GTA IV- "Chain Reaction" Achievement

Here is how to get the "Chain Reaction" Achievement. You must find a bus. There should be some on the main street near Launcet in the middle of the third island. When you find the bus, go to the nearest bridge. Drive onto the side with on-coming traffic for the most vehicles. Then turn the bus so it perfectly blocks the road from cars being able to go around. Jump ontop of a car next to the bus and then jump onto the bus. Bring out your weapon of choice and aim in in the middle as soon as ten or more cars are piled up. Once you blow up one car, jump off the back of the bus so you don&die from the explosion. Wait for the chain reaction and recieve your achievement. Gamertag: LuckyIrish423 Music: Rammstien- Feuer Frei
