When the player has completed the first and second part of the level while avoiding her sniper rifle, the player will enter the Sniper Nest, a sniper section where the player uses a sniper rifle to take out Vall. There the player can see Vall and finally kill her in one shot.
Vall is the weakest enemy in the game only matched by Timur The Tinkerer and a Security Camera, she can only endure one shot and one punch. This doesn't really matter though, since you can only use the sniper rifle to get rid of her anyway.
- You can't kill Vall via punches through normal means, since she only appears in the sniper section of the mission Vall. However, you can spawn her in the level editor and kill her there; she dies to one punch because you were never supposed to punch her or shoot her with any gun other than the sniper rifle.
- If you kill all the enemies with a headshot in Vall's Sniper Nest, you will earn the achievement "Le Sniper du Cœur".
