Grand Theft Auto IV/Bernie

Hating the Haters
Head over to the jogging area. Follow Bernie but keep your distance until he reaches the tunnel. After Bernie gets battered, chase his attacker up the stairs. He will flee in a Faggio. Steal one parked on the left side of the road and chase him. Do your best at shooting him. An SMG is recommended. If you're having a hard time taking him down, just keep following him. Bernie will eventually wait at the entrance you Bernie came through at the start of the mission. Pick him up and continue catching up on the attacker. After neutralizing the attacker, go to the end route marked on the map.
