Best Way To Reach The Penthouse Without Alerting Anyone¶

Once you’ve successfully completed Valeria’s interrogation during the beginning portion of the El Sin Nombre mission you’ll meet up Alejandro on the ground floor. Here you’ll want to enter the bar which is directly opposite your starting location and grab two bottles which you can use to distract guards, then head further into the building and you’ll stumble across a spiral staircase which has guard at the bottom.

Approach him and he’ll leave the room, so quickly make your way up to the second floor and you’ll find another guard standing near the balcony. Here you’ll want to make use of those bottles, so press / and throw it into the distance in-front of him and wait for him to investigate it. You’l nowl want to hop over the balcony and sneak around to the left to find a ladder that you’ll want to climb up.

(1 of 6) Grab two bottle

Here you’ll now need to deal with three more guards before you can approach the penthouse, so crouch and hug the right side of the area and throw bottles into the distance to distract any nearby guards, then climb up the ladder on the opposite side to join back up with Alejandro. Hop into the elevator shaft and use the buttons to go down until the third floor door is clear, then interact with the emergency lock to open the door, then go to the end of the corridor to unlock the Trophy/Achievement!
