Alvaro’s Stash Key, or the key that opens Alvaro’s Gun Case, is an item you’ll need to retrieve as part of a Far Cry 6 Treasure Hunt named The Mongoose and the Man. It is one of the 21 Far Cry 6 Treasure Hunts available in the video game developed by Ubisoft and by far the funniest.

The Mongoose and the Man can be played upon reaching Madrugada, provided you know where to look for it. As you’ll see in the guide below, it involves a crazy mongoose named La Comadreja. So, below, we’ll go over this Treasure Hunt, and I’ll tell you everything you need to know about it, including how to open Alvaro’s Stash or where to find Alvaro’s Gun Case Key.

The first thing you’ll need to know is where to find this Treasure Hunt or how to start The Mongoose And The Man mission. As you can see on the map below, the starting location is in the small city named Siniestra. Siniestra is found on the western side of Costa Del Mar in Madrugada Province.

After you reach Siniestra, your next goal is to find the mission’s starting point, which is a note inside a red box. You can see it below, and behind it, you can also see a boat.

Read the note, and you’ll find out that the house you are going to explore belongs to Alvaro, who was tortured by La Comadreja. Just so you know, La Comadreja means Weasel, even though Alvaro’s problem involves a Mongoose, which is far more dangerous than a Weasel. And as you’re about to find out, it is ten times faster.

Where To Find Alvaro’s Stash

After you read the note, your next goal is to find Alvaro’s Stash. And to do so, you’ll need to enter his yard, so start by shooting the locker on the gate. Don’t worry because he is not home. Once inside the yard, enter the house and start looking around.

There are several materials you can loot from this place, as well as a Hidden Story Collectible (Art Scraps I), which is part of the Art & Death Set. You’ll find it on the table. What is more important, though, is Alvaro’s Stash or Chest, which you can see below. Notice that it’s by the window.
