The Clockwork Soldiers are some of the most intimidating and frankly, the most creepy enemies that are present within Dishonored 2. They also require a little bit of skill and a fair bit of luck to take down, which is why it is a good thing they are so complicated to create, otherwise they would be everywhere.
The Clockworks are able to see in front of them as well as behind, quite literally having eyes in the back of their bodies. So the only viable ways to take them out is to either approach them from the side or from above. Be sure to be quiet though because they will pursue you relentlessly if they do detect you.
The Stun Mines are a useful tool to stop the Clockwork’s in their tracks. When a Stun Mine is triggered by one of these mechanical monsters, they will be powered down for about three seconds. During this time you can either retreat to a safe distance or you can go crazy with your sword and hack and slash your way to victory.
One of the most lethal types of weapon in Dishonored, the Springrazor is quite capable of tearing apart the metal casing of the Clockwork Soldiers. It takes two Springrazors to fully eliminate a Clockwork. The first will tear off the metal plating, exposing the vital parts of the mech, and in some cases it can remove the Clockwork’s head (depending where you place the Springrazor). The second mine triggered by the Clockwork will cause it to blow up, allowing you to go on your way.
Normally the most lethal form of assassination in the game, the drop assassination will not be sufficient to take down a Clockwork Soldier, only removing the head of the enemy, which will render it unable to see. It will stand still and react to any loud sounds. In order to take it down entirely, you will then need to do another drop assassination if you wish to remain out of harms way.
Go Cray Cray In A Big Way
This is exactly what it sounds like, hacking and slashing like an insane person until either you or the Clockwork is reduced to nothing but scrap. From the back of the soldier you are able to remove the back casing with one or two swings, the front being a bit more resistant to attack. Once the casing is gone, you can either destroy the tank of whaleoil that is held there to stop the Clockwork, you could rewire it if you are stealthy enough or you can even procedurally remove its limbs, rendering it harmless.
