The Piercing Gaze Hunter mask is a secret item you can unearth in The Division 2, but you’ll need to gain access to the Echoes of Central Park DLC. Then, you’ll have to solve a set of clues and recover few letters to get your hands on this mask.
Let’s find out how to get this secret gear added to your in-game collection.
How to obtain the Piercing Gaze Hunter Mask in The Division 2

First, you have to head to the location shown on the image below. Go to Lincoln Square district, and the spot will have a wall covered in leaves. It’s not difficult to find, and you’ll notice a bunch of text saying “Break my Walls”.

Shoot the wall, and you’ll find letters on it. Keep shooting until all the letters are visible. This is the first location where you find the letters. However, there’s a second location where you’ll find more of these letters.

Head to the marked spot on the image above, and you’ll find a second wall with the text “Break my Walls” written on it. Again, start shooting until you get three different letters.

Once the parts mentioned above have been solved, go to the southern part of the Lincoln Square District. You’ll find a roof with plant pots and statue, and you need to destroy all of them.
Some of these pots will be indestructible, and you need to keep shooting at them. This will eventually summon the Hunter.

To get your mask, you’ll have to defeat the Hunter as it’s the only way. As long as you stay clear from the Seeker Mines, you shouldn’t have any problem defeating the Hunter and obtaining the secret mask.
