Children of a Dead Earth

Earth's atmosphere collapsed under runaway greenhouse warming. The survivors moved to the inner planets and moons of the solar system, establishing two competing power structures: the United Sol Trade Alliance and the Republic of the Free People. The tension between them is now a full military conflict. Children of a Dead Earth is a space warfare simulation built on real orbital mechanics, real materials science, and real weapons physics — every ship, projectile, and engagement modeled as accurately as the underlying science allows.
