San Andreas Mercenaries: Project Overthrow - Unconventional Warfare Guide

When you land, switch to a suppressed weapon and take out the guard. Always aim for headshots.

After eliminating the guard, use the ladder to go down and continue moving toward the server farm entrance.

You will find two more guards here. But before taking them out, keep an eye out for a patrolling guard who can see them.

Luckily, we got to the two guards first. You can see the patrolling guard on the minimap and through the gate as we move forward.

If the guard reaches the gate, wait for him to turn around before you can go in front of the gate.

Once turned around, quickly go and take him and the guard on the left out.

There's another guard across the trash container. You can take out this guard as well if you want. But there is another patrolling guard right next to him. So, be careful before you take him out. The safest bet is to leave that guard alone.

Use the keypad to unlock the door and enter the server farm.

When you're inside, carefully take out the guard at the bottom and follow the route by going right.

Another guard is patrolling the route on the right. Wait for him to turn around and take him out before continuing down the path.

Go through the server compartments for some extra protection. Keep your eyes on the minimap as you move through these compartments.

As soon as you see a large cone of vision, pre-aim in that direction and take out the guards looking your way with a headshot.

Following the same strategy, continue moving forward until you reach Avi.

Take out all the guards around Avi and approach him. Now, you take the same route back while eliminating any incoming enemies. Once you get to Avi, the guards will be alerted. You cannot sneak your way out.

Do not leave Avi behind, and stick together. And do not leave enemies either, because Avi won't move if enemies are nearby.

Once you reach the middle, you can make a run for the elevator. You don't need to worry about Avi anymore, he will follow you outside.

When you get outside, quickly go to the middle, take cover by the 'Los Santos Government Facility' stone, and take out the chopper. This can easily be done by shooting the pilot.

Be very careful and keep an eye out for enemies that may ambush you from behind. Always look out for them on your minimap.

Keep clearing the enemies by the vehicles and enter the armored riot van when you see an opening.

Drive towards the exit. The door will be locked, but you can open it by shooting the fuse (marked with a red arrow).

You don't have to worry about getting shot at too much since you will be inside a riot van. It has good protection.

When you get outside, drive to the Avenger for the last part of the mission.

Now, you must use the Avenger turrets to protect the Avenger from incoming Merryweather choppers and jets. Keep protecting until the Avenger flies away to complete the mission.

With Avi Schwartzman rescued, the stage is set for the final confrontation in Shock & Awe.
