Scarface: The World Is Yours/Sun Ray Hotel

Call a fast car and park it at the foot of the stairs, you'll need that for later. Head on up to the dealer's room. After the cut scene, quickly take out your gun and shoot the guy that is fast closing in on you. Now take out the rest that should be hanging out outside the room. Get in your car and give him chase. He's got a really fast car, so keep up. Keep shooting his car until it explodes. If you don't destroy it before he reaches the trailer park, he'll get a helicopter and you'll have to cross over a load of ramps and then shoot him while he's firing back at you, so it's best to kill him before that. However, if you don't and you have to take him out in the helicopter, get out of the car and keep moving while you shoot him. Be careful, as he has a grenade launcher.

You can now buy the hotel for $5,000,000.
