Call of Duty: Black Ops walkthrough part 11- Crash Site
Mason, Woods, Reznov and Bowman hear of a Soviet transport plane which was shot down by the C.I.A carrying Nova 6. So they join a PBR task force and help them destroy ZPUs and other structures. Then they make their way to the plane fighting Vietcong and destroy an NVA patrol boat, but their marine gunner is killed in the fighting. They reach the crash area and fight through more Vietcong and Russian Spetsnaz as their Hueys are shot down by Hinds. When the fighting is done, they reach the plane, they discover that the crew did not die in the crash, but when the Nova 6 was released. They discover that they also have American weapons in a cargo crate and are attacked by more Vietcong again, they make a stand in the plane and fight, but it is destroyed by more hinds. The team survives, but they are captured by the Spetsnaz.
Note: I know that there is a certain song playing during the boat part of the mission, but I never intended to copyright, this was only for fun.
