Marchenko's Kill Switch

Marchenko's Kill Switch or Damocles' Sword is a unique weapon in Deus Ex: Mankind Divided. Controlling the bomb in Victor Marchenko's head, it can be used to remotely kill him.

Location
There are two places where the Kill Switch can be found, and it is well hidden in both areas. The first is in Hangar 2 in G.A.R.M., where it is in a locker behind a hidden panel. To get it, use a button on the back side of the lockers. The second location is in London, in a room near where Miller is found. Under the desk and behind the studio bags, it is in a weapons briefcase. Despite there being two locations to find it, there is only one Kill Switch, so if Jensen takes is in G.A.R.M., it will not appear in London.

Intended Purpose
The Kill Switch was voluntarily installed by Marchenko. He gave the Kill Switch to the Shadow Operatives he is working with and told them to activate it if he goes off mission.

Gameplay Function
The Kill Switch has no function until Jensen meets Marchenko in the exhibition hall. At that point, it can either be used during the cutscene to avoid the fight altogether, or during the fight for the same fatal effect. Using the Kill Switch during the cutscene can be used to delay Marchenko detonating the bombs if Jensen saved Brown and did not reach Marchenko in time.
