4	After talking to Alejandro, walk down the hall and enter the first room to your left.
5	Make your way to the kitchen. Pick up a few bottles from the counter to use as a distraction for the guard outside.

7	Once you're on top of the garage, make your way to the hall on the 2nd floor and enter the room on your left. Do be warned, sometimes a guard taking a smoke break waits here. If this is the case, wait for him to leave before heading into the room.
8	In that room, you can find a throwing knife on the table to your left. Take the throwing knife as it will allow you to perform stealth takedowns.
9	Walk out of the room and head to the room with the pool table. There will be guards patrolling the area so just keep crouching and wait for them to walk away.

Interrogation Answers

Question #1 - Mexican Special Forces

For the first question, Valeria will ask Soap who attacked them in the mountains (alluding to the Cartel Protection mission). There are three options during this sequence:

• It was Mexican Special Forces
• It was the Mexican Army
• It was Cartel

The correct answer will be the Mexican Special Forces option.

Question #2 - American PMCs. Shadow Company

For the first question, Valeria will ask Soap about the 'outsiders' that helped the Mexican Special Forces during the engagement. The following are the three options during this interaction:

• Your Competitors
• They work alone
• American PMCs. Shadow Company

For this question, the correct answer will be the American PMCs. Shadow Company option.

Question #3 - Philip Graves

For the third and final question, Valeria will ask about the leader of Shadow Company. The last question will also have three possible options:

• Philip Graves
• Alejandro Vargas
• Ghost

To proceed with the mission, answer Philip Graves.

Two Wrong Answers Will Compromise the Mission

Making a mistake during the interrogation will not lead to a mission fail right away. Instead, Valeria will ask a follow-up question to give the player another chance.

However, if Soap provides the wrong answer for a second consecutive time he will be shot and the mission will restart at the last checkpoint.

How to Beat El Sin Nombre in Realism Difficulty

Realism Difficulty Tips
Pick Up and Use Bottles to Distract the Guards Wait for the Balcony Guard to Leave Go for the Trellis and Climb the Roof Distract the Guards on the Roof Immediately Pre-Aim the Heavy Armor Soldier in the Penthouse

Pick Up and Use Bottles to Distract the Guards

There will be at least 2 instances where you have to distract guards using bottles. To get a few, head on over to the dining room where you can find 4 bottles. Use these to get the guard near the stairs to move, allowing you to sneak outside and onto the AC units undetected.

Wait for the Balcony Guard to Leave

The guard waiting on the balcony leading to the 2nd floor will take a quick smoke break. Stay crouched and hidden until he walks back inside the structure. Do not try to cross while he is outside since the balcony railing is not high enough to conceal you.

Go for the Trellis and Climb the Roof

With the guard out of sight, use the ladder on the trellis to climb up to the roof. This is the safest way to make it to El Sin Nombre while avoiding detection. Getting the keycard requires you to fight while heading to the Garage only equips you with weapons you can't use stealthily.

Distract the Guards on the Roof Immediately

Once you're on the roof, immediately chuck a bottle in front of the 3 guards to distract them. Move to the bar while they're distracted then, from there, head up the ladder to get to the elevator shaft.

Pre-Aim the Heavy Armor Soldier in the Penthouse

When you breach and clear El Sin Nombre's office there will be a total of 4 guards (including Diego) inside. Kill Diego and 2 others before pre-aiming the hallway to the right of the room. A heavily armored soldier will emerge from here so make sure to aim for his head and drop him quickly.

Note: There is a trigger error when shooting enemies inside the room before Valeria escapes. If you shoot the guard who helps Valeria and the one to the left of the room, their deaths will be delayed until Valeria is on the roof (they will look alive but then ragdoll after a second or two).

El Sin Nombre Achievements

Ghost-in-Training

	Ghost-in-Training
	Reach the penthouse in 'El Sin Nombre' without killing anyone or triggering the alarm.

While there are many ways of getting to the penthouse, Ghost suggests you use the trellis out by the garage and climb to the roof. It is best to take his suggestion as this is the easiest way of getting to the penthouse while getting the Ghost-in-Training.

Patience is key in getting this achievement as you will need to wait for the guards to walk past your path. You can find bottles placed around the area and we recommend picking them up as they can be used to distract the guards.
