Kingpin: Life of Crime Hints & Cheats

Edit the file AUTOEXEC.CFG (found in Kingpin's ''Main'' directory) and add the following line:
set developer 1

You may now enter the following codes by pressing the single quote (`) key while playing and typing the desired code in the console window.

Enable the console by using this command to create a shortcut : c:\kingpin\kingpin.exe +developer 1. Run the game from this shortcut. Once in the game, press the ~ key and type these commands to automatically go to these levels.

The secret weapon in the Kingpin demo, which was mentioned in the readme file, is the flamethrower! To get the flamethrower, go to the place with the old car in the map SR3. After you killed the dogs and picked up the battery, jump onto the roof of the car and shoot it. Then bang on or shoot the bottom until it breaks, revealing a box. DON'T SHOOT IT! Instead, bang on it with the crowbar or lead pipe to pick up the flamethrower. Now that you have it, go NUTS! But be warned: there's only 50 flamethrower ammo to be found.
