The Berlin XVIII core rules are split in 3 booklets, held together by the 2-panel gamemaster screen.
The first rulebook contains the Universom standard rules explained in 9 pages (stats, skills, the combat system).
The second booklet details the Berlin XVIII universe: historical summary, maps of Europe in 2070, descriptions of Berlin, the different gangs, the different police forces, how justice works... There are also the character creation rules and a list of available gear (weapons, vehicles...)
The last booklet, a scenario ("Auslander") is a serial killer hunt with a twist. It serves as a player introduction to the life of a Falkampft (police procedure, scientific police work...).
