Sortie

Sorties are a set of three special missions that are assigned to players on a daily basis. Each Sortie consists of three missions of escalating difficulty that must be completed in sequence; preceding missions must be completed before proceeding to the next one. The individual missions in a Sortie each have their own unique hazards and conditions that make the mission more difficult, from loadout limitations to enemies with enhanced offensive or defensive abilities.

Regardless of individual mission conditions, only level 30 Warframes and players that have completed The War Within can participate in Sortie missions. If players are at max Riven Mods capacity, they will be locked out of Sorties and will be prompted to delete a Riven Mod or buy more Riven Mod capacity (if capacity isn't at 90) before they are able to do Sorties. Sorties reset, depending on Digital Extremes' local time, each day at 17:00 UTC or at 16:00 UTC during their DST. Each Sortie may only reward from its reward pool once a day. A player may still host, vote for, or help out with any part of a Sortie as many times as they wish, but forgoing any end-of-mission credits (keeping dropped credits) or additional Sortie rewards.

Completing all missions in a Sortie will grant the player with a random reward picked from the rewards pool containing 11 different types of items.

Each daily set of Sorties is thematically linked to a preexisting Boss, which will determine the Faction that will be present in all three missions.

Sortie Conditions

The following are the various Conditions that can be encountered in Sortie missions:

Condition	Effect	Notes
Augmented Enemy Shields	Enemies have vastly improved shields.	This condition is exclusive to the Corpus only.
Augmented Enemy Armor	Enemies have improved armor.	Corrosive Projection's effects are halved. Infested enemies who do not normally have armor will gain additional Ferrite Armor. The Corpus are excluded from this condition altogether. With the Corrupted, this modifier will only apply to Grineer units.
Cryogenic Leakage	Maximum Warframe Shield capacity is halved.	Patches of ice will be present throughout the environment, causing a constant 1 second proc to any Tenno contacting it.
Dense Fog	Limited visibility.	The environment will be shrouded in dense fog, limiting visibility. Can only occur on the Grineer Forest tileset and will always take place during the night.
Electromagnetic Anomalies	Gravity is reduced and clouds will dot the map.	Blue bubbles will be present throughout the mission, drawing nearby players in and inflicting a  proc to anything inside it. Gravity is reduced, affecting all airborne Maneuvers.
Enemy Physical Enhancement	Enemies will deal additional physical damage and have increased resistance to physical damage.	Additional physical damage granted to enemies can be one of the following: Damage will not be resisted (e.g.  Blade Storm).
Enemy Elemental Enhancement	Enemies will deal additional elemental damage and have increased resistance to elemental damage.	Additional elemental damage granted to enemies can be one of the following: Damage will not be resisted (e.g. Amps).
Energy Reduction	Maximum Warframe Energy capacity is quartered, and energy regeneration speed is significantly reduced.	The effectiveness of  Energy Siphon and Zenurik's Energizing Dash ability are greatly reduced. Flat energy gains (energy orbs,  Energy Vampire) are not reduced.
Eximus Stronghold	Eximus units spawn much more often.
Extreme Cold	Mobility is significantly impaired.	Sprinting is disabled for this mode. The speed of Maneuvers, casting, and reloading is reduced.
Fire	Maximum Warframe Health amount is halved, and recovery rate is significantly reduced.	A fire hazard, identical to the Meltdown in Reactor Sabotage, will slowly spread throughout the environment. Can only occur on the Corpus Ship or Grineer Galleon tilesets and will not occur if the mission type is Defense.
Low Gravity	Gravity is significantly reduced.
Radiation Hazard	Any physical damage received will also impart effects.	The environment will be tinted in a pale green light for ambience. Green clouds will be present around the level dealing high amounts of damage to units inside them. The damage done has a significant chance to cause a Proc. These clouds will not spawn if the selected mission uses the Grineer Sealab tileset.
Assault Rifle Only	Only Assault Rifles can be used and carried.	Despite its name, Primary Launchers can also be used. An Archweapon Deployer cannot be used.
Melee Only	Only Melee weapons can be used and carried.	This modifier cannot occur with Assassination missions. An Archweapon Deployer cannot be used.
Secondary Only	Only Secondary weapons can be used and carried.	An Archweapon Deployer cannot be used.
Shotgun Only	Only Primary Shotguns can be used and carried.	An Archweapon Deployer cannot be used.
Sniper Only	Only Sniper Rifles can be used and carried.	An Archweapon Deployer cannot be used.
Bow Only	Only Primary Bows can be used and carried.	Attica,  Nagantaka, and  Zhuge may also be used, but not the  Ballistica and its variants. An Archweapon Deployer cannot be used.

Mission Conditions

Apart from the above mission modifiers, the mission types in Sorties will also have their own specific conditions:

• Cipher usage is disabled, requiring all consoles to be hacked manually. Grineer consoles will only allow up to 3 mistakes to be made before the hacking fails and shocks the user.
• Rescue sorties will have the execution timer activate as soon as players enter the prison complex.
  • The amount of time to rescue the hostage is reduced.
  • Additionally, all enemies will prioritize attacking the hostage over the players once freed.
• Spy sorties require all three Data Vaults to be successfully completed.
  • The amount of time to retrieve the data if an alarm has been triggered is reduced.
  • Any console that must be hacked en route to the Data Vault terminal itself will simply electrocute players without setting off the alarm.
• Defense sorties require 10 waves to complete.
  • Missions will have players defending a mobile Tenno Operative instead of a stationary Cryopod. The Operative will wander about the environment, and can be revived if their health runs out. A player can also lend their secondary weapon to the Operative, similar to Rescue.
• Interception sorties require 2 waves to complete.
• Excavation sorties require at least 500 Cryotic before players are allowed to extract.
  • Resource Boosters cannot speed up the process, as the mission progresses by base amount.
  • Destroyed excavators will still produce some Cryotic, adding to the total Cryotic collected for the mission. Thus, it is possible to complete the mission even if players fail to protect the excavators provided enough is collected for the mission's objective.
• Survival sorties require a minimum of 10 minutes to complete.
• Exterminate and Sabotage missions will start with the enemies already alerted.
• Defection missions require 5 squads of Defectors before extraction opens, while allowing 6 Defector deaths before mission failure.
  • Enemy faction type will change to Infested for the duration of the mission.
  • If fire occurs as a mission condition, fire patches will be present on the ground, but fire damage will not spread throughout the map.
  • Once extraction opens, players have 5 minutes to extract otherwise the mission will fail.
• Hijack objectives will project a nullification field around it, preventing the use of Abilities near it.
• Assassination missions, if rolled, will always occur on the third stage. This will spawn their respective bosses at level 100. In addition, certain bosses may have slight alterations to their patterns.
  • Special access methods will not be required, even if applicable to the boss (e.g. Lephantis will not require an Orokin Derelict Key to access, nor will Ambulas and Kela De Thaym require their respective tokens).
  • Assassination targets will not drop their unique Warframe or weapon blueprints upon mission completion. (Ex. General Sargas Ruk will not give  Ember components, but can still drop  Split Chamber and an Orokin Cell on death). The two exceptions to this are Captain Vor (who can drop a  Cronus blueprint) and Kela De Thaym (who can drop a  Twin Kohmak blueprint).
  • Completing an Assassination will not count towards related Junction requirements (e.g. Killing Tyl Regor within the Sortie will not fulfill the Neptune Junction task until he is killed outside of the Sortie).
• Plains of Eidolon features three Incursion objectives. The mission ends as soon as the final objective is completed, with no need to run back to the Cetus gates to extract.
  • All players in the group will receive the same objective, despite being marked as "Free Roam."
  • If the Ghoul Purge event is active, the sortie may include Ghoul related incursion objectives.
• Capture, Infested Salvage, and Archwing missions will not be selected for sorties at all.

Rewards

Completing a mission for the first time will reward players with 20,000 Credits 20,000, 30,000 Credits 30,000, or 50,000 Credits 50,000 depending on which of the three Sortie stages was finished. These values are affected by Credit Boosters and Daily First Win Bonus. However, boosters earned from the final Sortie stage will not apply to the mission it was earned from (e.g. player is awarded a Credit Booster on completion; they will only receive 50K, not 100K).

Those who complete the full sequence of missions will receive a random reward from a limited pool of rewards. The rewards will differ between individual squads, but each player within a squad will receive the same rewards.

All drop rates data is obtained from DE's official drop tables. See Mission Rewards#Standard Missions for definitions on reward table rotations. Drop chances are rounded to two decimal places, following the official drop tables repository.
Expected means a player can expect to obtain at least one of a drop every N attempts on average.
Nearly Guaranteed refers to the total number of attempts a player needs to obtain a 1 in 10^2,3, and 4 probability not to have recieved a single drop (99%, 99.9%, and 99.99% probability to have received at least one drop).
The combined probability of multiple drops is 1 - ((1-A%) * (1-B%) * ...) (add drops in same rotation)

Tips

• It is recommended to coordinate with your teammates on what gear and loadouts to use.
• Stealth is recommended especially for objective-based missions like Spy and Rescue missions due to the strength of the enemy at the levels sorties take place. Alternatively, it may be prudent to simply ignore enemies altogether and prioritize heading to the objectives as quickly as possible.
• The bubbles in Electromagnetic Anomalies can be temporarily removed by , or damage, but will regenerate after 12 seconds. Detonating one will cause an proc to nearby units similar to destroying an Arc Trap. Wait a second before running through a freshly-detonated bubble, as it will proc anyone running through its dissipating core.
  • Using the Operator's Void Mode or Void Dash will completely negate this effect.
• Enemy status procs can be debilitating at the levels Sorties take place at, therefore  Rapid Resilience or  Quick Thinking can combat against strong damage-over-time effects such as or .
• The Fire Hazard condition will eventually spread to every room in the mission. Despite the lack of a timer, it would be wise to minimize backtracking and quickly devise an efficient route. Alternatively, equipping  Flame Repellent or Rapid Resilience can offer some damage mitigation if heavy fire contact is inevitable.
•  Covert Lethality can be useful in soloing sorties, as the mod's bonuses on stealth finishers can bypass armor scaling due to the enemies' high levels, on top ignoring any potential modifiers that increase enemy durability. Bear in mind that not all enemies can be killed with stealth finishers, so avoid them if possible.
  • For Sabotage and Exterminate sortie missions, where enemies spawn at the start of the mission in an alert state, enemies can be returned to relaxed status by initiating open combat to make them trigger a map-wide alarm or a lockdown, and then deactivating said states by hacking a control console. Alternatively, using abilities that trigger finisher attacks, such as  Paralysis,  Teleport, or  Cloud Walker, or abilities that induce sleep like Sleep Arrow and  Rest & Rage can be used to trigger Covert Lethality's fatal attacks even against alerted enemies.
• Playing solo will not decrease the mission difficulty, but can lower the amount of enemies spawned depending on mission type. Solo Interception players will capture points much faster than with a full squad, while fighting far fewer enemies. However it is still recommended to play with a full squad when tackling missions that require kills (Survival), or when fewer players will not lower enemy count (Exterminate).
• For Defense missions, bringing a  Limbo to  Banish the Operative or an  Ash to hide the Operative using  Smoke Shadow, can simplify the mission by helping the Operative survive the onslaught.
  • Additionally, removing the weapon of the Operative tends to make them stand still, rather than slowly wander around the map on-the-ready. This can be done with or without having a secondary equipped.
  • Giving the Operative a  Sonicor can help keep the enemies away from him/her.
  • Specters will automatically revive the Operative when they are bleeding out.
  • An armed Operative can be very powerful with a fully modded weapon, as the weapon's damage scales with their high level. In particular, a  Hikou or  Hikou Prime modded with high fire rate ( Gunslinger,  Anemic Agility, and  Lethal Torrent), multishot ( Barrel Diffusion and Lethal Torrent), and  Concealed Explosives will allow the Operative to one-hit kill anything up to level 80-100 armored Grineer (whose armor can be nullified by  Corrosive Projection).
• For missions that have weapon limitations, it is recommended to bring along a Warframe with high-damage offensive abilities, such as  Ember,  Excalibur, or  Nidus, to maintain effective firepower. Likewise, it would be helpful to utilize Warframes with damage-buffing abilities such as  Equinox or  Rhino.
  • On a related note, Exalted Weapons are unaffected by weapon-limiting modifiers.
• If planning to enter missions with enemy elemental resistance, consider modding weapons with physical damage mods (ex.  Heavy Trauma) and faction damage mods (ex.  Smite Infested) in lieu of elemental damage mods in order to maximize damage potential, and using Warframes whose abilities deal physical or non-standard damage types (e.g.  Excalibur,  Ash, etc.).
• Death Squads cannot appear during Sorties; however one may acquire a Stalker Death Mark by completing a Sortie Assassination.
• As Ciphers are unavailable for use in Sorties, the Liset's Override from Air Support Charges can be helpful in Spy and Rescue Sorties; it can help compensate for any mistakes made when hacking data vaults in Spy, and it can extend the time to rescue the hostage in Rescue.
  •  Intruder is also useful in easing the difficulty of Hacking in sorties as well.
•  Hildryn works best for the Energy Reduction modifier due to not relying on energy for her abilities.

Trivia

• Sorties were implemented in Update 18.0 (2015-12-03) on December 3rd, 2015.
  • At release, Sortie reward tables were divided into "seasons" that changed every few updates, with rotating Sortie rewards. This feature lasted until Update 19.0 (2016-11-11) retired the season mechanic altogether in favor of a fixed reward table.
  • During this period, among the rewards players could obtain included parts for certain Vandal or Wraith weapons,  Nezha components, Focus Lenses, the Pyra Syandana, and 3 Nitain Extracts.
  • During the Divine Will Tactical Alert (which happened from February 11, 2016 to February 16, 2016), Sorties rewarded an additional 25 R5  Fusion Cores.
• The Electromagnetic Anomalies modifier first appeared during Sortie Season 8.

Bugs

• It may be necessary to relog or finish any mission (visit a Dojo) to refresh the Sortie tab of the World State Window upon the Sortie reset time arriving, otherwise the game may simply display "No Sorties are available".
• Occasionally, there is a bug that will allow players to extract after 100 Cryotic on Excavation Sorties. This is most likely due to the fact that the original amount required was 100 before adjusting.
• There is an occasional bug where the Hijack Core / Rover will not have a nullification field around it.
