For the playable Stalker, see Stalker (Playable).

The Stalker is an ominous, vengeful figure that infrequently appears during missions, armed with powerful weapons and abilities to hunt down Tenno who have his Death Mark.

The Stalker is a sapient Warframe and is able to use ability powers belonging to various other Warframes. His arsenal is similar to that of the Tenno, utilizing a primary, secondary, and melee weapon. The Stalker's signature weapons are the bow  Dread, the scythe  Hate, and the throwing knives  Despair.

If the Tenno marked for assassination has completed The Second Dream Quest, they will be confronted with the more powerful, Sentient-enhanced Shadow Stalker instead. Upon completing the Jade Shadows Quest, Stalker will appear as Protector Stalker, having reverted to his original appearance, with his mask and  Hate imbued by  Jade's energies.

Lore

General

Before he became the Stalker, he was once a Low Guardian named Sorren who served the Orokin, and was engaged in an unsanctioned relationship with an individual known as  Jade, with whom he sired a child, which the Orokin legems considered taboo. They were caught by Ballas who turned them into Warframes as punishment; blaming himself, the Stalker repents and served as the Orokin's devoted dog in hopes Ballas would allow him to reunite with Jade and their child.

During The Collapse of the Orokin Empire, he noticed that the Tenno weren't as stoic and silent but instead waiting and poised, but failed to warn his masters of the slaughter the Tenno were prepared to carry against them. The Tenno went in pursuit of him as well, but he was rescued by Jade in his time of need.

However, he did not recognize Jade and believed the Orokin's downfall dashed any hopes of reuniting with his family. Therefore, the Stalker sought vengeance against the Tenno and hunted their numbers across the Origin System.

The Second Dream

The Stalker allies with Hunhow and is bestowed the  War greatsword while upgraded with Sentient powers, transforming into the Shadow Stalker. As they scheme to destroy the heart of the Tenno, the Lotus receives assistance from Alad V, but fail to stop the Shadow Stalker from revealing the Tenno's weakness: the Reservoir on Lua, hidden by the Lotus in the Void.

Upon discovering the Tenno's true form, however, the Shadow Stalker hesitates, confused if he himself was a Tenno. He leaves, but later resolves himself to fight the Tenno on board their Orbiter. He gains the upper hand until the Warframe destroys the greatsword, causing the Stalker to seemingly experience immense pain before vanishing.

Operation: Shadow Debt

For Alad V's interference in The Second Dream, the Stalker sends his Acolytes - warriors as mysterious as the Stalker himself - to hunt him. Alad V invokes his favor from the Tenno and has them repel the Acolytes.

The New War

The Stalker still serves under Hunhow after the fall of Origin System and the rise of Narmer. He has reverted to his original appearance, though Hunhow still addresses him as his Shadow. He slaughters Narmer forces led by Ka-Nuteru, who were hunting the Stalker.

To protect the Lotus from Ballas, Erra, and Narmer, Hunhow allies with the Drifter. The Stalker gives them the  Nataruk bow and assists them in fighting Erra's Archons.

Duviri

Through the mysterious powers of the Void and Conceptual Embodiment, an unlikely ally in the form of the  Stalker "Warframe" is able to appear in Duviri and lend his assistance to the Drifter.

The Reaper's Lament

Hunhow, feeling regrets with his own family, urges the Stalker to make amends with the Tenno, to wield the scythe once more (an instrument of cultivation, growth, and love, unlike  War that only kills indiscriminately), and let go of the past, as the Orokin weren't worthy of his loyalty. When the Stalker refuses, Hunhow warns that he will always have a target painted on his back and that his "actions will have consequences".

Jade Shadows

Stalker continues to secretly care for the Warframe who saved him, known as  Jade, whose health is deteriorating from unknown causes. Despite Hunhow's suggestions, he raids a Corpus ship for medical-grade bioplasma, catching the attention of a Captain Xeto, though the bioplasma fails to revitalize Jade, while Corpus forces track him down to his lair, and he eradicates the initial raiding party.

As per Hunhow's advice, he teleports onto the Tenno's Orbiter, and after avoiding Ordis, sneaks into the Transference Room and confronts the Operator and convinces them to help Jade. The Operator directs Stalker to harvest Cortichrome from an Infested Juggernaut Behemoth. Xeto also tracks down Stalker and deduces he is attempting to heal someone, and sends Corpus forces to occupy his lair.

When he arrives however, the Operator informs the Stalker that whatever is draining Jade's life force, she is not fighting against it. When the Stalker demands the Tenno try helping her anyway, their solution ends up not being enough to save Jade; she is revealed to be pregnant, her declining health implied to be caused by the baby she is carrying. She passes during childbirth, dissolving her form and leaving behind an infant baby.

The newfound baby seems to empower Stalker with parts of Jade's power making him and his weapon glow green as he begins fleeing with the child, fighting the Corpus who have occupied his lair in the meantime. When he emerges from the elevator at the surface, however, Xeto and her crew of Corpus fire upon him, bringing him to his knees. Upon hearing the child cry however, Xeto commands her crew to stop firing, and they let Stalker pass and board his ship, where he flees.

Afterwards, he arrives on Lua, reliving a past conversation with Jade, swearing to protect his family. He names the child Sirius or Orion.

Hunhow later notifies the Tenno that the Stalker has fled his lair, and claims that he will not be returning.

Spawn Possibilities and Combat

Players will be marked by killing certain bosses during Assassination missions and being given a Death Mark. Then the Stalker can spawn in almost any player-accessible mission. The exceptions which prohibit his appearance are:

• Syndicate and Assassination standard missions
• Archwing, Free Roam and Arena special game mode missions
  • Also includes Quest and Mastery Test solo-exclusive missions
• Non-combat hub "missions" (Relays, Dojos)
• Any mission that has already been determined as "chosen" for the spawn of another Assassin (Grustrag Three or Zanuka Hunter) or is forced to, due to use of their respective beacons
• Sortie missions
• Any mission that has already elapsed his spawn time window of around 5 minutes
• Albrecht's Laboratories missions

At least one squad member must be marked for death by the Stalker before he will have a chance of spawning.

Upon being marked for death, the target Tenno will receive an inbox message from the Stalker (marked as ???). After this message is received, the game will calculate the Stalker's chance to spawn in a valid mission according to the following formula:

Spawn Chance = 1.5% + (0.5% × P); P = Players in Squad marked for death.

Thus with squad line-ups of 1 to 4 marked players the chances of spawn are 2%, 2.5%, 3% and 3.5% respectively for each possible combination.

Like other Assassin spawns there are special screen darkening effects announcing his arrival, although not all effects apply to squadmates. When the Stalker spawn starts, the targeted Tenno will experience the screen briefly flickering in a dark red hue accompanied with a hushing sound effect. Other squadmates will see the screen darken and a faint shadow of the Stalker flickering behind them. The target will receive a transmission, taunting the Tenno in question with threatening messages. After three taunts, the tileset will enter lockdown, and the Stalker will appear briefly invincible kneeling in a puff of black smoke before proceeding to attack the targeted player.

If the targeted Tenno is killed, the Stalker will again kneel and vanish into another cloud of smoke, proclaiming his victory and that justice was served. If his health drops below 10% before he manages to kill his target, he will attempt to flee, announcing his shock at his failure, though he can still take damage and occasionally be killed up until he despawns.

If he is defeated (regardless of whether he successfully fled or was accidentally killed), there is a chance for him to drop various loot items, such as a mod or a resource, or even blueprints for one of his weapons. As a boss, he always drops one Mod from his mod drop table.

If  Jade is present, Stalker will immediately despawn and drop his usual loot.

Abilities

The Stalker appears to don a unique, one-of-a-kind Warframe; completely immune to all Warframe abilities, regardless of whether they affect him directly or indirectly. He is furthermore capable of casting a wide variety of abilities from multiple Warframes, some of them with a unique variant exclusive to him.

His known used abilities are:

•  Slash Dash (variant) – The Stalker will usually start the fight by charging at his target with  Hate, heavily damaging any targets in the way (akin to the version of this ability in previous updates). After this, he will usually switch to  Dread or  Despair. This is an ability belonging to  Excalibur.
•  Smoke Screen (variant) – The Stalker may occasionally disappear from sight during the battle, during which he will use Teleport in tandem to his invisibility to move erratically across the battlefield. This is an ability belonging to  Ash, but with a significantly longer duration.
•  Teleport – If the Stalker is currently using Hate, he will often teleport behind players and use Hate to strike the unsuspecting Tenno. He usually uses this ability in tandem with his Smoke Screen to unpredictably move across the battlefield. This, too, is another ability belonging to  Ash.
•  Reckoning (variant) – Activated roughly 10 meters towards allies who are supporting the victim player. All those who are caught by the ability are held in the initial Reckoning trance for a short duration, allowing the Stalker to resume attacking his target unimpeded. This is an ability belonging to  Oberon but without the slamming.
•  Pull – Rarely used, if the players are out of his aiming range, he may use this ability to pull a faraway target towards him—which in turn stuns the players. This is an ability belonging to  Mag.
•  Absorb – This is the Stalker's desperate and possibly most deadly ability. If he is low on health, he will use this ability to absorb all damage and repels it back towards nearby players, which may prove to be fatal for high-damaging players. This is an ability belonging to  Nyx.

Strategy

The Stalker is capable of dealing significant damage, comparable to a well-equipped Tenno, and can easily destroy an entire squad if they are caught unprepared. It is important to warn squad-mates when the Stalker begins his taunts so that they can prepare for the upcoming fight. It is also important to stay close to other squad members so that if he does manage to take his target down, the squad can revive them before they bleed out. Note that the Stalker will despawn once the targeted player goes down, even if they are revived before completely bleeding out.

There are several ways to deal with the Stalker once he spawns, such as constant movement, tanking, and / or fighting with Melee weapons. The Stalker will often use abilities from other Warframes, which should be avoided if it at all possible.

If the targeted player attempts to run from the Stalker, he will occasionally teleport behind them and engage in melee attacks, similar to the Grineer Flameblade. The Stalker has also been known to  Slash Dash towards a ranged target, dealing potentially lethal damage upon impact. He may also use  Pull to drag his victim back towards him. When in melee combat, Stalker can stagger his target by striking with  Hate at just the right moment. He may also attempt to evade melee combat by back-flipping away from the engaging player. If the Stalker's health gets too low, he can cast  Absorb, forming a shield bubble around him which absorbs all incoming damage and explodes outward, dealing 100% of absorbed damage as  Magnetic damage to players within range, draining their Energy, and inflicting a Knockdown.

When actually fighting the Stalker, it has been found that fighting at range while on the move is particularly useful, as  Dread is less powerful than  Hate and  Despair, all 3 of his weapons can be blocked to negate all damage (note that this does not block potential status procs). In addition, having  Reflection can reflect some of the Stalker's damage back to him, largely eliminating the necessity of risking death in counterattacks with a player's own weapons. Do note, however, that the Hate staggers players who parry its blows, leaving you open to attack.

High burst-DPS weapons such as beam weapons and shotguns are also highly effective; with the right weapons and mod configurations, many players can kill the Stalker before he has a chance to attack. It should be noted that he may use Reckoning to negate taking large amounts of damage.

It is critical to avoid firing on him when he casts  Absorb, as the resulting explosion deals not only the ability's base damage, but also any damage the sphere takes before the explosion and can be very damaging and even fatal.

Other Notes

• The Stalker typically only attacks his marked target, but he has been known to engage other party members and even enemies if the target is out of range or out of his line of sight. This can be used in large rooms or invasions to make the fight easier. All allies in Invasions will prioritize the Stalker (or any other assassin) over regular enemies.
• Players may be able to avoid the Stalker's attacks by keeping 50 meters of distance between the target and Stalker, but due to the frequency of his  Teleport, this may be impossible to achieve.
• It may be significantly harder for the targeted player to avoid or maintain distance from the Stalker when they are the host of a multi-player session, as there is no latency while he targets the player and tracks their movements.^{[citation needed]}
• When Stalker spawns, the current section of the tileset goes into lockdown. Depending on which tileset players are on, there is a possibility that it can be released by Hacking, either manually or with a Cipher.
• If mission objectives are already complete, players can rush to extraction to complete the mission, avoiding having to fight Stalker entirely.
• Taking on the Stalker in Operator form can make the fight easier, though it'd be advisable to make sure your equipped amp is up to the task.

Gameplay

Main article: Stalker (Playable)

A playable version of the Stalker appears in Duviri upon acquiring Drifter Intrinsics Opportunity Rank 10. He is functionally equivalent to a Warframe, with a passive that grants 300% critical chance to enemies that do not see him, and the abilities  Teleport,  Marked (similar to  Marked For Death),  Smoke Screen, and  Punishment (similar to  Nyx's  Absorb).

Notes

• If a player is "taxied" (invited to a node/planet they have not unlocked) to a boss fight, they will not receive Stalker's mark for any boss fight they are taxied to as long as they have not unlocked the planet. If the planet is unlocked already but the node is not when the player is taxied, the boss node and those around it will be unlocked and all subsequent runs of the battle will not earn the player Stalker's mark so long as they are not hosting/playing the mission solo.
• The Stalker can drop the rare resource (save for Orokin Cells which have their own entry on his drop table) of the current planet when defeated.
• There is a delay of 30 to 280 seconds (~4 minutes) before the Stalker will spawn in a given mission.
• The Stalker has a base spawn level of 30 while partially influenced by the level of enemies in the mission his level.
• Normally, upon reaching 10% health, the Stalker will announce his failure to defeat the targeted player, kneel, and disappear in a puff of smoke. An excessive amount of damage that fully depletes his health before he can do this will cause him to fall over similar to a downed player, but he will disappear in smoke either way. He may sometimes glitch in this case; not disappearing, becoming invulnerable and frozen.
• If kept about 10 meters away while in smoke form and constantly taking fire from the player, the Stalker may stop teleporting and simply drift slightly on the spot until he is defeated, making the fight trivial.
• Prior to Hotfix 11.0.5 (2013-11-23), the Stalker had a 5% spawn chance. It has since been reduced.
• As of Update 11.6 (2014-01-08), the Stalker's (and incidentally Zanuka Hunter's) spawn chance was modified from 2.5% flat spawn chance to 1.5% + 0.5% per player. This update also introduced Death Marks for all existing Assassins.
• If more than one player has a death mark from the Stalker, he might target other marked players and kill them if they engage him; however, upon downing his newly selected target, he will immediately leave and his attention will revert to his original target if it is within line of sight.
• As of Update 18.5 (2016-03-04), the Stalker will not appear to attack players using any Warframe under Rank 10.
• A Stalker mark can be gained quickly by repeatedly running the assassination for the Hyena Pack on Psamathe, Neptune, as both Hyenas have a chance to give a mark.
  • The Sergeant assassination on Illiad, Phobos is another assassination mission that can be completed quickly, especially if using  Volt with the Shocking Speed augment.
• If more than one Stalker Beacon is used in a mission, the user will be prompted with an error sound and no beacons will be consumed.
• Death Marks stack. This means that players can acquire Stalker Death Marks by killing different Bosses. Should the Stalker make his appearance and be slain, the Death Marks do not disappear all at once, meaning players will encounter him again on different missions.
• Players are unable to abort the Mission while the Stalker is present.
• If Protector Stalker spawns in a mission, while one of the squadmates is playing as Jade, he will refuse to fight, dropping his loot and simply fleeing a few seconds after spawning instead.

Trivia

• Digital Extremes staff has been known to occasionally "hijack" the AI Stalker as a player character under their control. A more refined version of this "Stalker Mode" was presented during TennoCon, where selected players were allowed to hunt down others and has since returned from time to time during Prime Time streams.
• His internal name (in the game files) is simply "Assassin".
• Apart from his unique helmet, his Excalibur body is also (now) somewhat unique, as he still uses an older version of Excalibur (which is also still used by Nyx) before he received a slight overhaul to his textures and color channels, most noticeably at the outer arm pieces and the cables on his neck sides which are more of a shiny grey whereas the updated Excalibur textures have them of a darker, matted color.
• Before Update 36.0 (2024-06-18), Stalker was voiced by WARFRAME's audio director George Spanos, who also voiced with Lieutenant Lech Kril. After Update 36.0 (2024-06-18), Stalker has been redubbed by Gianni Matragrano.
  • Stalker's ability to speak from single words to full sentences (during taunts) contradicts Loid's statement that Warframes can only scream, roar or howl as the Orokin dictated so, making him the only Warframe capable of doing so.
• The Stalker's favorite breakfast food is "sugar crisps" according to [DE]Steve as jokingly stated on Prime Time #190.
• Before Update 18.0 (2015-12-03), the Stalker communicated with the Tenno with indecipherable whispers.

• This taunt is actually played in reverse. The actual message heard is a long, drawn out message that simply and repeatedly says "Death" at varying speeds.

• The voice lines are still used for the Acolytes.

• The Stalker has his own theme when encountered:

Bugs

• If the Stalker spawns in the Orokin Derelict and there happens to be a lot of infested in the room and the room happens to be really big, when the target player moves far enough away from the Stalker he will forget about the player and start targeting infested instead. He will attack his target if it comes back into range or most infested have been killed.
• Having  Guardian equipped on your sentinel will allow his Dread to deal no health damage if the damage were to surpass your shield limit. This only happens when the Guardian is not on cooldown.
• When the Stalker is killed during a mission, the mission complete music is replaced with the Stalker theme. The same thing happens to the defense music, you will continually hear the Stalker music during the wave. After finishing the mission, it will return to normal music.
• The Stalker may sometimes cast Absorb as soon as he is defeated. This will cause him to immediately disappear right as he finishes his ability. (The damage from Absorb will still trigger).
• Sometimes, the Stalker may say that the player has killed a boss other than the most recent one killed (ex.The Stalker may state that the player has killed Lech Kril, despite the player not even having Kril's system unlocked).
• The Stalker will sometimes taunt and attack players below Warframe rank 5 though this occurrence is extremely rare unless the player is in a lobby with another player who has the deathmark.
