Army of Two Tips

Easy Money In China
This cheat would be very easy if you have already beaten the game (recommended). Before you even start campaign you must do the following: First instead of starting a new campaign go to select map and choose the level China. In the beginning of this level there is an objective that you must destroy the convoy as it goes over the bridge, kill the soldiers and go down to the part of the map where you destroy it. After you kill the convoy you are awarded $30,000. Once you get the money run back down to your hovercraft and wait until the characters finish the other dialog about the bounty on your head. When they finish pause the game and press quit game. Then repeat these steps until you get the money that you desire.
NOTE: you may have to change difficulties from time to time when you want to play the level.
