At the end of the last level, use the following method to easily defeat the final group of mercenaries protecting Doyle at the top of the stabilizer. Slowly approach the ramp until you hear the radio chatter confirming they have spawned above you. Then, back up and look towards the large fuel tanks. You cannot see them, but the mercenaries are gathered around and behind these tanks. Throw all of your grenades at the tanks to easily kill or wounded almost all of the mercenaries, leaving just one or two to kill upstairs.Driving pigs
Park a buggy in an unsafe location (for example, on a flight of stairs in the Fort level). Eventually a pig will get in and drive the buggy and park it back on the road. Note: The pig will run you over if you are in the way.Achievements
