Defend an important target against waves of enemy units. If the defense target is destroyed, the mission automatically fails. Every 5 waves choose to stay and fight or extract from the mission.

—In-Game Description

Defense is an Endless Mission type in which the players must defend the assigned primary objective or objectives from being destroyed by attacking waves of enemies. The wave will be considered cleared when all the enemies in the wave have been killed.

Every 5 waves each player will receive an option to either leave the mission individually and receive a displayed reward or to continue for more rewards against progressively harder enemies for an additional 5 waves. The mission is considered completed when players accept the offer to claim a reward and exit.

If you decide not to extract but subsequently fail to clear the next set of waves, you lose any rewards accrued for the waves already cleared, fail the mission and leave with nothing.

Defense Types

There are a total of 18 unique Defense maps for fifteen Tile Sets available.

Nine of them are mostly specific to the Grineer:

  • A: Grineer Galleon; Defend a cryopod at an elevator platform in a galleon's ventilation complex.
  • B: Grineer Asteroid, Cave; Defend a cylindrical Orokin reactor in a dark cave.
  • G: Grineer Settlement, Shelter; Defend a cryopod within a metallic shelter, with entrances all around.
  • I: Grineer Shipyards; Defend a cryopod sitting on a tram in a multi-decked shipyard, the tram may move after every wave.
  • J: Grineer Forest, Shelter; Similar to the Grineer Settlement, with an open roof.
  • Grineer Sealab
    • O: Excavation Site; Defend 4 cryopods located in different corners of an Orokin excavation site.
    • R: Defend an embryonic injector within a cloning lab.
  • P: Orokin Moon; Defend a cryopod on an Orokin platform in the middle of a crater on the moon.
  • Q: Grineer Asteroid Fortress; Defend a Kuva injector in a Grineer fortress. This area has traps that can harm the player: turrets, tesla coils that electrify the floor around the injector, flamethrowers and toxic gas sprays in the corridors.

Six (and two which were removed from the game) are mostly specific to the Corpus:

  • C: Corpus Ship (Old), Cargo Bay; Defend a cryopod on a raised platform, with two main avenues of approach and 2 approaches from behind. [Superseded by Temple defense when the Corpus Ship tileset was remastered.]
  • S: Corpus Ship, Temple; Defend a cryopod on an elevator platform in the middle of a large square room. [Supersedes Cargo Bay defense.]
  • Corpus Outpost:
    • D: Ravine; Defend a cryopod out in the open, surrounded by snowy caves and cliffs.
    • E: Courtyard; Defend a cryopod in a courtyard in a frigid Corpus outpost.
    • F: Dam; Defend a cryopod in a frozen dam complex, with enemies storming across two bridges.
  • H: Corpus Gas City (Old), Deck; Defend a cryopod on the multi-level deck of a gas city ship, with enemies approaching from three ascents. [Superseded by Dynamo defense when the Corpus Gas City tileset was remastered.]
  • T: Corpus Gas City, Dynamo; Defend a cryopod on top of a lightning harvester. A console beneath the cryopod can be activated once every few minutes to electrify the cryopod platform for several seconds, dealing heavy damage to anyone standing on it. [Supersedes Deck defense.]
  • N: Corpus Ice Planet, Shipwreck; Defend a cryopod just outside of a landed shipwreck.

Two are specific to the Infested:

  • K: Orokin Derelict; Featuring walkways and man entrances towards a cryopod on at the center of a stand
  • L: Infested Ship; inside a badly damaged Corpus Ship overrun by the infested with narrow paths towards a large room

The last one is specific to the Orokin

  • M: Orokin Void; featuring a large room with laser defenses that will instantly kill anybody, Tenno included. 4 distinct paths converge down towards the cryopod.)

When an Infestation outbreak is occurring on a defense mission, the infested use the original tile set.

The maps A, B, E, G, L, N, P, Q, R and S have the objective in the center where enemies come from every direction, while the maps C, F, H, I and T are not so open to approach and have the defense objective near the edge of the map where enemies can't spawn and thus making them often more easy to defend. Maps A and S also have a moving objective, where the elevator platform can randomly raise or lower the objective to a different position every wave.

Map D has 3 different locations where a cryopod can randomly spawn: one is in the lower area of the map, one is in the upper area of the map, and one is up on the raised platform above the upper area.

  • The lower area has 3 avenues of approach (the vast majority of enemies only come from 1 direction - this is the easiest location to defend on this map).
  • The upper area has 4 avenues of approach (enemies are more spread out among the 4 - this is generally the hardest location to defend).
  • The raised platform only has 2 avenues of approach and MOAs can jump up the side of the platform as well (the majority of enemies only come from 1 direction - this is the second easiest location to defend).

Map E also has 3 potential locations for the cryopod; either on the center platform where the two shorter bridges meet, or on either of the corners where the long bridges and center bridge meet. The center location is by far the easiest, as enemies are funneled through the short bridges. The corner areas are more challenging as enemies come from both of the bridges, including the small walkway along the long bride, climbing up from the ravine as well as flanking from the upper areas above the cryopods.

On map I the cryopod is sitting on a tram that randomly moves along a rail between 2 locations.

  • The tram usually stays in one location for multiple waves, with a chance of moving at the end of a wave. Tenno can also ride the tram while it's moving.
  • The cryopod will always spawn in the same location.

Map O has 4 cryopods located on 4 separate corners of the map. After each wave one of the four cryopods is randomly selected to become vulnerable to attack, indicated by a blue aura surrounding it, and will become the current enemy target. Players must thus move to each vulnerable Cryopod as they are marked every wave in order to defend them.

Map P has a single cryopod in the middle of a platform which collapses every 5 waves. Wave 6 has the platform collapse into an Orokin complex while Wave 11 has the platform fall into a huge moon cave. The platform does not fall any further after wave 11.

Currently there are several planet-exclusive defense maps:

  • Grineer map G is available only on Mars.
  • Corpus map T is available only on Jupiter.
  • Grineer map I is available only on Ceres.
  • Grineer map J is only available on Earth.
  • Corpus map N is only available on Europa.
  • Grineer maps O and R are only available on Uranus.
  • Grineer map P is only available on Lua.
  • Grineer map Q is only available on the Kuva Fortress.
  • Infested map K is only available on Deimos.
  • Orokin map M is only available in the Void.

There are a total of 28 Defense Missions

There are a total of three tiers which determines the reward pool players have access to at each 5th wave checkpoint.

Extraction

At the end of each round, the decision screen indicates what each individual player intends to do, with undecided players continuing to battle. It is not a vote and extraction occurs for individual players, not the group; these players will appear to disconnect. It is normally advised to decide on a leaving wave before entering the mission or alternatively shortly after it starts. If not, then everyone should leave at the same time as soon as one of the party members decides to extract.

Significant lag may prevent this option from appearing entirely for clients if the latency is from the host of the match, and the players will be forced to stay and have a host migrate. Keep this in mind if you join a match and notice an unusually high amount of latency.

Rewards

Rewards from Defense missions are offered every 5 waves during the extraction prompt. If a player chooses to extract, they receive the reward for that particular wave along with rewards offered from previous extraction prompts on that mission. The order of the rotations is AABC.

  • The percentages display the chances of a particular item being received as a reward during each extraction prompt.

Dark Sector Defense

Defense missions that take place in Dark Sectors always involve the Infested. These Defense missions have a higher level range (and thus, higher difficulty) than the planet they're found on, but give out larger quantities of experience, including the experience bonuses inherent in Dark Sectors, and have a chance to reward melee mods which cannot be obtained outside of Dark Sectors.

Wave Defense

Wave Defense is a variation of the normal Defense rules, commonly found in Nightmare Mode, Invasions, and previously Alerts. Instead of starting at wave 1 and counting up until the players extract or leave, the waves start at a predetermined number and count down to 1, after which the mission ends automatically. There are no mission rewards until all waves are completed. This mission type was first introduced in the Artifact Defense Event.

The following Defense variants, organized by the number of waves, operate by Wave Defense rules:

Notes

  • Defense missions are considered some of the best missions for mod farming due to the unlimited amount of enemies and the ability to easily leave after each 5 rounds.
  • As of Update 9.0, enemies will now swarm the pod or reactor much more aggressively, with more enemies running up to the defense objective and attempting to destroy it. Also due to update 9, enemies will increase in level with each wave faster then before.
CBring
  • The first wave will start when one of the players have reached the activation "ring" around the objective, or when 3 minutes have passed. Players are free to loot all the resources around the map before activating the first wave by stepping into the ring.
  • As of Update 9.7, enemies can jump onto boxes and ledges, including many "safe zones" (such as the platform on the bottom right of the picture) making it even harder to avoid damage.
  • Update 9.7 also made it possible for enemies to walk onto and across the large railbox (top left of the picture) providing another (and quicker) way for enemies to reach the pod, and that pathway is more difficult to defend.
  • As of Update 12.0, the being inside any cryopods has changed from a human to a humanoid wearing a gold and black suit, similar to the color scheme of primes.

Bugs

  • There is a bug where you will click to exit the defense mission, but you will stay in the mission without a HUD, and sometimes not being able to move or chat at all. Dying will not bring back the HUD and you will not be able to revive. The only way to leave the mission is to force close the game using Alt + F4 or through a process manager.
  • Having the chat window open and active while in the process of choosing between 'Extract' or 'Battle' will result in the typing player ending the mission as if they chose 'Extract', even if they chose 'Battle' explicitly.
  • A test mod card labeled "Ancient Retribution" may show up as a reward, although it cannot actually be rewarded and claiming the card may crash the game or cause instabilities afterwards. The card is used by Digital Extremes for testing and does not actually represent a real mod now or in the future.[1]
    AncientRetribution
  • Infested Leapers have a tendency to leap into the Warframe Cryopod which the player/s is/are supposed to be defending in the Dark Sector Defense nodes where the defendable object is a Warframe Cryopod. They will leap straight through the Cryopod and end up in the middle of it and will proceed to swipe at the center of the Cryopod, often spinning around the center of the Cryopod and taking no direct damage simply from being there. It has been tested on multiple levels that Leapers which end up in the center of the Cryopod seem to take more damage from Primary and Pistol weapons than they otherwise would.
  • Many Defense mission tilesets can spawn enemies that end up getting caught inside walls or other terrain, and need to be killed with an AoE weapon or ability to continue the mission.

Patch History

Update 28.3

  • The Defense alarm will now sound at the start of every Wave in Orokin Defense missions.
  • Fixed Defense mover objectives (Gulliver on Phobos & Hydron on Sedna) affected by Limbo’s Rift continue to take damage regardless of Rift status.

Hotfix 28.2.1

  • Fixed an issue where Defense Targets on moving platforms would not move with the platform if a Host migration occurred while it was not in the default position.

Update 28.1

  • Fixed broken Defense objectives in Corpus Ship missions after a Treasurer spawns and the squad migrates.
  • Fixed enemies in the Corpus Ship Defense tileset sometimes getting stuck on door frames.

Update 28.0

  • Fixes towards Defense missions breaking due to an inability to terminate enemies that have been changed to Ally status (Nyx Mind Control, Revenant Enthrall, etc), thus inability to complete the Defense Wave.
  • Fixed Clients not seeing the dynamic Damage effects when the Defense Target's Health gets lower in tiles where the Target moves.

Hotfix 27.3.7

  • Fixed areas disappearing when viewed from long distances in the Hydron Defense tileset.

Hotfix 27.1.2

  • Fixed cases of the Defense target getting stuck in an infinite falling loop in the Sedna Adaro Sortie Defense mission.

Update 27.1

  • Fixed an issue where the Defense target's head would float above the cryopod in Defense missions, exposing it to the many dangers of the environment and also the dangers of not having your head connected to your body.

Hotfix 27.0.12

  • Defense Waves will now complete if NPCs are downed (but not dead), except for the final Wave, where all NPCs must be taken care of.

Update 25.7

  • Defense used to use the base node for enemy count scaling, now difficulty properly scales alongside current enemy level - meaning that the higher the enemy level, the more simultaneous enemies you’ll have to face!
  • New players can now join Defense missions until the second Wave instead of the fourth Wave to guarantee enough time to collect Reactant during Void Fissure missions.
  • Fixed a loss of functionality when using a controller and spamming Y as the round timer runs out in endless missions (Defense).
  • Fixed issues with Nova escaping certain maps for easy-mode Defense.

Hotfix 25.3.2

  • Fixed enemies not spawning after a Host Migration in the Grineer Shipyard Defense tileset.
  • Fixed Cryopod alignment in the Gas City Defense tileset.

Hotfix 25.2.3

  • Fixed overly aggressive optimizations that could lead to graphical popping of certain meshes in the Void Defense tileset.

Hotfix 25.0.8

  • Fixed Ivara’s Cloak arrow functioning on Defense objectives, leaving enemies unable to find it.

Update: Specters of the Rail

  • Added a new 'Wave Cleared' sound for Defense missions.

Update 17.0

  • Waves will now start with weaker enemies, progressing to support units and ending with heavy and Eximus units to make the end of the wave more intense.
  • The number of enemies attacking the player has been increased for early-waves and decreased for later-waves; this should not only improve performance on systems but brings the duration of a 20-wave Defense Mission closer to 25-30 minutes.
  • The progression of enemy types in all defense missions has been tuned.
  • For more information these changes, please see our Developer Workshop here: https://forums.warframe.com/index.php?/topic/495562-defense-experiments/

Update 16.9

  • Players joining an Defense Mission mid-progress will now only be able to join before the start of the 4th enemy wave- after then the mission is considered 'objective complete'.

Update 15.0

  • Defense and Interception Mission rewards now stack! This removes the "inventory checkpoints" every 5 waves in Defense -- it's all or nothing now. The Reward Rotation for Defense and Interception has also been changed (to be like Survival) as Stacking Rewards is now in place. The Rewards now rotate through the reward tiers.

Update 14.0

  • Added Eximus/Leader spawn scaling to Defense missions.

Update 11.6

  • Changed enemy scaling for Endless Defense missions at high levels (now wave 100 enemies should be around level 200 instead of 8000).

Update 11.1

  • New Corpus Survival and Defense squads using new U11 enemy types.

Update 11.0

  • Time between Defense waves has been reduced to 6 seconds

Update 9.5

  • All Objectives in Endless Defense now scale to the mission's enemy level - higher end defense should now be slightly more tolerable for solo play or squads without Frost. Does not scale with additional enemy scaling per wave.

Update 9.4

  • Defense missions now begin when the pod/core is reached, meaning idlers do not determine when mission begins. One player must reach the defense target for the first Wave to start

Update 9.0

  • Enemies will storm the defense targets, which makes them much more aggressive towards it.

Update 8.1

  • Defense mission reward tables have been reviewed and changed. Reward tables are now split between factions. Fusion cores have now been added to the drop tables.

Hotfix 7.8.1

  • Inventory Checkpoint for Endless Defense added. Reaching every fifth wave (5, 10, 15…) locks in rewards earned to that point.

Update 7.2

  • Enemy variety now changes as players progress through waves of Endless Defense
  • Ciphers should no longer appear as rewards when completing high level waves of Endless Defense

Update 7

  • Endless Defense - a new defense mission type. Survive longer for escalating rewards!
