Start your mission with a friendly talk. See how Sheldon is doing. He seems nice and relaxed. That’s great and all, but you can’t afford to sit back; things are about to go down close by, and you have to be there.
Defeat the Reinforcements
Jump into the nearby rebel chopper and fly toward your objective. You have both missiles and a minigun to work with, and your targets are a series of heavy military ships that are speeding toward your buddies.
Don’t get too high in the air as it reduces the accuracy of your missiles if they have to travel really far. Get closer to the water and strafe the heck out of your victims. You want to drive those missiles right down their necks.
There are occasional helicopters patrolling to defend the navy. Make sure to attack the choppers as soon as you see them, because losing your own gunship makes this mission much more difficult.
Reach Mario and Dimah
As soon as the third ship is destroyed, you can start to see Mario’s position. Fly over there and take out a SAM site on the way (look for the red light over the missile battery so that you don’t miss it). Once the SAM site is down, attack the ships that are going after Mario and Dimah.
Ditch your chopper when the coast is clear, and grapple your way into the rebel boat with your allies.
Check on the Informants
Pilot the boat around the coastline and check on some informants. There aren’t any enemies at the first site, so continue on toward the next objective marker. You pass through a minefield on the way there. Either maneuver in between the mines, or try a turbo jump with your modified boat.
Check out the small island at the second site, and then turn the boat around to hit open water and go around to the final informant location. It’s there that you meet Annika and Teo. They become part of the cause (for a buck or two).
Talk with them for a second, and then hurry back to the docks to repel enemy soldiers that attack.
Protect the Rebels
Commandeer an enemy helicopter that comes in, and use its minigun on the ships and trucks that pull up.
The nastiest threat comes at the end of the mission; another heavy ship pulls toward the harbor. Its guns are mean, and the ship is likely to take out any aircraft or boats that you’ve been using to defend the rebels. Should you lose your craft, grapple onto the big vessel, deploy explosives from the rear of the ship, and blow the target up while you’re safe. Never stand in front of the ship or to its sides. The gun can rip you open without missing a beat.
As soon as the big ship is destroyed, you’re done. Watch the end scene of the mission.
