Formerly a thriving habitable planet of civilization, Earth's landscape has undergone some massive changes since the Astral Gate Disaster of 2022. While most of the survivors escaped to other planets within the Solar System, few remained on Earth, living in typically ruined settlements or underground structures. As for the landscape itself, there seems to be no recognizable aspects from what Earth looked like before the Accident. The once habitable terrain is now filled with ruined cities and rock deserts, though there are still oceans around. Despite this, the 200 million people of Earth maintain a semblance of society and order, even sixty years after the Accident. Instead of countries and states, most of Earth is now divided into sectors.
On a side note, pay attention to the forecast, and be careful when you go outside. You never know when a Rock Shower could occur...
