The game lets players control the mute criminal Claude. During the story, Claude meets various new characters from gangs. As players complete missions for different gangs and criminal organisations, fellow gang members will often defend players, while rival gang members will recognise players and subsequently shoot on sight. While free roaming the game world, players may engage in activities such as a vigilante minigame, a fire fighting activity, a paramedic service and a taxi cab service. Completion of these activities grants players with context-specific rewards; for example, completing the vigilante mission allows players to bribe police after committing a crime.
