Drug Wars: Underworld Money Cheat:
Buy 1 of any drug when it's at it's cheapest, for example - 1x ecstasy for £17
Then go to the right of the screen and click on sell and where it asks you how many you want to sell,
Type in the highest possible number (just type as many 9's as possible). You will then have a huge amount of money (especially if you sell cocaine).
But what happens now is your storage space goes into minus, like -100000000, making it impossible to buy any more drugs or make any more money.
So what you do then is deposit the money you've made into the bank and then when the police come, click on surrender and your storage space will return to normal.
You will lose any guns etc. but that doesn't matter.
