Full Changelist

1.2.1 (6/1/2017)
- Level Editor
--- Levels, factions, celestial bodies can all be edited and put together into a single campaign, which can be exported to Steam Workshop and played by other players.
--- Existing celestial bodies and factions can be reused, or new ones can be created.
--- Can customize celestial bodies' ring textures, body textures, body model, or can create new bodies which reuse core game textures, models, etc.
- Design
--- Wedge Ships - Ship armor aspect ratio can be modified to yield flattened ship shapes. Only for non-cylindrical armor.
--- Multibarrel Guns - Projectile weapons can have many guns per turret, which can distribute heat and provide scatter fire patterns.
--- Preloaded Cannons - Conventional cannons have all munitions preloaded now, so with multiple barrels, can act as a turreted blast launcher.
--- Multiengine Gimbals - Engines can be stacked many to a single gimbal. This allows very dense rockets, and much higher thrust per area.
--- Space Efficient Attaching Modules - Attached modules fit better. For example, with two propellant tanks side by side, weapons use the space above and below better than side to side with the tanks.
--- Dodecagonal Cross Section - Twelve sided ship armor, which functions as angular but near-circular armor.
- Gameplay
--- Instant Action - New option in Sandbox which starts both fleets out in combat at their max weapon range.
--- Can now use missiles or drones directly in Sandbox.
--- Guns start combat already aimed at their target. Very useful for large, slow-turning guns.
--- Some AIs have the option to ignore range for launchers.
- UI
--- Mod Designs, User Designs, and Core Designs are split apart in lists for easier reading.
--- Option to watch the ending from the briefing menu if you've beaten the game (due to a bug that may have disabled the ending previously).
- Mods
--- Can switch between campaigns in game.
--- Exposed more properties in Limits.txt, including the total number of armor layers allowed.
--- Mod resources and Steam Workshop Items with now have priority over default resources with the same name, including Audio, Textures, Models, and Fonts.
--- Steam Workshop - All resource files can be read in from Steam Workshop, including font files, so language conversions can be loaded from Steam Workshop without any extra steps (if it has the font files).
- Other
--- Countless bug fixes, including missiles exploding as soon as they launch, Blast Launcher being able to reload, incorrect armor mass with partial armor, numerous typos, some material property fixes, ending not playing properly, Saturn's rings rendered wrong, and many, many more.
--- Countless crash fixes.

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.
