Scarface: The World Is Yours/Felix

Head down to Coco's. After the short cut scene, you can get to grips with dealing coke. Here you have to hold to fill the meter until it gets to the end. Go too far and you've failed, don't go far enough and you either fail or get a rubbish deal.

Now go try it for real. If you get a good deal, you should get $10,000 which is the right amount to buy back your mansion. Get back to your mansion and pay off those pigs.

Reputation upgrade #1
Head on to your newly acquired mansion, and in your office you can see what has been unlocked.
 * 14 new Exotics are unlocked.
 * $5,000 drug suppliers have been unlocked.
 * The Micro SMG has been unlocked and can now be purchased from weapon dealers.
