I was the Stalker, crouched under cold metal while two names closed in and the ship smelled of ozone. You can feel your options thin to a single seam: wait for a charge and strike. By the time the scene ends, you’ve already learned who you are chasing.
If you want the straight path: you need The New War and the original Jade Shadows quest active. I’ll walk you through each beat — from the opening ambush to the home-cooked finale — and point out where to hold your breath and where to hit hard.
A stopwatch on your desk reads “40:00” — what the run feels like and the opening ambush
The quest runs about 40 minutes if you watch the cutscenes and take the scripted beats seriously. I started the sequence already inside the Stalker’s shoes: two hunters—Sirius and Orion—spring the trap. Their names change on your screen, but their behavior is identical.

They charge, freeze for a brief second, and open the window you need. I leaned into that pause: let them commit, then unload. Shooting them head-on early makes the fight drag; patience wins. Your Stalker kit rewards burst windows — Smoke Screen is one of those windows.
How long is Jade Shadows: Constellations?
Plan for about 40 minutes with cinematics. If you speed-run combat sections you’ll shave time, but story beats and the mini-game take a fixed chunk.
A blinking console will ask for attention — Tenno ship, Ordis and the Umbra match
Back on your ship, Ordis becomes the distraction. I told you to move left and trigger the marker — you’ll hide, pull the bait, and then follow the path that places you against Excalibur Umbra.

The next objective is a multi-point capture battle that works like The Index. Hold capture points until the meter flips your way. I used the Stalker’s Smoke Screen to disappear from Umbra’s sensors and take objectives quietly — it’s a legal way to force favorable resets.
A corridor lined with traps tells you how the fight will play out — entering Ryoku’s ship
Inside Ryoku’s ship you’ll meet clones and traps meant to annoy you. They slow you down but don’t outclass you. I moved through them as a cleaner moves through clutter: swift and indifferent.

Ryoku’s dash is the danger here. Don’t trade hits; bait the dash, then vanish. I hit Smoke Screen and punished him while he scrambled to find me. The ship’s traps are a nuisance but manageable; target the boss and ignore decoys when possible.
How do I beat Ryoku and Vena?
Ryoku: Force his dash, then use Smoke Screen to break tracking and land heavy damage during his recovery. Vena: clear her blood-bind sources first, keep distance to avoid vines, and pressure her while she tries to recharge shields. Headshots hurt Jade Mockery most, so aim high in that final exchange.

A cluster of red tendrils is a clear warning — defeating Vena and Jade Mockery
To reach Vena you must switch off three terminals. Each terminal is protected by a blood bind; trace the bind back to its source and destroy it before deactivating the terminal. That sequence cuts the fight into manageable chunks.

Once Vena is down, a void anchor summons Jade Mockery. She hits hard but predictably — aim for her head to cut the encounter short. I found this boss the easiest of the three when I stayed mobile and timed my bursts to her shield cycles.

A small pair of hands on a shoulder changes the tone — Umbra, the child, and the distraction
Umbra sits with the kid while you issue commands. The minigame that follows is narrative weight more than mechanical test — I let Umbra soothe the child while I handled the prototype fights. The outcome of that minigame doesn’t change the path forward.
While Umbra manages the child, you pick one prototype to strike first. I chose Ryoku; you can choose Vena. Either route folds back to the same sequence: come back to Hunhow, explain what you saw, then move to the final encounters.

What are the correct food recipes for Sirius and Orion?
Serve Orion: spice + vegetable. Serve Sirius: sugar + meat. Those combinations satisfy the scene and close the quest.
A map pin glows on Uranus — rewards, Railjack access and where to farm next
Finishing the quest drops blueprints for the main Sirius and Orion item and opens the Uranus Proxima node for new Railjack missions. If you use tools like the Warframe Market or DE forums, you can compare parts and plan a build for Railjack sorties.
I mention Digital Extremes because they designed these beats; the quest plays the same whether you’re on PC (Steam), PlayStation, or Xbox. If you like story-led rewards and small, intense combat loops, this route delivers.
I’ve told you how to handle each fight and where to hold patience. The fights pause like a stopped clock, and the child clings to Umbra like a moth to a lantern — which moment will stay with you after you finish?
