Operation: Matriarchy is a science-fiction first-person shooter set in the 24th century, when humanity has formed the Federation of Earth and colonized other planets. Its conflict begins on Velia, where a mysterious virus targets women, transforming them into killing machines while men are enslaved.
The transformed Velians have evolved into an aggressive hive mind and turn against the Federation. The game opens seven years into the war, with Federation Senior Sergeant Paul Armstrong forced to fight back when the Velians attack his ship. This frames the action around a soldier caught in a larger interplanetary conflict.
Its distinctive premise combines an alien-virus outbreak with a society reshaped by the infected and a war against the Federation. The available account establishes the first-person shooter perspective and Armstrong’s opening predicament, but does not detail weapons, mission structure, or other specific mechanics.
