How to Enter Cheats
Go to the main menu and use the directional buttons to highlight the "Trail by Trucking" option. For the PS2 version, press "Circle" to bring up the cheat menu. If you are playing on an Xbox, push the "Y" button for the cheat menu. The PC version requires you to select ""Trail by Trucking" and then enter the "Cheat Menu." Once you are in the Cheat Menu, simply enter a code to enable a cheat.
Rich and Indestructible
Input the cheat code "NODAMAGE" to make your vehicle invulnerable to any form of damage, whether that means bullets from an angry armed biker or accidental damage caused by crashing your truck. The cheat code "CASH" is used when you are a bit low on money, or even if you have plenty of cash, but still want more. Each time you enter it you receive a $115,000 boost to your balance.
Add or Remove Police Cars
In "Big Mutha Truckers 2" you can earn extra money by smashing into vehicles as you travel down the highway delivering goods. The problem is that the police also drive on these roads and even clipping a police car will get you arrested, resulting in a loss of cash. Enter the cheat code "NOCOPS" to completely remove the police from the roads, so you can drive like a maniac with no consequences. Alternatively, you could add more police to the roads for a challenge by using the "COPS" cheat.
Other Cheats
Not all of the missions are available at the start of the game; they are added in time. If you can't wait that long then enter "MISSIONS" to unlock them all. Some bridges in the games will be blocked off; input the cheat ""BRIDGE" to every one of them. Bikers are gangs in the game that will fire at your truck if you anger them. To add an extra challenge, enter the code "BIKERS" to increase their numbers.
