Dead Men Dump Truck Madness
Having trouble killing the driver of the dump truck in the junk yard? Apparently, all you need to do is shoot the pilot's cockpit with gunfire. Once the glass breaks, you stop the truck automatically. Do it quickly, since the dump truck will automatically kill Jenny on its second pass.
Freedom Fighters: Easy completion
When you are at the spot where you have to proceed to El Capacito, tell your men to go to the big pointy statue in the center and take cover. Then, proceed to shoot down the helicopter first before continuing. A few RPGs will be required before it will go down. If you run out of RPGs, go back to the previous spot where you had to shoot the APC vehicle to get more supplies.
