The story of this game revolves around years 1987-1989 during the political changes in Poland (from communism to capitalism) in Polish city Szczecin. Main character's friend - Alex - was attacked by some random bald guy and knocked out, when Franko decided to strike the guy back, guy's "friends" appeared and kicked the s**t out of him...
Thus begun holy quest of walking through the not-so-pretty block of flats districts of Polish city and killing everything that moves (including all popular sub-cultures of the '80s, judo fighters, as well as police, MO and ZOMO officers). You can choose one of two available characters: Franko or Alex (even though according to game story the latter got killed - slight mishap) that differ in strengst and fighting style.
There are 3 major bosses at the end of each stage, between stages you move by driving Fiat126p (the car called "Maluch" - the icon of Polish pop-culture of that time). Story of the game reveals some smuggling affairs (Szczecin is a harbour-city) as well as the events of political transformation as the game goes by.
