Legacy Guide Introduction (2001):

You have never played anything like Grand Theft Auto 3... after picking it up, you may never play anything again. Grand Theft Auto3 is all about possibility. At any given point in the game, you can do one of a million things. Listen to the radio. Car jack someone. Double-cross the mob. Give someone an illegal taxicab ride. Or just beat on him with a bat. If you can think it, you can pretty much do it... that's the beauty of the game.

Since GTA3 is so non-linear and missions can be completed in orders other than listed, we suggest sticking to one boss at a time until all his jobs are exhausted or you no longer can take the job without completing another (like Toni and Salvatore in Portland). We have provided optional tips on missions that have unlimited solutions, which is true for most since there are numerous ways to off someone or destroy something. In other words, you don't have to stick to the guide, but if you get stuck, we have solutions that work. Enjoy.
