---Side with the Federation, or the Empire? Or intervene alone to end the war?---
Universal Century Year XX. Earth is locked in a cycle of perpetual warfare. Technology has advanced, and the fires of war never cease, fueled by Mobile Suits evolved through modern engineering. Support is split evenly between the Federation and the Empire; with no clear sense of who is just, both sides continue to seize territory and military strength from one another. One ordinary day, Guest is caught in a battle while out in the city. Fleeing to the mountains, you discover a cave. Deep inside, a white Mobile Suit covered in black cloth makes its eyes glow. Federation Rules the Northern Hemisphere of Earth. They use modern customizations of legacy Mobile Suits like the GM and Guncannon as their main mainstays. They possess a large fleet, with the flagship Arch Horse serving as their greatest military asset. Empire Rules the Southern Hemisphere. Rather than rule by force, it is home to those who oppose the Federation's intentions. They primarily use Mobile Suits such as the Zaku and Gouf. While they lack a fleet on the scale of the Arch Horse, Catalina's Neo Queen Mansa is the strongest among all Mobile Suits.
