Defection is an Endless Mission type introduced in Update 19.12 for the The Pacifism Defect event. This game mode tasks players with escorting small squads of Kavor Defectors to an extraction point, while defending against the Infested.

Originally introduced under the name "Evacuation", this mission type was renamed as part of Update 21.0, and is now the source for HarrowIcon272 Harrow's Systems component. All three Defection nodes are Dark Sectors.


Players start near a shuttle bay room, which the Kavor defectors must reach in order to escape the ship. The mission begins once a player hacks the door leading out of the shuttle bay.

Kavor defectors will spawn 30 seconds after the mission officially begins, and every 40 seconds after the previous group is rescued, though this countdown can be set to zero instantly if one player activates a rush panel indicated by an orange icon. These Kavor defectors will then head towards the nearest Med Boosters, a structure that will heal nearby Kavor defectors with a green beam. Med Boosters will consume power as they heal Kavor defectors, with more survivors resulting in faster energy drain. To keep the Med Boosters powered, players can acquire Power Cells dropped by Mutalist Osprey Carriers, which they can carry to a Med Booster to recharge its power by 20% (40% for solo play) per Power Cell. Players must issue a Move Out command on the Kavor defectors to make them proceed to the shuttle bay for extraction.

After two groups of survivors have been evacuated, the player's extraction point will be opened up, and the second Med Booster will spawn in a different location of the map (B). After two more groups have been evacuated, a third Med Booster will spawn along with opening up more of the map (C). From this point on, points B and C will begin hosting a group of Kavor defectors, with them both pathing to A's Med Booster, and then to their evac location.

Kavor defectors will slowly take damage over time from the Infested spores in the air. Downed Kavor defectors will enter bleedout, and will die unless revived by players. If 10 Kavor defectors are killed, the Lotus will abort all further evacuation efforts; no more Kavor defectors will spawn, any Kavor defectors still alive on the map will not count toward the player's totals if they reach the shuttle, and the players will have five minutes to extract.

Grineer Manics will spawn periodically upon the second Med Booster being opened, and will attempt to attack the Kavor defectors. Killing these Manics will make them drop Large Power Cells, identifiable by their white energy glow, which can instantly restore a Med Booster to 100%.

Every 7 squads rescued will cause enemy Red Veil Operatives or Fanatics to spawn. They are essentially the same units encountered during the Chains of Harrow Quest. They will primarily target the Kavor defectors during the mission and scale in level as the mission progresses (confirmation needed). This will occur regardless of player standing towards that Syndicate; killing them will not lower Standing towards them either.

  • TrinityIcon272 Trinity's Blessing130xDark Blessing affects defectors, essentially making her a mobile healing beacon and extremely useful in defection missions. A maximum efficiency and energy capacity build can make for a large breathing room in later stages of a defection run. It should be noted that while Blessing130xDark Blessing is active, casting it again will not heal or refresh the ability on affected defectors. So if one wishes to keep refilling the defector's health without much waiting, a low duration build can be an effective method.
    • Likewise, Trinity's WellOfLife130xDark Well Of Life can be used in to create a temporary healing beacon. Given the enemy density in infested tilesets, a resourceful Trinity can create healing beacons along the defectors' path.
  • LokiIcon272 Loki's SwitchTeleport130xDark Switch Teleport effects individual defectors and can be utilized to cover ground very quickly given a clear line of sight. Loki can also save defectors who are stuck in their path due to the environment. The augment Mod TT 20pxSafeguard Switch seems to protect from damage but not the health drain.
    • Loki's Decoy130xDark Decoy can be used to distract the infested from defectors provided it is within their vicinity. This can prove useful in a mid-tier scaled stretch of a defection run to provide a few seconds worth of relief should things go south.
    • Loki's RadialDisarm130xDark Radial Disarm Radiation b Radiation procs can create some breathing room if need be, though it is risky. Use with caution when surrounded by infested because they may still target the defectors if they are close enough.
  • NovaIcon272 Nova's WormHole130xDark Worm Hole can be used to speed up  travel time for groups of defectors but is tricky to use. In some cases, defectors may get stuck in environment terrain but can usually be freed again with additional portals. Also note that certain rooms have 'checkpoints' which defectors will go to even when teleported past them.
    • A slow Nova  build can be quite useful for keeping the Infested off of the defectors.
  • MirageIcon272 Mirage's Eclipse130xDark Eclipse with the Mod TT 20pxTotal Eclipse augment can help defectors' survival on longer defection runs. An extended duration and range build is recommended to ensure a whole cluster of defectors gets the bonus per individual cast.
  • Destroying containers can drop additional powercells as well, including Large ones.
  • OberonIcon272 Oberon's Renewal130xDark Renewal can give the defectors very high health regeneration allowing them to out-heal most of the health drain they experience. This can also allow them to out-heal other damage sources such as toxin clouds, etc.
  • EquinoxIcon272 Equinox's MendMaim130xDark Mend & Maim is a powerful damage dealer and crowd control against Infested, while also providing great amounts of healing for whole clusters of survivors. Coupled with PacifyProvoke130xDark Pacify & Provoke's damage reduction potential, extremely useful on melee enemies, she can allow for the survivors to outlive even Syndicate attacks.
  • Stims are currently the only way to affect the movement speed of survivors. However their high build cost and underwhelming effect make them questionable for use.
  • FrostIcon272 Frost's SnowGlobe130xDark Snow Globe can be used to set up an area of protection over the healing stations. With the added benefit of slowing down any infested that enter, making them easier targets for yourself and allies to attack.
  • KhoraIcon272 Khora's Venari130xDark Venari can be used to heal defectors and will follow them until they reach the evacuation area regardless of the distance between Khora and Venari, allowing you to leave the defectors and attend to other matters.  
    • Strangledome130xDark Strangledome is an excellent way of dealing with the incoming infested. 
    • KhoraIcon272 Khora's movement speed boost passive is useful for traversing to and from the objectives.
  • LimboIcon272 Limbo's Banish130xDark Banish affects defectors for the duration, defectors in the Rift won't be damaged from enemies not in the Rift. It may be necessary to occasionally get them out of the Rift (by casting Banish on them while you're in the Rift yourself), as they can't be healed by Med Boosters otherwise. You could also use other ways of healing, like equipping Limbo's Mod TT 20pxRift Haven augment or use Vazarin's Protective Dash.
    • Defectors in the Rift will still take damage over time from the air however.
    • A variant of this usage, banishing all the enemies nearby into the Rift but not defectors will also work.
  • GarudaIcon272 Garuda's BloodAltar130xDark Blood Altar can quickly heal the defectors by using infested in their path
    • Blood Altar can also be used to temporarily disable manics and red veil operatives, preventing them from killing defectors.
    • SeekingTalons130xDark Seeking Talons is a powerful damage dealer and crowd control against Infested.
  • NezhaIcon272 Nezha's WardingHalo130xDark Warding Halo with the Mod TT 20pxSafeguard augment can help to protect defectors from enemy damage and status effects (such as Ancients' knockdown attack). Additionaly, it will continuously stagger and deal damage to nearby enemies.
    • Health drain from the air still passes completely through this shield, as it does with other abilities listed here.
    • WardingHalo130xDark Warding Halo is casted on each defector separatedly. Therefore, it must be used at least 3 times per squad, making this strategy highly dependend on energy. Due to this, increased Ability Efficiency and Ability Strength is recommended. Ability Strength influences durability of the shield, as well as periodical damage it deals to nearby enemies.
    • DivineSpears130xDark Divine Spears can be used as AoE crowd control.
  • Vazarin's Protective Dash will both heal and provide a brief immunity to survivors.


  • When running solo, there is only one squad that consists of 3 Kavor defectors that need to be evacuated throughout the mission regardless of its rotation and amount of med boosters available.


  • The Shuttle Bay room used as the evacuation point is the same room used on Capture missions as the target's escape room.
  • Defectors who are allowed to bleed out for too long die, causing a special Infested Carrion Charger to spawn from a pod from their body. These special chargers have their own codex entry that requires 3 scans.
    • If revived and allowed to reach the bleed out stage again, defectors will instantly die and turn into said Charger upon death.


Patch HistoryEdit

Update 25.7

Update 25.3

  • Fixed AI traffic jams in the Grineer Asteroid Defection tileset as reported here

Update 25.0

  • Non-Endless Survival/Excavation/etc missions (i.e. Alerts, Sorties, Syndicate dailies, etc) now disable individual extraction as it leads to unnecessary Host migrations

Update 24.4

Individual Extraction - Non-Wave Endless!

You are now able to extract from Survival, Excavation, and Defection missions independent of your squad.

  • Once the 'mission complete' interval is met, players can head to extraction any time they choose (i.e 5 minutes for Survival).
  • Any player at extraction triggers a countdown timer.
  • If all players leave the extraction zone, the countdown timer is cancelled.
  • When the timer is up, the extraction ship arrives and any players in the extraction zone leave.
  • Anyone still playing can extract later any time they choose.

Hotfix 24.2.7

  • As per feedback, Harrow’s Systems Blueprint has been added as a Rare drop in Rotation B for Defection missions. This means you have 2 chances in the Endless loop to obtain Harrow, not just one at Rotation C. To maintain balance, a Bane of Corrupted Mod has moved to Rotation A.

Update 19.12
