Deimos emerges in Martian orbit, completely overrun by the Infestation... yet among the writhing mass, a distress call comes over a most ancient carrier wave...

—In-game description

Heart of Deimos is an optional solo-only quest released in Update 29.0, introducing the Cambion Drift Landscape that has been overrun by the Infested and the Entrati Orokin family that seeks to maintain the Heart of Deimos. Completing this quest awards the blueprint for XakuIcon272.png Xaku.

Synopsis[edit | edit source]

Walkthrough[edit | edit source]

After completing the Earth to Mars Junction, the player will receive an inbox message from Loid, a Cephalon servant to the Entrati, requesting the Tenno's assistance on Cambion Drift, Deimos. The quest can then be initiated in the Codex.

Visit Cambion Drift[edit | edit source]

As soon as the Tenno land on Cambion Drift, they are greeted by Loid, the sender of the distress signal, and Otak, another Cephalon that shares the same body with Loid. Loid explains that the Infestation's Grey Strain has overrun Deimos, threatening to compromise its very Heart. For the Tenno to enter the Necralisk and meet with Mother, they are required to prove themselves.

The player is directed to destroy two nearby Infested Hives. Damaging a hive will spawn Infested, all of which must be exterminated before the hive can be destroyed. After destroying both hives, Loid allows the Tenno to enter the Necralisk.

There, the Tenno meet the Entrati, an Orokin family that researched the Void, now all partly Infested. Mother explains that the Heart is her father's family legacy that "pumps the arteries" from the Void to power Orokin devices, including Warframes. The only one who knows how to fix the Heart is Father, who had left the family.

Locate Father Within the Cambion Drift[edit | edit source]

Returning to the Cambion Drift, the Tenno encounter a Necramech, an Entrati combat platform, which Loid believes to belong to Father. The Necramech is already in combat with the Infested, making one final stand before eventually bleeding out and dying.

After the Necramech dies, the Tenno must search the area for Father. He applauds their combat readiness, but due to his estranged relationship with Mother he does not believe the Heart is breaking down and adamantly refuses to help. Loid suggests the Tenno head back to the Necralisk to speak with Daughter.

Back at the Necralisk, Daughter agrees to help if they assist her in return.

The Exocrine Expedition[edit | edit source]

The player must have a Fishing Spear in their Gear loadout before proceeding.

Daughter wants to rebuild her sample collection that her brother destroyed. Shortly after entering the Cambion Drift, the Tenno are introduced to Fass, the orange wyrm that appears in the background. His twin sister, the blue wyrm Vome, rises in the opposite end and fires a laser that destroys Fass, causing Fass Residue to litter the Cambion Drift. Daughter explains that Fass will eventually regenerate and exact revenge, repeating the cycle.

The Tenno must collect at least 10 Fass Residue. The impact zone of Fass's remains creates some minor static distortions in the HUD. The Residue act like Fishing Bait; the fishes in the Cambion Drift swim out of the exocrine and float around in the air, however the player's own fishing spear cannot penetrate the viscous surfaces of the exocrine. The Tenno must fish for 3 specimen before returning to the Necralisk.

A group of Infested lie in wait to ambush the Tenno outside the Necralisk; Loid refuses to open the doors until they are exterminated.

Daughter warns the Tenno to be wary of Son when they venture to the Heart.

Descent to the Heart[edit | edit source]

Just outside of the Necralisk is an Esophage that will take the Tenno to the cave system that contains the Heart. Along the way, they meet Son, the disowned Entrati member who unleashed the Grey Strain on Deimos in attempt to gain attention from his parents.

The door guarding the Heart contains a Requiem Cipher, locked by four Requiem symbols on its panel. The player is only given a brief moment to memorize the pattern before interacting with the nearby Reactive Crystals, in the order of the symbols from top to bottom. As the Tenno approach the Heart, it releases a pulse that abruptly disables the player's Warframe. A rogue Necramech emerges from the Void door and opens fire on them before destroying the Heart.

Without the Heart, the Warframe has lost most of its power and remains barely functional: the HUD is covered in static, their shields are depleted and their health severely reduced, all of their weapons are disabled, and they can no longer able to use their abilities, as well as slide and bullet jump. The player must return to the surface while carefully avoiding the patrolling Necramechs, although they will immediately respawn if killed making it impossible to fail. Once they return to the surface, they must take the Esophage back to the Necralisk.

The Entrati family realizes they need to unite to restore the Heart. Father has something to prepare for the Tenno's descent: a Voidrig Necramech, dubbed Snake.

Through, and Beyond[edit | edit source]

Father proceeds to guide the Tenno through their first Necramech control, but Mother insists they don't have time and they'll just have to learn as they go.

  • The Voidrig Necramech has 1,000 shields and 3,000 health.
  • The Mausolon.png Mausolon is a fully automatic Arch-gun with 300 rounds, and recharges when not in use. It possesses an Alternate Fire that can be used after 5 primary fire kills, charging a destructive explosive laser.
  • The Necramech's melee is a slow arm swipe that does moderate damage and knocks back enemies.
  • The Necramech can use its engine thrusters to charge forward instead of rolling, and can hover. Both actions, along with sprinting, use the Engine Gauge, which slowly replenishes when not in use.
  • The Necramech has three abilities that gradually unlock as the player progresses the mission.
    • The first ability, Necraweb, deploys a canister that can be thrown with Alternate Fire, creating a large explosion when shot out of the air.
    • The second ability, Storm Shroud, provides an electrical armor that grants a brief invulnerability period and converts any taken damage to increase the Necramech's armor similar to IronSkin130xDark.png Iron Skin, and reflects damage to enemies striking it.
    • The third ability, Gravemines, launches a cluster of mines around the Necramech that explode when touched.
  • The player will respawn if they die, making it impossible to fail the mission.

Waves of Infested will attempt to impede the Tenno's progress as they reach the Heart, including three Infested Hives. After destroying all hives, the five panels on the ground will light up and float when stood on, and the Necramech will auto-equip an Omni to patch the fires surrounding the Heart.

With the Heart patched, Mother successfully restarts the Heart, but the enemy Necramech reemerges from the opened Void. The enemy Necramech is only vulnerable to its shoulder joints, its skull-like face plating, and the blue Void scar on its back, with the former blasting off its arms and removing its ability to use guns and melee. After the enemy Necramech is defeated, the Tenno's Necramech will exhaust itself and collapse. With the job completed, they are sent back to their Warframe.

Epilogue[edit | edit source]

Back in the Necralisk, the Tenno meet Grandmother, who notes that the Entrati, despite its dysfunctional family members, will come together in a crisis. The Tenno glean from the conversation that Grandmother caused the events surrounding the Heart's destruction to unite the family. She awards the Tenno the blueprint for the XakuIcon272.png Xaku Warframe, a "family of themselves", and the Deimos Necralisk Captura Scene.

The Entrati syndicates is now available, with Mother offering Bounties, Father selling unique weapons, Daughter with fishing, Son with wildlife conservation, Otak with mining, and Grandmother with standing transaction and selling unique Captura Scenes and Orbiter Decorations.

The Necraloid syndicate will also be available if the player has also completed The War Within.

Notes[edit | edit source]

  • Players who already have a fully built XakuIcon272.png Xaku prior to completion of this quest will additionally receive a Riven Mod.

Trivia[edit | edit source]

  • Father's Necramech named Snake, along with shouting "Snake? SNAAAAAAKE!!!!" if the player dies in the Necramech, is a reference to the Metal Gear Solid series, in which the protagonist is named Snake and the mission control characters shouting similar lines during a Game Over when Snake dies.
  • In the cutscenes with the enemy Necramech, it is shown wielding a Cortege.png Cortege, and at one point fires Mausolon.png Mausolon-like full-auto rounds. However, when fought it is armed with a Mausolon instead.
