The 6th Street are a gang in Cyberpunk 2077.
After the 4th Corporate War, a large number of career soldiers were left without jobs or prospects - the most enterprising of them formed the 6th Street Gang. Not only do they boast veterans among their ranks, but also ex-police officers, former corporate security agents and "civilians" who have had a crash course in combat training - everyone and anyone who wants to bring order to this town.
The end justifies the means, and the means usually involve robberies, extortion, arms dealing and stealing cars. Their main turf is in Arroyo, but 6th Street's garages and bases of operation can also be found in other parts of the city.
