Infamous Gangsters is an online game where you start as a hobo and work your way up through the criminal world. One factor in the game is money: To get to bigger levels and jobs, you need money, and in several parts of the game, you need to get it quickly. There are several simple ways to do this, depending on your current income level.
Commit all the crimes you can. The amount paid is somewhat random but does depend on the level of crime--the higher level the crime, the more money you earn.
Buy and sell back alcohol. Each city has a different buying and selling price for alcohol. If you buy alcohol cheaply in one city, you can sell it to another city with a higher price and make money.
Gamble at the casino. Bet 60p on Blackjack the first three hands, then bet a lot of money on the fourth hand. You will win the fourth hand about 80 per cent of the time.
Buy cars in one city, then sell them back in another. How much you make depends on the availability of the cars at the time you sell. This works best with the most expensive cars, such as the Ferrari Enzo and Lamborghini Gallardo.
Bust people out of jail. Every person you bust out of jail will pay you back. The biggest payday is Sam, who will give you £1.6 million if you bust him out of jail.
You should buy wine in Berlin and sell it in Moscow; buy beer in London and sell it in either Moscow or Amsterdam; buy rum in London and sell it in Berlin; buy whiskey in Berlin and sell it in London; and buy vodka in London and sell it in Berlin.
