**Vaults** are a type of [[:mission]] which can occur in both [[:modes:#Campaign modes]] and [[:modes:#Endless modes]]. The primary objective of a Vault mission is to loot the [[#Deposit Boxes]] for [[:credits]], and loot the [[:mainframe devices:Secure Cases]] for [[#Research Experiments]].

The Vault room is protected either by an [[:mainframe devices:Emitter]] connected to a [[:mainframe devices:Power Supply]] also in the Vault room, or a [[:guards:Captain]] and two [[:mainframe devices:Sound Bugs]]. Some of the loot in a Vault is locked behind a [[:doors#Vault Door]], requiring a [[:items:Vault Access Card]] to access, but it is not necessary to have a Vault Access Card to get the rest of the loot.

There are three [[:prefab]] Vault layouts:

^ Prefab layout ^ Security measures ^ Outer vault ^ Inner vault (requires keycard) ^
| [[:prefabs:Vault 1]] | [[:mainframe devices:Emitter]] | Vault Terminal \\ 4 chests of Deposit Boxes | 2 chests of Deposit Boxes \\ Secure Case |
| [[:prefabs:Vault 2]] | [[:mainframe devices:Emitter]] | 2 Secure Cases | Vault Terminal \\ 4 chests of Deposit Boxes |
| [[:prefabs:Vault 3]] | [[:guards:Captain]] \\ 2 [[:mainframe devices:Sound Bugs]] | Vault Terminal \\ 4 chests of Deposit Boxes \\  | 2 Secure Cases |

The Vault mission objective is optional; if you find the [[:facility#exit room]] and try to leave before looting the vault, you will be warned by a dialog box, but this only asks you to confirm that you want to leave.

===== Vault Terminal =====
[{{ :mainframe devices:vault_terminal.png?100|A Vault Terminal.}}]

> //There's the vault terminal. You'll need to hack that to release the secondary locks.// \\ ---[[:agents:Central]]

The **Vault Terminal** is a [[:mainframe device]] found in the Vault room. If hacked and accessed by an [[:agent]] on an adjacent tile, it unlocks the [[#Deposit Boxes]], allowing them to be looted. However, hacking the Vault Terminal also triggers the corporation's [[#security response]].

The Vault Terminal provides [[:cover#soft cover]], allowing agents to hide on adjacent tiles. The Vault Terminal cannot be accessed while it is [[:rebooting]], or by an agency-controlled [[:drone]].

===== Deposit Boxes =====
[{{ :mainframe devices:deposit_boxes.png?100|A chest of Deposit Boxes.}}]

**Deposit Boxes** are found in Vaults, and can be looted for [[:credits]] after first being unlocked using the [[#Vault Terminal]]. Each chest of Deposit Boxes contains 200--275 [[:credits]]; the amount is random.

Deposit Boxes provide [[:cover#soft cover]], allowing agents to hide on adjacent tiles. Deposit Boxes are not [[:mainframe devices:]], as they do not have [[:firewalls]] that can be hacked, but they can be [[:rebooting|rebooted]] by [[:items:EMP Packs]]. Unlike [[:mainframe devices:Corporate Safes]] and other lootable devices, Deposit Boxes cannot be looted while they are rebooting, unless they have already been unlocked using the Vault Terminal.

Vault rooms can contain some decor objects which are visually similar to chests of Deposit Boxes; they are purely decorative and should not be confused for Deposit Boxes.

===== Research Experiments ======
[{{ :items:valuable_tech.png|Research Experiment icon}}]

> //An ongoing science project. The black market will pay well for its secrets. Bring it with you when you exit the level.//

**Research Experiments** are [[:items:]] which can be looted from [[:mainframe devices:Secure Cases]] in the Vault room. There is a reward of 500 [[:credits]] for each Research Experiment carried out of the mission; to receive the reward, it must be carried by an [[:agent]], not left on the floor in the exit teleporter. Research Experiments have no other use, and cannot be sold at a [[:mainframe devices:Nanofabricator]] during a mission.

Each Secure Case in a Vault contains one Research Experiment. When one of the Secure Cases is hacked, the corporation's [[#security response]] is triggered.

===== Security response =====
> //You've got the goods, now don't dally. They're sending someone to investigate the security breach.// \\ ---[[:agents:Central]]

In response to the agency hacking either the Vault Terminal or a Secure Case, the corporation //usually// brings in reinforcements --- an [[:guards:Enforcer]] spawns at a random [[:facility#guard entrances|guard entrance]], and is [[:guard behaviour#interest point|sent towards]] the hacked device. The security response happens at most once in the mission; once it has been triggered, hacking more devices does not bring more Enforcers.

The response is not //always// triggered by hacking one of these devices. Specifically, the Enforcer spawns when you hack the Vault Terminal or a Secure Case using a [[:programs:breaker]] program which targets a specific device, breaks its [[:firewalls]] immediately, and breaks the exact number of firewalls the device has when the program is used. This means the Enforcer does not spawn if you:

  * Use an [[:items:EMP Pack]], [[:agents:Dr. Xu]]'s [[:augments:Subdermal Tools]], or the program [[:programs:Fool]] to disable the Secure Cases.
  * Hack using [[:items:Buster Chips]] or the [[:items:Prototype Chip]].
  * Hack using a program which breaks more firewalls than the devices have when the program is used.
  * Hack using [[:programs:Data Blast]], which does not target //one specific// device, even if only one device is in its area of effect.
  * Hack using [[:programs:Parasite]] or [[:programs:Parasite 2.0]], which do not //immediately// break firewalls.

The security response is never triggered by hacking the [[:mainframe devices:Power Supply]] or [[:mainframe devices:Sound Bugs]] protecting the Vault room.
