Your friendly guide to completing the El Sin Nombre mission in Call of Duty: Modern Warfare II without raising alarms. Learn how to sneak past guards and reach the penthouse undetected.

Alright, so you've just finished up Valeria's interrogation in the El Sin Nombre mission. Alejandro's waiting for you on the ground floor. Here’s how to get to that penthouse without anyone knowing you were even there.

Walkthrough
  1. 1
    First things first, head into the bar right across from where you start. You’ll need to grab two bottles from inside. These are your best friends for distracting guards.
  2. 2
    Now, move deeper into the building. You’ll find a spiral staircase with a guard posted at the bottom. Don't worry about him; just approach him, and he'll move away.
  3. 3
    Quickly head up the stairs to the second floor. There’s another guard chilling near the balcony. This is where those bottles come in handy. Press [ / ] to throw a bottle into the distance in front of him. He’ll go check it out, giving you a window to act.
  4. 4
    Hop over the balcony and sneak to the left. You’ll find a ladder – climb it.
  5. 5
    You’re getting close! Now you’ve got three more guards to deal with before the penthouse. Crouch down and stick to the right side of the area. Use those bottles again to distract any guards nearby by throwing them into the distance.
  6. 6
    Once they’re distracted, climb the ladder on the opposite side. This will bring you back up to Alejandro.
  7. 7
    Jump into the elevator shaft and use the buttons to descend. Keep an eye out for when the third-floor door is clear of enemies.
  8. 8
    Once it's clear, interact with the emergency lock to open the door. Head to the end of the corridor to unlock the 'Ghost-in-Training' Trophy/Achievement!
Tips
  • Make sure you grab those two bottles early on. They are crucial for this stealth approach.
  • Crouching and sticking to the right side of the area helps you stay out of sight.
  • Throwing bottles into the distance is key to luring guards away from their posts.
  • Be patient with the elevator shaft; wait for the third floor to be clear before exiting.

Completing this objective without killing anyone or triggering the alarm earns you the 'Ghost-in-Training' Trophy/Achievement.
