The Promethean Code
From Destinypedia, the Destiny wiki
The Promethean Code is the sixth story mission in Destiny The Taken King. It takes place in the Cosmodrome Old Russia and the Guardian's objective is to steal stealth tech from the Warmind Rasputin.
The Guardian mounts their Sparrow and heads into the Forgotten Shore, reaching Rasputin's bunker underneath.
Upon reaching the bunker, the doors open for the Guardian. Telltale signs of blight residue are scattered throughout, an obvious warning:
Larger spots and portals are seen as they head in deeper.
Taken appear within the Seraphim Vault, attacking the Guardian. They eliminate the deformed Thrall, Vandals and Captains. Heading towards the control room where they previously encountered Omnigul, they find the doors locked.
The Guardian turns back and reaches a previously unopened door. Venturing through it, the Guardian finds themselves exploring even further within the Bunker. They come across more Taken blights, and forces stemming from them. After destroying all of them, the Guardian finds a massive room behind a pane of glass. Curious, the Guardian finds a downed computer station and sends the Ghost to scan it:
The Guardian moves on, into a nearby hallway.
As the Guardian enters another large room, Taken spawn between them and the next door. The Guardian eliminates them and continues. A red computer monitor grabs the Ghost's attention:
The Guardian moves on, finding a long narrow hallway. Taken defenses start to thicken; the Guardian is close. They reach an area with a staircase, and a small door at the other end. A strange piece of machinery sits near the door. After killing the Taken presence there, the Ghost scans it:
The Guardian goes through the door and continues down the hallway. They reach a dead end; Rasputin's main computer room. However, Taken Centurions and Psions appear inside. The Guardian disposes of them and is left in peace.
The Guardian sends their Ghost to the monitors.
Alternatively, if the Guardian is attempting this mission on the Heroic difficulty, the mission will continue from the Ghost's scan:
Suddenly, the panel the Guardian is standing on dislodges from the floor with a hydraulic hiss; the panel is a secret elevator. It leads the Guardian further below.
The elevator stops, reaching what appears to be a basement. Two ledges sit on either side of the walls. A second door opens up from the other end, and a Bracus steps out of it, followed by Taken infantry.
The Guardian kills the Taken enemies and receives a strange object, the Essence of the Feast.
