Stamford Lockpick
Several times during the game you encounter locked security doors. You can’t just ram these open with a shoulder. The only way to get past reinforced doors is to use your handy Stamford Lockpick tool.
Here’s how:
- Approach the security door and press
. Galahad automatically inserts the lockpick in the keyhole. This gives you an x-ray view of the lock’s inner workings. - Hold in
to drive the air cylinder, which exposes the first of three tumbler pin positions. You can see the first pin as a ghostly white rod on a spring (circled in our shot). - Keep holding in then slowly rotate the right stick until the vibration in your controller slows down. (If you toggled Vibration off in your game’s option settings, watch onscreen for the tumbler pin to be pushed upward and turn brighter white.)
- When this happens, press
to engage the pin. It clicks upward, out of the lock housing. - Now you have two more tumbler pins to go. Repeat the same process with each of the remaining pins to unlock the door. Press again to turn the lock, which slides the metal lockbars out of their slots. Open the door and enter the next room.
TS-27 Inverter/Rectifier
In The Order: 1886, a few doors and hatches have powerful electromagnetic locks. The only way to disable such a lock is to disrupt its power supply. Fortunately, you have Nikola Tesla on your team. At the end of Chapter II, Nikola gives Galahad his latest invention, a TS-27 Inverter/Rectifier device that converts currents. As he explains, “Quite handy for overloading and incapacitating certain electrical systems.”
Later, when you encounter doors with electromagnetic locks, open the red circuit box on the door. Galahad automatically hooks up the TS-27’s brass clips and you get the TS-27 interface.
A small blob of mercury bounces up and down inside each of the two tubes on the device, and a pair of red needles is positioned over each tube. Your objective is to lock both mercury blobs between their respective pair of needles.
Click and hold the left control stick 
to lock down the mercury in the left tube. Click and hold the right stick V to lock down the mercury in the right tube. You must have both mercury blobs locked to activate the device. You don’t have to lock both simultaneously, but if you hold one for too long without getting the other, the device resets. When activated, the TS-27 blows the circuit to which it’s connected, disabling the lock.
