El Sin Nombre is the eleventh mission in the game and it takes place in Las Almas, Mexico. Players will be assuming the role of Soap as they are guided by Alejandro Vargas from the Mexican Special Forces.

The mission starts with Soap pretending to be a snitch and heading to the Las Almas VIP meeting to spill information about the team that attacked the cartel. As Soap approaches the compound, he will be masked by the guards and taken to meet El Sin Nombre. Alejandro will reveal that he assumed the role of a guard for this operation as Soap is being transported by the elevator.

Right after the elevator stops, players will be introduced to Diego. Follow him to meet Valeria, who will already be interrogating a few Mexican military personnel. She will ask you to take a seat and then begin questioning you.

Here are the correct answers to all her questions:

  • Q: Who attacked us?

A: It was Mexican Special Forces.

  • Q: Who were they?

A: American PMCs. Shadow Company

  • Q: Who leads Shadow Company?

A: Philip Graves

  • Q: What does he want?

A: Missiles

After the interrogation is complete, follow Diego and Valeria into the elevator and reach Alejandro. He will hand you a knife and mask for self-defense in the cartel-infested compound.

Post this scene, you will be offered two choices: Take Diego's keycard from the second-floor ofrenda or find a way to the roof.

You are now free to move around the campus and decide how you wish to approach the situation but under the guise of stealth. The second floor and garage are off-limits and guards will fire on sight.

You can pick up bottles and a throwing knife from the bar to distract enemies and take them out if things go wrong.

Now proceed south of the compound and turn left at the end. You will find a small wall allowing you to get up on the balcony. Climb up and get inside. Now head left and the stairs will take you to the second floor. There will be more throwing knives here, one to your left on the table and one straight ahead on the counter along with some bottles.

You will now see armed personnel on the balcony guarding the door with Diego inside. Use your throwing knives to take him out. Now proceed to open the door. Do not bash in as this will alert the guards. When you open, wait for a few seconds before heading in.

When both Diego and the guard look the other way, use a throwing knife to take out the first guard. He will drop his phone and it will start ringing. Proceed to immediately turn it off. Then sneak up on Diego to eliminate him as well. You will find the keycard there on the ofrenda along with the option to pick up a golden .50 GS and a Lockwood 300.

As you head out, Alejandro will alert you about the guards approaching your position. Do not engage at this point and find a place to hide. There will be a closet on your right (left if you are headed out) with armor plates. Get inside and remain there till the guards leave.

If you want to find a silent weapon at this point, look for a small cabinet near the entrance to the room where you killed Diego. Once opened, you will find a silenced P890 pistol inside but only with 10 bullets.

When you are ready to leave, simply head to the small room directly to the left of the exit. Escape through the open window and reach Alejandro and enter the elevator.

Follow Alejandro through the corridor and as you reach outside El Sin Nombre's room, use the camera to get your eyes on the cartel's leader.

It turns out Valeria was the Sin Nombre all along.

After a brief conversation with Alejandro, you will swing open the doors and eliminate all the guards inside. Rush outside to find that your squad mates have already surrounded Valeria, and she has no path to escape. Proceed to capture her.
