Mission objectives: President Mendoza has escaped to his very own island. As you've probably suspected, this entire area is heavily guarded. You will have to infiltrate it and locate the president. There are a lot of Black Hand units there. You will have to deal with some of the leaders of this elite organization. Both Guerrillas as well as Riojas will provide much needed help during this mission.
This is by far the most difficult mission of the entire game. I'm almost certain that you won't finish it without having to repeat most of its segments. Additionally, some of your victories may be accidental, mostly because you won't be able to know in what way will the mission progress. You should also know that the game will create only a few necessary checkpoints. As a result, you will have to repeat a lot of difficult fights. I will try and show you one of the safest routes, that should allow you to finish this mission without any unwanted delays.
Make sure that you're well armed before you decide to proceed with the mission! You must have a rocket launcher with you, as well as a machine gun. Start off by going to the briefing area (#1). Once again, you won't find anything of interest here. Press the correct button and wait for the allied helicopter to show up (#2). Get inside the gunship. Sadly, you won't be able to control where you are going. A new cut-scene should appear on your screen. Listen closely to what Sheldon and Kane have to say.
Once you've been briefed, you should notice that you're still in the air. Sadly, you won't be able to use this helicopter. The only thing left to do here is to make a jump (#1). You don't have to use the parachute. Either way, you'll end up in the water. I would recommend that you put a request for a boat (#2). You will have to use the Agency screen in order to do that. You should also be in a lot of hurry, because enemy gunships are patrolling this entire area. If you lose too much health, make sure to go back to the previous checkpoint and try again.
Your first main objective will be to reach Mendoza's palace. Sadly, it's located in the central part of the island, so it won't be easy. Use the boat to get closer to the island. You will also have to pick a correct spot from where you'll proceed to the main land (#1). You'll find yourself in the woods. Make sure you're running towards a nearby road (#2). You will probably encounter a few soldiers along the way.
As you've probably noticed, Guerrillas and Riojas are fighting with Black Hand units (#1). I guess I should warn you about something. There are a lot of helicopters and fighters in the air. You should be very careful. Most of the jets will fire rockets against you, even if you're not using any vehicles at the time. As a result, you will have to try to avoid most of these attacks. Make sure you use trees and other large objects (except cars) for much needed cover. You will have to steal one of the armored trucks. Make sure that the vehicle is well equipped (#2). You might also consider shooting down some of the gunships first, so you won't be attacked after stealing one of the vehicles.
Now you will have to start driving towards the palace. Make sure that you're moving FAST enough. You CAN'T stop at nothing. Otherwise your vehicle would have been probably destroyed. You should also avoid other vehicles, as well as larger groups of enemy soldiers. You could try and kill some of your opponents (#1), however this is very risky. Make sure that you reach the palace as soon as possible (#2).
You will have to get closer to the main gate. Once you're there, turn left and enter the palace area (#1). Make sure that you don't hit anything along the way. You will receive some new orders in just a few seconds. You must destroy one of the enemy tanks. It's being occupied by a commander of the Black Hand units. Start moving towards your new target (#2). Also, make sure that you don't get hit by any of the missiles. You'll need this vehicle in the future!
You will have to destroy this tank (#1). Remember that you have to keep moving. Otherwise you will surely be hit, either by the tank crew or one of the helicopters. You should also position yourself correctly. Rear side of the tank has a much weaker armor. Thanks to that, you will be able to destroy it much faster. You will have to get rid of this problem in order to proceed to the next section. A short cut-scene should appear on your screen (#2). President Mendoza has left the palace. He is now hiding in a nearby villa. You will have to go there. The game will create a checkpoint here. Make sure that you're inside an armored vehicles when that happens.
This is the most difficult part of this mission. I would recommend that you choose my path to the villa (#1). It doesn't mean, however, that you'll be able to reach it without any problems. You must avoid all types of attacks. There are a lot of armored vehicles, fighters and helicopters in this area. First of all, you will have to exit the palace. Turn left and start moving forward. Ignore EVERYTHING that happens around you. DON'T even think about stopping. Shoot only at these units that will actually try to destroy you.
I should tell you that there's ONLY ONE path leading to your destination. You have to choose it correctly (be sure to check the map often). Otherwise you would have to go back, because you wouldn't even be able to climb up to your target. Make sure that you don't miss it (#1). There are some new vehicles here (#2). Thankfully, you should be able to avoid most of them. Concentrate only on reaching the villa safely.
Watch out during the final phase of your approach. The road gets very narrow here (#1), so it easy to make a mistake. You must stay on this road at all costs. Also, watch out for any larger objects - trees or even rocks. You should be able to reach the villa in a few minutes. There's a small road here. Use it to get to the top (#2).
A new cut-scene should appear on your screen (#1). Mendoza will escape you once again. As a result, you won't be able to kill him during this mission. Exit the vehicle quickly. Step up to the huge cliff and make a jump. Once you're in the air, use your parachute (#2). Start heading towards your final target.
You will have to use the directional buttons in order to steer the parachute correctly (#1). Your objective is a nearby airfield. Make sure to use the upper movement key, so you'll accelerate a little. It's very important, because there are a lot of enemy gunships in the area. They will try to kill you. Make sure that you land safely (#2). You will have to reach a designated area of the airfield. After that, this mission will come to an end. You should also know that you won't have an opportunity to rest here, because the next mission of the campaign will begin automatically.
Important! I guess I should warn you that two of the remaining missions won't allow you to visit any of the surrounding hideouts. As a result, you will have to be very careful, mostly because you probably lost a lot of health in the previous mission.
