Update Overview

What's New in Update 43

Warframe Update 43, titled Jade Shadows: Constellations, is a landmark mainline release that expands the Jade Shadows narrative while introducing a fundamentally new Warframe archetype. Where previous updates added single frames with four abilities, Constellations delivers Sirius and Orion, two brothers who share one loadout slot and swap mid-mission through a dedicated dual-control system. The update also opens Uranus Proxima, a Railjack region tied to the questline, and establishes Pontis Tower as a persistent social hub with vendor exchanges, fast travel, and mission staging.

Beyond the headline content, Update 43 refreshes long-standing systems. Nidus receives a comprehensive ability rework that modernizes his stacking mechanics and team utility. Styanax Prime arrives alongside the update as a Prime Access rotation, giving collectors a timely boost to shield-based builds. Five weapons gain Incarnon Genesis evolutions, and four new Arcane Enhancements drop exclusively from Uranus Proxima content. Together these pieces form one of the densest patches in recent Warframe history, bridging story, endgame farming, and quality-of-life improvements in a single download.

Constellations assumes you have lived through the broader Jade Shadows arc. The update does not re-explain every prior betrayal or alliance; instead it pushes the story toward Hunhow's escalating influence and the brothers' fractured loyalty. Gameplay systems introduced here persist beyond the quest: Uranus Proxima remains on the star chart, Pontis Tower stays populated with vendors, and dual-Warframe rules apply anywhere you equip Sirius and Orion. That permanence makes this overview essential reading before you commit mod resources or forma.

Sirius and Orion: The Dual Warframe

Sirius and Orion represent the first true dual-Warframe design in the game's history. Players install both brothers into a single slot; in mission, you control one brother while the other remains accessible through swap mechanics tied to ability inputs and a dedicated swap action. Each brother has a distinct ability set themed around celestial constellations, with abilities that generate and consume Constellation Stars used to fuel their shared ultimate, Celestial Clash.

Sirius leans toward supportive and control-oriented play, with abilities that manipulate enemy positioning and apply debuffs. Orion emphasizes direct damage and burst windows, rewarding players who chain ability casts and maintain star generation. The design encourages alternating between brothers rather than staying on one for an entire mission, because star colors and ability synergies change depending on which brother initiated the last cast. Mastery Rank requirements follow standard Warframe acquisition: blueprint from the quest, component parts from Uranus Proxima, and signature weapons Pride and Wrath tied to Emerald and Crimson Talent economies respectively.

For players coming from traditional frames, the learning curve is real but manageable. The update ships with a mandatory quest segment that teaches swap timing, star matching for Celestial Clash, and the difference between tap and hold ability inputs. Once learned, dual swapping feels comparable to managing Helminth subs or Operator mode transitions, except it happens every few seconds in combat rather than as a separate mode. Helminth rules treat the pair as one installed frame for subs, with additional restrictions documented on the Controls section of this wiki.

Build diversity emerges from constellation star colors. Abilities tagged with matching colors contribute to Celestial Clash damage multipliers, while mismatched colors still provide utility but reduce ultimate burst. Competitive players experiment with duration versus range configurations per brother, often polarizing different slots because Sirius benefits from range for crowd control and Orion from strength for burst windows. Aura mods and exalted weapon interactions follow normal Warframe rules; neither brother introduces a permanent exalted weapon, keeping loadouts flexible.

Uranus Proxima and Pontis Tower

Uranus Proxima is the update's primary endgame farming region, accessible after progressing the Constellations quest. It sits on the Railjack star chart as a Proxima node cluster orbiting Uranus, with mission types including Skirmish, Volatile, and Aid missions featuring unique boss encounters. Unlike earlier Railjack regions that felt optional for non-Railjack players, Uranus Proxima is tightly integrated: quest objectives send you here repeatedly, and component farming assumes repeated runs.

Pontis Tower serves as the region hub—a tower structure floating in Uranus orbit where players meet Hunhow's vendor, access the Railjack configuration terminal, and queue for personal Railjack missions without needing a clan dojo. Fast travel links connect Pontis Tower to key mission nodes, reducing the friction of launching Railjack content solo. The hub also contains environmental storytelling elements tied to the Jade Shadows arc, including interactable lore fragments and a codex terminal that unlocks after quest milestones.

Players without a personal Railjack can still complete all Uranus Proxima content using loaner ships provided during Aid missions or by launching personal Railjack missions from the star chart interface, which spawns a temporary solo instance with default ship stats. This accessibility choice matters because the update's farming loop otherwise risks gating new players behind Archwing and Railjack research. See the Railjack beginner guide on this wiki for step-by-step personal mission launches.

Mission rewards split across Crimson and Emerald Talent tokens, Arcane drops, and component blueprints. Aid missions Scoria's Angel and The Kuva Wytch anchor the boss farming routes for Vena and Ryoku respectively, while Skirmish and Volatile nodes feed general token income. Steel Path variants unlock after standard completion, mirroring other Proxima regions but with Railjack-specific modifiers introduced in Update 43.

Nidus Rework

Nidus receives ability changes across his entire kit in Update 43. Larva now scales its pull radius with Mutation stacks and applies a brief ragdoll on enemies caught at maximum stacks. Undying retains its core immortality loop but grants energy regeneration when Nidus revives from death, addressing historical energy starvation during high-level content. Parasitic Link splits behavior: allies linked gain increased ability strength, while enemies linked take amplified damage from Nidus abilities and contribute Mutation stacks on death.

Ravenous maggots explode into healing zones that scale with the number of active maggots consumed, and viral spread synergies refresh stack timers more reliably. The rework positions Nidus as both a solo Steel Path candidate and a supportive anchor for star-generation teams that want a tank with crowd control. Existing Nidus mains should revisit mod configurations: range and duration tradeoffs shifted because Larva's pull now rewards higher range more consistently than before.

Mutation stack cap interactions with new content were tested heavily during public test server cycles. Stacks persist through cutscenes in quest instances but reset on extraction in open world zones per standard rules. Nidus players joining Sirius and Orion teams often serve as the stable front line while dual swaps happen behind Larva walls.

Styanax Prime

Styanax Prime launches alongside Update 43 as part of Prime Access. The Prime variant increases shield capacity and ability strength compared to the base frame, with cosmetic differences on helm, chassis, and systems. His signature Prime weapon bundle rotates separately from the main update content, but the timing aligns with Constellations marketing so new and returning players encounter shield-based gameplay loops while learning Sirius and Orion.

Styanax Prime does not gate any Constellations quest content; he is optional power for collectors. Players evaluating Prime Access should weigh whether shield-tank builds complement their existing roster, especially if they plan heavy Steel Path Railjack where shield gates and ability strength matter on pilots and crew. Relics for Styanax Prime components enter the drop tables immediately at launch without displacing Uranus Proxima rewards.

New Incarnon Genesis Weapons

Five weapons receive Incarnon Genesis adapters in Update 43, extending the Incarnon evolution system introduced in earlier updates. Incarnon modes typically alter fire behavior, add elemental procs, or change projectile physics when toggled mid-mission.

Weapon	Class	Incarnon Theme	Notable Evolution Perk
Braton Vandal	Rifle	Constellation burst fire	Increased crit on evolved mode headshots
Strun Wraith	Shotgun	Spread compression	Tighter pellet cone in Incarnon form
Gammacor	Beam pistol	Chain discharge	Secondary targets take partial beam damage
Magistar	Melee	Impact shockwave	Heavy attack emits radial stagger
Dread	Bow	Piercing arrow	Evolved shots pass through two additional targets

Incarnon adapters drop from existing Incarnon sources plus select Uranus Proxima rewards. Players who already completed earlier Incarnon farming can integrate these weapons into existing rotation routes without starting a separate grind track. Dual-mode weapons pair well with Orion's burst windows because Incarnon activation counts as a mode shift for certain arcanes.

Arcane Enhancements

Four new Arcanes debut in Uranus Proxima, three tied to Railjack roles and one general-purpose Warframe enhancement. Arcanes drop from boss missions, cache rotations, and token exchange pity thresholds.

Arcane	Category	Effect Summary	Primary Drop Source
Arcane Sculptor	Warframe	Ability casts grant brief armor scaling	Uranus Proxima Volatile
Primary Compression	Primary	Reload speed and magazine efficiency on kill streaks	Aid: Scoria's Angel
Secondary Surge	Secondary	Secondary headshots restore partial ammo	Skirmish caches
Engineering Flux	Railjack	Forge cooldown reduction for crew	Aid: The Kuva Wytch

Arcane drop rates follow the standard rarity tiers used in other Proxima regions. Steel Path variants increase drop chance and introduce arcane rank progression identical to existing Steel Path bonus rules introduced in this patch. Farming guides on this wiki break down expected runs per rank.

Update 43 at a Glance

Update 43 is best understood as three overlapping loops: finish the Constellations quest to unlock Sirius and Orion, run Uranus Proxima for parts and arcanes, and revisit older content affected by junction boss updates and Railjack Steel Path modifiers. Players returning after the New War and Jade Shadows quests will find a direct path forward; brand-new players still face the full prerequisite chain but gain clearer codex guidance than prior expansions provided.

Whether you care about story, collecting, or min-maxing Railjack, Constellations justifies the mainline label with breadth.
