Invasion is a mission type that allows players to side with either the Corpus or the Grineer to work against opposing factions, as they invade (or defend) a specific mission sector, earning players a reward based on the offering of a single chosen side. The Infested also are able to invade, although players cannot side with them.

Invasions were first introduced in The Gradivus Dilemma and officially added to the game in Update 11.3 (2013-12-12). Note that Earth is not eligible to have invasion nodes.[1]


Invasion Missions are essentially a modified version of regular ones where both opposing factions are presented on a battlefield. During the mission, the player is aided by the faction they sided with (i.e. siding with the Grineer will give you Elite Lancers and Heavy Gunners allies, among others) as they attack the enemy.

If the player is ambushed by any Assassin or Syndicate death squad during an Invasion mission, allied NPCs will aid the player in fending them off, even if they are from the same faction (the Grineer will attack The Grustrag Three, for example).

Tileset specific enemies like Bursas and Prosecutors will always fight along with the player, when they have sided with their respective faction.

In Corpus and Grineer invasions, the mission type for a particular node changes every 15 minutes.[2] Possible mission types are Exterminate, Capture, Defense, Rescue, Interception, Sabotage, and Spy. Rescue missions will start the execution timer upon entering the prison tile, similar to Sorties. Sabotage mode involves destroying a reactor core located on the enemy ship, with only one coolant cell, unlike regular Sabotages that use Reactor Sabotage for Grineer Galleon and Corpus Ship tilesets. Spy missions feature a single data vault located on the enemy side of the map.


Any ongoing invasions are listed in the Operations window, with the Invasions tab located between the Alert and Syndicate mission tabs. Alternatively, players may select planets with the symbol of the attacking faction to view the contested sectors. Both sides offer payment for supporting them in contested locations. Selecting a conflict location will present a choice of sides and their respective battle pay, including rare Blueprints, Resources, and parts of Wraith and Vandal weapons.

Players will need to commit to a single side to earn battle pay by completing 3 missions. Switching sides will reset the player's rating with the opposite faction and deny players either reward. Completing more than the required 3 missions per invasion will not increase or improve the reward by any means. Players will receive the battle pay of the faction they side with, regardless of which faction wins the invasion.

The attacking faction is represented on the left, with a percent of capture. The faction being attacked is represented on the right. Once either side reaches 100%, the invasion ends and the node returns to its regular mission type.

Infestation Outbreaks[]

Infested missions were largely cleared from their Solar Map locations in Update 11.3 (2013-12-12) and replaced with Operations using the Invasion mission mechanic. During these, the faction being invaded will assist you in dealing with the Infested threat. Unlike standard Invasions, Infestation Outbreaks spread between sectors much faster than Grineer or Corpus invasions, and can often see an entire planet covered with Infested missions fairly quickly.

Infested Invasions will always inherit the sector's mission type if the preexisting sector was Exterminate, Defense, Mobile Defense, or Survival. If the contested sector mission type was not one of those, the game will decide randomly out of those 4. Assassination mission types use Phorid as the assassination target and will appear over the planet's standard Assassination mission.

Tile Sets[]

Invasions on Corpus Ship and Grineer Galleon tilesets feature unique map tiles that connect the two opposing vessels of each side, serving as a transitional tile from one map tile into the other, i.e. changing from Grineer Galleon to Corpus Ship and vice versa. Each invasion sector has its own variant of these connecting tiles, which does not change for missions performed on that tile until the invasion ends.

  • Variant A features a large asteroid mining base connecting the two ships, with plenty of open space and side paths for large engagements. This tile features an energy field that blocks the main path that must be dispelled by hacking a nearby control console. Alternately, there are hidden paths accessible only by parkour that allows players to bypass the field completely.
  • Variant B features a direct connection between vessels by a Grineer boarding tunnel, leading to a heavily damaged Corpus room.
  • Variant C is encountered when siding with the Corpus on certain invasions, which features an access tunnel that periodically pulses with energy that can damage player shields. This tunnel exits into the outside of the Corpus Ship that is exposed to space, draining player shields the longer they stay. This then leads to a large glowing portal that transports the players directly into the barracks complex of the opposing Grineer Galleon.
  • Finally, Variant D is encountered on the same sectors as Variant C, but when siding with Grineer instead, involving a large room with massive cannons firing boarding pods similar to the Ramsled deployed by enemies in Empyrean missions. Players can board an empty pod and initiate the launch sequence by activating the control console inside; this closes the pod, which after a few seconds is fired directly at the opposing Corpus Ship. After the transition, players can exit the pod into the Corpus Ship via a breach made on its hull.

Note that both Variant C and Variant D prevent backtracking into the allied ship as both their transition areas only allow one-way travel.

The Gradivus Dilemma featured an additional variant featuring an asteroid cave connecting the two ships, which has been implemented in standard invasion missions with the Grineer Asteroid tileset as the main tileset.

Infestation outbreaks on Corpus Ships also feature a unique transitional tile, which takes place on a large shuttle bay with an equally large glowing portal at the end, that transports players into another ship. These missions also feature a unique starting tile, which holds a secret room inside an elevator shaft.


Once a victor for a node has been decided, the player will receive their reward in the inbox regardless of who won the sector. However, the player will attract the attention of either the Zanuka Hunter or The Grustrag Three depending on who they sided with in Grineer/Corpus invasions respectively and may be ambushed during a later mission. Players may also get the Stalker's attention by defeating Phorid.

Also, the winning faction will occupy the targeted node for 24 hours and will eventually contribute towards a Construction Status, which is a "toll" that will be taken by the players at a later time for supporting the Grineer or Corpus. This contributes towards a Balor Fomorian or Razorback Armada respectively. Each will appear near a targeted Relay once the Construction is complete, and the Lotus will warn all Tenno about the threat via Inbox message. This message also includes an item blueprint required to access the specific node, for either the Fomorian Disruptor or the Razorback Cipher.

Construction Status[]

The Construction Status is a meter that is globally contributed by all players in the community. When the meter is full, a special 3-day alert, the Fomorian Sabotage for the Grineer and Razorback Armada for the Corpus, will happen where an enemy faction attempts to destroy a Relay. Players will earn Credits64 200,000 and an OrokinCatalyst Orokin Catalyst upon completing the event's listed goal (inflicting 1,000,000 points of damage in a single session for the Fomorian Sabotage or destroying 3 Razorback bosses for the Razorback Armada).

Each successful completion will decrease the enemy's integrity, and, as with the Construction Status, the integrity meter is community contributed. Once the integrity of the Fomorian fleet or Razorback Armada reaches 0%, the event will end and reset the Construction Status of the respective faction.

Failure to destroy the Balor Fomorian or the Razorback Armada within the allotted three days will result in a loss of a Relay. However, this only happened four times in the entirety of Warframe's history when Fomorian Sabotage was introduced in the Operation: Eyes of Blight in Update 15.



The below table shows the chances that an invasion node may have a particular reward for completing three missions for one side of conflicts. Rotation A corresponds to rewards from siding with the Grineer, rotation B is for siding with the Corpus, and rotation C is for completing any Infestation Outbreaks.[3]

Drop tables outdated? Readers can update Module:DropTables/data and cross reference with official drop tables on https://www.warframe.com/droptables.


  • The number displayed on the navigation bar is the number of planets involved, which appears to be functionally irrelevant, not the number of missions nor the number of missions of which you haven't done 3 or more. This makes it difficult to track when new invasion missions are available.
  • Some invasion missions, particularly the ones you wouldn't want to miss due to an impressive reward, can be finished surprisingly quickly so, in the absence of a functional number on the navigation bar, to avoid missing something useful you have to check each invasion planet frequently.
  • As of Update 11.6 (2014-01-08) factions now have momentum, giving the leading faction a periodically increasing score. This was added to avoid faction stalemates and allow the invasion system to move to different locations.
  • Barring Infestation Outbreaks, Environmental Hazards such as fires are guaranteed to occur in any given invasion.
  • Invasions are a good time to codex scan the faction you are sided with, as they will hold still while not attacking.
  • Invasions also seem to have a higher chance to spawn rare containers and Ayatan Sculptures. Many users reported finding rare containers and sculptures, especially on invasions.[citation needed]


  • If Phorid invades, it will list Phorid as the 'Faction', not the 'Target'. It is also called Phorid Manifestation.
  • The diorama for Corpus invasions contains a graphical error; FluxRifle Flux Rifles can be seen firing as if they were Dera Dera rifles.
  • If the player is playing an unaffected node on a planet that is under siege, the invading enemy can appear in the mission. This does not affect the goal of the mission.
  • Prior to Update 14.0 (2014-07-18), the faction that won a contested node would take over that node until another invasion overthrew them, effectively replacing the previous faction owner as a result. This may have been changed to a temporary takeover to avoid disrupting mod drops on a planetary scale – one infamous case had all of Europa taken over by the Grineer.
  • Grineer invasions are called Grineer Offensives, whereas Corpus invasions are called Corpus Sieges.
  • The mission type was officially announced in Livestream 16. Livestream 17 mentioned the possibility of the Invasion game type returning, but as alert-only as opposed to replacing a preexisting game type.
  • Fomorian Sabotage and Razorback events are manually started by the developers and do not immediately launch when construction statuses reach 100%.[4]


  • The Grineer Breach Pod tile is prone to bugs due to moving parts, especially when playing as a group, most likely due to synchronization errors.
    • Often the players' pod won't load into the launcher. There is no discernible player-made cause for this.
    • It is also possible for one or more players to get left behind in the empty launcher if multiple players are in the pod when it launches.
  • The Corpus portals on the same map as the Breach Pods are consistently buggy and generally won't allow you to pass through, performing the same action as falling too far below a map and teleporting you back to the ground before forcing you to jump through it again.
  • If the last mission to receive battle pay is completed after the invasion node returns to normal, you will not receive the battle pay.
  • If an Infested invasion occurs on a Crossfire mission, the Infested will appear as Orokin in the factions section.
  • If an Infested invasion occurs on an Exterminate mission, the Lotus may say "The area is crawling with Infested. If it's not a Tenno, eradicate it." at the start of the mission despite there being Grineer/Corpus allies on the field.
  • On rare occasions, you will receive the reward from an invasion that you have only ran one mission for.
  • Due to the way each planet in the invasion list expands on screen and then shrinks the moment you've moved below it, if you move from the top to the bottom the ones displayed can skip entire planets, so to be sure of seeing all the planets it's recommended to always start at the bottom and move up.

Invasion Changes

With the precedent already set from Fissure missions for rewarding per normal endless cycle, Invasions felt strenuous due to their lengthy mission completion requirements. Considering there are other “faster” mission types available to get your reward and get out, it was time to cut back a bit on the way 'endless' variants work within the system. As a result, the following mission completion requirements have been scaled back:

  • Defense from 10 waves to 5 waves
  • Survival from 10 minutes to 5 minutes
  • Interception from 2 rounds to 1 round
  • Excavation from 1000 Cryotic to 500 Cryotic

Update 19.0 (2016-11-11)

  • Prior Sortie Season Vandal and Wraith rewards can now be offered as invasion rewards by the respective faction.
  • Interception missions have been added into the mix when playing for invading faction.
  • Winning factions will now 'Occupy' the node for up to 24 hours. During this period, the invaders will raid the location for resources towards a mysterious 'Construction Project'
  • The mission type at a particular Invasion node will change every 15 minutes.
  • The progress of an invasion can now lead to a Faction Specific event.
  • Factions now pay an additional 1000 Credits each time you run a mission for them on the same node (up to max of 10K).
  • Fixed issues with Invasion missions loading to black and no spawning enemies.
  • Fixed Invasion progress not counting if a player was in mission during a Hotfix.
  • Fixed Phorid occupied nodes still showing the underlying bosses.

Update 12.2 (2014-02-19)

  • Omitted Venus/Earth being eligible for Grineer or Corpus invasions to not throw off new player path.

Update 11.8 (2014-01-22)

  • Server-side change on 1/20/2014: More frequent Grineer vs. Corpus invasions. Originally invasion system allowed for 2-5 days of downtime, this has been changed to only allow 1-2 days downtime.

Update 11.6 (2014-01-08)

  • Improved Faction invasion momentum by periodically increasing score for leading faction by a small amount (since numerous stalemates have emerged which interfered with the flow of the system).

Update 11.5 (2013-12-19)

  • Infested Invasion missions now only require 3 completions for Battle Pay instead of 5.
  • Infested Invasions will always inherit node mission type if the preexisting node was: Exterminate, Defense, Mobile Defense, or Survival. If the node being Infested was not one of those, game will decide randomly out of the 4 (Exterm, Defense, M. Defense, Survival).

Update 11.3 (2013-12-12)

Systemic Invasions 1.0 is live!
  • Grineer & Corpus now periodically attack star chart nodes owned by opposing factions; if successful, battlefront moves to an adjacent node, otherwise faction "rests" before attacking another node.
  • The Infested now truly infest! The faction has vacated the Star Chart and now exists as an Invasion faction! Keep your eyes peeled for signs of Infested threats – they’ll strike hard.
  • Infestation "outbreaks" will occur at random, with a downtime of 12 – 36 hours between attacks. When a node is under Infested threat, battlefront aggressively moves to all adjacent nodes if invasion isn't successfully defended within a matter of hours. Outbreaks continue to spread until reaching a boss node, which leads to Phorid appearing and occupying that boss's node until the invasion is defeated!
  • This system is a new dynamic we’re trying out and will be standing by for feedback/suggestions accordingly.
