The Settlement Defense Front (SDF) is a group of brutal and militant radicals, that broke of from UNSA in a war for independency. They are your chief enemy, and their design should reflect their opposing ethics and convictions. This is the commanding bridge on their main destroyer.
The SDF elevator on mars. The pillars anchor the tension from the cables reaching out into orbit. The early version (bottom) had a more flat profile.
