Scarface: The World Is Yours/O' Grady's Liquor Store

Hopefully you'll have an AK-47. If not, it'll be slightly harder for you. The general aim of this is to stop the attackers from breaking the stock, so try not to help them out in that regard.

The first wave of attackers will come by the front entrance, and you'll make short work of them. The next will come from the side entrance, so get ready and take out those guys before they can even get in the store. The third wave will come around the back and come in from the back door and the front entrance. Use blind rage at this moment just to stop yourself from being overwhelmed. After you've taken out those guys, you'll get a message saying "they're closing in". A couple will come in through the front entrance and the back door, but the main worry is the guys that come in through the side entrance – they're all equipped with shotguns, so if they get too close they're going to make short work of you. Once they're dead, talk to the manager. Note that there is health behind the counter and in the back room if you need it.

You can now buy the store for $120,000.
