Spy

Spy (ver 2.0) is a Mission type where players are tasked with extracting confidential data from enemy data servers.

Mechanics
Spy missions require players to locate consoles found in Data Vaults, which are special rooms featuring heavy security and advanced defense mechanisms guarding the console access terminals. Each mission will have three separate Data Vaults, of which all three must be breached and attempted before extraction becomes available. Players must breach the Data Vault rooms and then hack the access console in order to extract the data. If a Tenno trips over the Data Vault's security features, or an enemy activates the Data Vault's alarm, the Data Vault's defense mechanisms and enemy reinforcements become active, and a countdown timer will initiate indicating the time until the data is wiped off the server, giving players 20 to 50 seconds (depending on difficulty) in which to attempt to reach the console and hack it.

Similar to Rescue Prison Complexes, Data Vaults often feature alternate paths and tunnels that can be used to stealthily bypass the Data Vault's defenses, allowing for stealthy completion of a Data Vault.

End-of-mission rewards for Spy missions depends on the number of Data Vaults successfully hacked, with at least one vault hack needing to be successful in order to accomplish the mission.

Defenses
Apart from enemies patrolling the rooms, the Corpus and Grineer have different emplaced defenses set up around their Data Vaults, with the defenses present depending on the variant of Data Vault. The defenses present will initiate each vault's alarm if tripped. Some security measures can be disabled if nearby panels are hacked.

Corpus

 * Security Camera: Security Cameras in Data Vaults will trigger alarms if they spot the player. It is possible to instantly destroy them without triggering the alarm.
 * Laser Barriers: Tripping over laser barriers in Data Vaults triggers the alarms. Unlike the normal Laser Barriers, those found in Data Vaults have a variety of mechanisms to confuse players, such as laser barriers that move, and barriers that periodically deactivate. Invisible players will still activate the alarms, but players in the rift will not.

Grineer

 * Sensor Bar: Data Vault alarms can be triggered by passing through energy doors that deal proc. Some energy doors in a Data Vault may not have Sensor Bars attached to them, making them impossible to deactivate. Invisible players will still activate the alarms.
 * Motion Detector: Some Grineer vaults have defenses involving scanners that sweep a yellow energy curtain across the console, triggering the alarm if the curtain is touched. These scanners have to be deactivated using consoles within the Data Vault to ensure safe hacking.
 * Sensor Regulator: These mobile Regulator variants patrol Data Vaults, and will trigger alarms if they spot a player or take damage and survive.
 * Spark - A unique variant of the Bombard can appear as reinforcements if multiple Data Vault alarms have been tripped.

Some Data Vaults may also feature security doors and pit traps that will engage upon alarms being triggered, which can impede a player's movement through the vault.

Whether a player succeeds or fails in retrieving the data inside the Data Vault, the vault itself will become easier to exit from: Corpus Data Vaults will have their laser defenses and any pit traps deactivated, while Grineer Data Vaults can open alternate passages that lead to the exit.

Rewards
Spy missions can reward the following items upon successful completion, with the number of rewards dependent on the number of Data Vaults successfully hacked, with each hack providing one reward each for a total of three rewards, regardless of whether the hacks were completed stealthily or not.

Tips

 * If there is a general alarm as you traverse the level, wait until you arrive at a vault to disable it. Any previously alerted enemies won't reactivate the alarm unless they were already in the process of doing so.
 * When you enter a vault, the alertness levels of most enemies outside it will drop, and they will not follow you in (though they may patrol through the now unlocked doors.) It is advisable to wait a moment in the vault's antechamber in case you unknowingly encounter one of the exceptions. Exceptions include:
 * Drahk
 * Drahk Masters
 * Rollers
 * Latchers
 * Melee units (ex. Scorpions, Butchers, Prod Crewmen)
 * Timing in the vaults is based on when you begin to hack the door. If you take longer on your hack, enemies will have progressed along their patrol routes.
 * When enemies set off the alarms in the vault themselves, their trigger functioning is similar to that of a regular alarm, meaning if the map dedicated alarms haven't been activated in a while then they will have a good chance to raise the vault alarms.
 * Sentinels and Kubrows do not trigger Sensor Regulators or Laser Barriers, allowing free usage inside Data Vaults, however, can still trigger the alarms via attacking enemies
 * Spy 2.0 was added in Update 15.13.

Bugs

 * Spy missions sometimes fail even if no data is lost.
 * Occasionally hitting a barrier directly outside the vault will trip the alarm.
 * Occasionally, in the Grineer "conveyor belt" vault, the visual effect for the blast effect walls will not render. They still behave normally. Their location can be identified by the frame in place where it normally is, with a yellow tint to it. (as recent as Update 15.16)
