Liberiko is a futuristic multiplayer shooter set during a global civil war between Liberiko and the Reavers. These two factions are trying to make sense of a world in ruins hundreds of years after a event horizon that led to the fall of civilization. This conflict involves two brothers with vastly different ideas as to how the world should be rebuilt.
This is a concept of a Liberico settlement which is based in Underground Tokyo, if you wanted us to be more specific it is in "Tokyo’s Drainage System" where the Kane Reaver patrols do not go through to far in.
