Evaluation
Children of a Dead Earth launched on September 23, 2016 as a complete, finished product — a scientifically accurate space warfare simulator with a full campaign and sandbox mode. Following launch, the developer (Q Switched Productions) was quite active, shipping a steady stream of substantial feature patches through mid-2018: Patch 1.0.6 (October 2016), 1.0.7 (November 2016), 1.0.8 (December 2016), 1.1.0 (March 2017), 1.1.1 (April 2017), 1.1.2 (June 2017), 1.2.0 (December 2017), and finally Patch 1.2.1 (July 1, 2018). These updates added meaningful new features — Steam Workshop support, a level editor, new weapon systems, expanded ship design options, localization support, and much more — reflecting genuine commitment to improving the game post-launch. However, July 1, 2018 marks the last recorded developer communication of any kind. No news posts, patches, DLC announcements, or roadmaps have appeared since then. There are no unreleased DLC items on the store, no announced future content, and no developer statement about plans for additional updates. The game has no live-service or seasonal content structure. Given that the update pattern ended cleanly with Patch 1.2.1 and the developer has been silent since June 2018, the game is best understood as having reached a natural conclusion of its post-launch support cycle at that point. The store description reflects the game as a complete package, and no outstanding commitments remain.
Evidence
Patch 1.2.1 released, adding a fully featured level editor, wedge ship armor, multibarrel guns, multiengine gimbals, and many bug fixes. This is the last recorded developer update.
Patch 1.2.0 added foreign language support, concave and polygonal ship armor, fuse modules, grid view for designs, and ship shadows.

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.
Features
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.

Features
- 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.
