Double-Cross Crush!, also known as Gang Car Bang! is a mission in Grand Theft Auto 2 given to protagonist Claude Speed by Redneck boss Billy Bob Bean. The mission is available from the top of the two green Redneck phones in the Mobile RV Park of the Residential District.
The Rednecks are annoyed with the Zaibatsu and SRS so they hire Claude to start a gang war by killing 50 (20 on PlayStation) of each gang with their rival's gang car.
The reward for completing the mission is $30,000.
