- Overcomeing Carmona
When Carmona's men are attacking the PMC, after you destroy the tanks, set a charge of C4 on the gates closer to the mansion, and detonate it. It should drop straight down and block the road leading out of the compound. Enter the mansion, and trigger the intermission sequence. When you exit the building, the road leading out of the compound will still be blocked. Kill Carmona's bodyguards, and his jeep should be stuck in the rubble of the archway. Kill him, and snap the picture for easy verification of Carmona.


When completing the mission on the oil rig in the water behind the PMC, kill Blanco and take his weapon, the hunting pistol. The hunting pistol is a very powerful weapon, often killing enemies in one shot. With the hunting pistol in your possession, continue through the 'Finding Solano' mission. After the encounter with Carmona inside the Villa, he will run in a straight line directly away from you, giving you a clear shot at his back. If you miss on the first shot, he has a good bit of a jog until he reaches his jeep, giving you plenty of time to gun him down.

- Easy 'Hail and Kill', 'Holy Smoke', and 'Little Savage' achievements
Go to the courtyard behind PMC HQ (the villa from the first mission) to find several destructible objects that respawn, which you can use to easily get the 'Hail and Kill', 'Holy Smoke', and 'Little Savage' achievements.

- Bonus equipment
Successfully complete the indicated task to unlock the corresponding equipment:

Diplomat heavy tank	Destroy the targeted buildings for the Allied Nations.
Ambassador gunship	Successfully complete level 3 of the Helicopter Flying mission.
MOAB bomb	Successfully complete all HVT missions for the Allied Nations.
Nuclear Bunker Buster	Successfully complete the final contract mission, 'Get Solano Part 2' to unlock it for purchase from Eva for $1 million.

- Easy money
After completing the first UP mission and recruiting Ewan, talk to him about the Be victorious inch challenge. After completing level 3 on this challenge, bet the maximum amount of money. Even though you have already done this, the height does not raise. Therefore you can continue betting at the maximum amount. After approximately four times (depending on how much you begin with), you should have about $7.0 million. Continue from here to get the maximum wager amount to $5.0 million (when you have about $14.0 million in funds). Repeat this as many times as desired. Additionally, when you get the maximum betting level on the Be victorious inch challenge, keep going until you get to approximately $100 million. The minimum bet will now also be $5 million. If you continue from there, the minimum will actually grow higher than the maximum and allow for even more money. However, once the minimum goes beyond $5 million, there is no way you can raise or lower the bet because it is higher than the maximum, but it is still the minimum. Notice: To save time in the Be victorious inch challenge, use stackable items from outside of your strongkeep pushed. For example, try the gas canisters across the road (or for something less volatile, use the shipping containers directly across the lake behind your house). Items used from outside of your strongkeep pushed stay in the exact location you put them until you quit your game, giving you a prepared stack height the next time around. Two or three attempts may be required to gather the items, but it is well worth it, as once done it requires only seconds to win the challenge.

- Easy challenges
Bet the maximum money for the level 1 and 2 challenges, then save and reload the game until you win. Bet the minimum money for the level 3 challenge.

- Alternate costumes
Successfully complete a level 3 weapon challenge at the PMC Villa with Fiona to unlock the corresponding costume in order for the indicated character. There are a total of three costumes for each character. The Pistol challenge is the easiest to complete. The Emplacement Weapons and Grenade Launcher challenges are about even; however, Emplacement Weapons is slightly more difficult when you have to shoot the flying cars. The Sniper challenge is the most difficult to complete.

- Easy transport and smuggling missions
Notice: This trick only works after you have obtained a helicopter pilot and the winch ability. When on a transport or smuggling contract that relies on you not tipping the vehicle and losing the objects inside, summon a helicopter as close to the vehicle as possible before entering the mission assigned vehicle. Then, enter the mission vehicle, and the timer should begin. Get back out, and take off in your helicopter. Use the winch to grab the mission vehicle, and gain as much altitude as possible. If you fly relatively level, you will not lose anything. However, if you bank even slightly to get around obstacles, losses will be minimal as long as you do not actually bank the copter in a hard turn. The vehicle will get tossed around, making the copter harder to fly; but if you travel directly to the drop-off point from the beginning, it will keep its cargo. This helps you avoid nearly all ground forces. All you have to worry about are the anti-air guns and other helicopters. If worst comes to worst, simply drop the vehicle after coming down to about 20 feet or less. You will have already have saved enough time to hijack another helicopter.

- Sniper rifle scope on regular rifle
Have a sniper rifle in your inventory. While you are using the scope, press D-pad Right to switch weapons. You should have an assault rifle out while having the scoped view.

- Getting 100% completion
Successfully complete all outpost missions before you initiate the final mission in Story mode. The outpost missions can no longer be accessed after the game is completed, which will also prevent a faction's shop items from being unlocked.

- Stealing fuel without upsetting a faction
This is most useful when used with factions who are already hostile (to keep them from shooting you down), but can also be used to keep friendly factions from becoming upset with you. Get one of the helicopters used by the faction you want to steal from (or one of its allies), and allow your disguise to finish. Fly to the location of the fuel you want to get, and lower your winch. Grab the fuel tank, and lift off before the enemy soldiers recognize you, then fly to a secure location (either the PMC or a remote, open location). Once out of sight, call Ewan in for the pick-up. Notice: Using a heavier helicopter is recommended, as the Rogue and Gunney class choppers are extremely difficult to control when carrying a heavy fuel tank. Also, there are at least half a dozen fuel tanks relatively close to the PMC, most of which are controlled by Universal Petroleum. Paying the fuel for an Ambassador Gunship (an Allied helicopter, who are allies with UP) is well worth it if you are going to use your PMC as a fuel depot.


Use the following trick to steal fuel from a friendly faction without having to worry about affecting their status towards you. Go to an outpost that has fuel tanks, and tag them. Then, call in Ewan for the extraction. If a soldier happens to call in a report about your hostile act, go inside the outpost to cancel the call. By doing this you will get fuel and the faction will still be friendly with you.


This trick requires a fast vehicle (for example, a sports motorcycle). Find an outpost that has a fuel tank. Look for an easy way out before you attempt to steal the fuel. Once your vehicle is positioned facing the fast exit, and after making sure no one sees you, tag the fuel tank, and call Ewan for extraction. Run to your vehicle, and drive as fast as you can until you are far enough from the place so that no one can report you. Notice: This also works with a helicopter as your vehicle when you are in the jungle area, but requires more time because you must wait a few seconds before you can lift off.

- Capturing outposts quickly
While playing in Co-op mode with a friend, look in the same direction at the same time. Throw the signal smoke to call in for reinforcements to capture an outpost. If done correctly, both of the thrown signal smokes will begin to smoke and two helicopters will appear. This will speed up the process when you are getting shot or are in a tough situation.

- Easy vehicle repair
Park your vehicle outside of a building you can enter, then enter the building and exit. Your vehicle should now be completely repaired with full ammunition.
