of a large scale space. The gameplay could be more than one because the difficulty curve is some can be raised (having played other space simulators will help to understand some astronavigaton conscepts) but over the course of the tutorials and time the game offers a gaming experience unique and satisfactory. In addition the game offers a sandbox mode that allows to create its own missions, ships and weapons. A recommended game for strategy fades in search of originality and other space junkies.

Only Recommended if you are really a Fan of these Types of Games! If you want the most important Knowledge, last Paragraph. Personally, I think it's a good Game concept. Someone already said it in an English Review, it's like Kerbal Space Program if you had decided to build it up as a Military Game. But that is precisely the Point. It plays out like an Early Access from the content available. I tend to say that the value for performance here is not consistent. Pro:-Good Simulation Interface with good Tutorials about the Campaign-Stimmiges Concept with space fights as you know it from science fiction works by authors, for example, which more address the scientific Aspect. -Cleanable User Interface-Diverse tactical Possibilities from direct Attack via drone and Rocket use. -The possibility to put together your own Spaceships via the Designer Contra:-No Multiplayer-Just a Campaign that you can create in 5 Hours and is not really gripping from the Story-A Sandbox simulator that contains only pure Space storage Temples-A Fast Flattening Gaming experience-Hardly Replay value-No attacks on planets themselves, only on Space-based installations-Only a One-sided Campaign representing only one of Two possible Factions-The Designer has unfortunately not succeeded very well. Most features you can find out with something clicked, but the Designer's UI is rather bad. Conclusion I would say more of a strong 2 to a weak 3 out of 5. The Game can make You feel like if you feel like it Or if you can also Motivate yourself. And that is precisely the Point. You shouldn't Have to Motivate yourself for a good Game. If there were more Content or a proper Career Mode or at least a MULTIPLAYER would make the Game really Whim. I think that is also the most important Point. This Game would be great for a Multiplayer. That would enhance the whole Gaming Experience. In the current State, all I can say is that if you are a Fan of realistic Space space Hubs, just as they would be Scientific at the moment (FlyBy Maneuvers, Broadside Weapons, Rockets and Drone Use), it's just right. Otherwise, I advise caution at the Price, it might Disappoint you otherwise!
