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.

Billboards
Unlock the P.L.A.V. faction and get a gunship with rockets, such as a Castro V Attack chopper or an Anaconda from the pirates (recommended, as it carries about 80 rockets). Fly to the city of Merida and shoot the billboards. You will earn $5,000. If you shoot enough of them you begin to unlock more shop items from the P.L.A.V. and a few things from the U.P. mercenaries in their city. Only one rocket is required to destroy a billboard. It only takes 1 rocket from a gunship to destroy those pesky billboards.

Capturing outposts quickly
When 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 start to smoke and two helicopters will appear. This will speed up the process when you are getting shot or are in a tight situation.
Defeating 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 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.
Easy money
After completing the first UP mission and receiving Ewan, talk to him about the Winch 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 about four times (depending on how much you start with), you should have about $7.0 million. You can continue from here in order to get the maximum wager amount to $5.0 million (when you have about $14.0 million in funds). From there you can repeat this as often as desired when you need money.
To save time, if you are trying to use the above method to increase your money, use stackable items from outside of your stronghold. 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 stronghold 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.
Also regarding the bet amount, once you go over $10 million, it only gives you $1 million and slowly increases.
Find a Cash Bundle out in the field. Make sure you are in an area with lots of open room. If not, call in a helicopter and take the money to a safe place (for example, the PMC air strip). Tag it and call it in. When Ewen picks it up and you are credited for the find, shoot the money crate. You can do this by any means necessary (for example, use a nearby armed combat chopper, wait for Ewen to get there, then shoot the crate after getting the credit). Money should rain down on the ground around you. Run around and collect it all for an added bonus of roughly $50,000. The bits that scatter across the ground are worth about $5,000 each.
Once you have obtained your helicopter pilot, he will supply a bet, wagering that you cannot stack enough things to get the toolbox above the displayed height. This wager is easy and the money goes up by about $2,000 each time you play.
Easy transport and smuggling missions
Note: 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 start. 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.
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.
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.
Pick-up multiple items at once
Go to all the items you want to pick-up that are in range and select them all. Once all items are selected, throw your resource pick-up smoke. The helicopter should pick-up one item, but all other items will disappear letting you know you have them. You may get an error message stating "Unable to at the moment" or something similar, but the items will still be collected.
Repair vehicle instantly
Park your vehicle outside of a building you can enter. Enter the building and exit. Your vehicle should now be completely repaired with full ammunition.
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. Note: 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. Spending 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. Note: 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.
Fly a chopper with a winch. Winch a car and throw it on top of other cars to destroy them.
