The Killhouse

Summary
The Killhouse is the training ground for Halcyon operatives. In this training session, you must breach a vault and steal the target, which appears to be a gold bag (AND Mystery Mask on April 16th Operative+).

Things to Know Before Starting the Mission

 * 1) All bullet cameras are loopable.
 * 2) Disabling the sensors is easy, there are 3 options.
 * 3) Easy to get disguises without being spotted.
 * 4) No civilians on site.
 * 5) No check-in protocols like The Financier, meaning you can knock/kill everybody and no one will notice.
 * 6) You are forced to use the drill if you knock out the vault guard before interrogating them.
 * 7) There's very little cover around the map, making it difficult to hide a body far away from the spawn room.
 * 8) You will be out in the open virtually everywhere, suspicious activities can be hard to pull off.

Tools

 * Lockpicks
 * Optional: Key card scrambler (in case you don't get a key card quickly)
 * Optional: Suppressed UP9 (there are already some provided for you)
 * Optional: Breaching charges (if you can't hack, but they are also provided)
 * Optional: Microcams and trackers. Two other sets of eyes. 3 is you hack cameras

Process
There are two methods for completing this mission.

Method 1: The Quiet Way

 * 1) Lock pick the door in your way. Or just shoot it.
 * 2) Optional: Get a disguise.
 * 3) How to do it:
 * 4) Find a guard (interrogate them if you can) and knock them out.
 * 5) Take their disguise.
 * 6) Hide the body.
 * 7) Why do it: Disguises are practically required for any successful stealth mission.
 * 8) Optional: Take out the camera guard. (Not possible on Legend)
 * 9) How to do it:
 * 10) Bypass the door by scrambling the key card reader or finding a key card, and using it.
 * 11) Knock them out.
 * 12) Why do it: Cameras are a devastating tool for guards, missions become far easier without another set of eyes to watch you.
 * 13) Disable the sensors using one of the methods:
 * 14) Disable the correct fuse box.
 * 15) Identify which fuse box to disable. You can do so by finding the vault and identifying the color of the wire on the sensor.
 * 16) Find the correct fuse box and disable it.
 * 17) Hack the laptop and wait 20 seconds. Requires the Prodigy perk.
 * 18) Disable the sensors right at the vault. Requires the Demolitions Expert perk.
 * 19) Interrogate guards to find the code. Only one of them has it.
 * 20) Open the vault and grab the bag.
 * 21) Run back to your starting point, don't get caught.

Method 2: The Direct Way

 * 1) See "Stealth Process, Method 1" steps 1 - 4
 * 2) Take out all of the guards.
 * 3) Take the diamond drill and start drilling the vault. Wait for it.
 * 4) Grab the objective once the vault is open. Get back to the spawn point.

Tools:

 * Optional: A good weapon (there are already some weapons provided)
 * Optional: Another weapon (if you happen to run out of ammo, UP9s are provided)
 * Optional: Med packs (there are already some scattered around the map)
 * Optional: Grenades (to make a long battle short)
 * Optional: Aegis armor (only use if you have the Demolitions Expert perk, the speed loss is devastating)
 * Optional: Any way to get through doors (everything you need is provided already)

Process:

 * 1) Grab everything you need, if you haven't equipped it in your loadout, but leave your equipment bag behind. Equip the following:
 * 2) Something to get through doors
 * 3) A weapon
 * 4) The diamond drill
 * 5) Optional: Grab med packs from all around the map. This can be helpful to keep you alive.
 * 6) See "Stealth Process, Method 2" step 3 - 4

Tips

 * Almost everything is provided for you in the Killhouse. Save some money and don't bring anything provided already.
 * Shooting wooden doors opens them.
 * Keycard scramblers are useful if things go loud, you can use it to hack keycard doors.
 * Hack the security cameras if you can, they help the mission by giving access to you for spying the guards without the danger of being spotted.
 * Don't bring Aegis if you want armour during a stealth mission, you can't disguise or remove it.
