Full Changelist
1.2.0 (12/18/2017)
- Foreign Language Support
--- Non-English languages are now supported, and fan-made translations can be imported. A fan-made Chinese translation is in the works.
--- A language file with all strings can be imported, as can language specific images (such as the main logo), and font files.
- Ship Design
--- Form fitting, concave armor is allowed on ships. Concave armor has a smaller cross section and can sometimes save mass, but also can suffer from multiple bullet ricochets.
--- Polygonal cross section armor for ships allowed, such as triangular, hexagonal, and so on.
--- Spinal modules can be pushed inwards or outwards, allowing setups such as propellant tanks around crew modules.
--- Front and back facing attached modules also can be pushed inwards or outwards, allowing setups such as frontal guns stacked with different frontal guns.
--- Ship armor can be radially rotated about the ship (you can now edit the start and end percent for each radial span).
--- Radiation shielding is more properly calculated.
--- Weapon firing arcs can be limited by ship armor now. Ship design warns of these cases.
- Module Design
--- Added Fuse modules, which are tiny modules which can trigger Ordnances or Engines after a set amount of time. Allows for time-delayed flares or timed explosives, or for launching dumbfire missiles (with optional timers).
--- Reduced Remote Control size.
- UI
--- Materials, modules, and spacecrafts are all listed in a grid view when choosing them. The grid organizes items by mass, cost, and every other property, each of which can be toggled or sorted.
--- Ship and Module Design menus can be toggled to a grid view rather than the default list view.
--- Can enter degrees into radians sliders.
- Graphics Updates
--- Spacecrafts cast shadows on themselves and each other in combat and design.
--- Many stock spacecrafts are updated to have form fitting armor and sloped nose cones. Some have polygonal cross sections now.
--- Radiators are animated in module design. Engines bells and gun barrels too.
- Mods
--- Exposed ship armor limits in Limits.txt.
- Other
--- Renamed weapon Payloads to Ordnances to prevent confusion with ship Payloads.
--- Numerous bug and crash fixes. Notable bugs include: Temporal Burn Dragger no longer deletes previous burns, dozens of small material and chemical reaction tweaks, radiators start out cooler in combat if you have more than enough, ship design no longer stacks heat and power incorrectly.

About This Game

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.
