Rogue Trader The Siege Walkthrough

Head to Eufrates II on the Emperor's Palm system. You will have the option to begin by holding a war council. All companions will be present, as well as Opticon-22, Thorbald Ironhide from the Space Wolves and Aishara (an acolyte of Calcazar). Opticon-22 and Thorbald Ironhide will be butting heads but you can make them reconcile with a Lore (Imperium), Logic or Persuasion test. Finally you will be asked to choose a strategy. The strategy does not affect the gameplay but decides the narration of the assault. All strategies are equally viable but reconciling Opticon-22 and Thorbald Ironhide will prevent the former's death/

1. "Send in all our forces even if it means sustaining heavy losses. A swift onslaught is key to our victory!"
2. "We will begin by bombarding the enemy's positions, then advance cautiously. We must conserve our troops."
3. "What we require is total annihilation. Raze every sacred facility and chapel that our enemies could use as cover."

If Ulfar hasn't been permanently removed from the party you will get the The Baleful Howl quest.

Go to Eufrates II and try to land. You will begin void combat against a Blasphemous Styx-Class Heavy Cruiser. After the fight try to land again and you will receive a book event detailing the battle. Every stage will have a skill test. Heretical and Dogmatic characters will be able to skip one skill test. If you pass 3 skill tests the assault will be a success and some cultists will surrender in the coming battles. The final stage will have the following two options:

1. "...gave his/her blessing to Opticon-22 and his suicide mission." - Opticon-22 dies
2. [Weapon Skill] "...led his/her retinue to hunt down this ancient killing machine himself/herself." - Opticon-22 survives and gain Unhallowed Bellow

You will land on the planet, where you will encounter Uralon the Cruel and Kunrad Voigtvir again before the Space Wolves begin fighting them. You will start in an area with multiple lockers you can loot. Proceed until you will encounter a group of corrupted skitarii. If you succeeded in the planetary assault they will surrender and you can either execute them or merely demand their weapons.

Now you can go in two directions. The exit is on the right path but going directly will ultimately lead you to some enemies and one of the most difficult boss fights in the game. It is recommended to go left first because there is a way to either make the fight easier or avoid it.

The left side of the map has a couple of traps and multiple loot areas. There is also an optional boss fight against a Voracious Pink Horror. Explore the left side thoroughly and you will encounter an elevator. Use it to go to the lower levels. There are no enemies on this side but there are multiple traps. You will also need to pass a Tech-use test to extend a bridge. Eventually you will come across a Wandering Psyker but your dialogue choices do not matter and she will die at the end. You will next need to pass an Athletics test to jump over a gap, as well as blow a hole in a wall with a Melta Charge. Immediately afterwards there is a hidden door on the right that you can uncover with sufficient Awareness. It will unlock a room with a chest. Head back into the plasma generators room and you will fight a group of heretics. Loot everyone, including a locked crate you can find. There is also an optional Lore (Imperium) test. Walk past the door, interact with the Corrupted Cogitator, and if you have sufficient Lore (Warp) you can remove a warp barrier. Before the elevator you can also find a tiny hidden safe on one of the walls if you have sufficient Awareness. When ready, take the elevator up.

Once you're back on the main map you can do two things. You can go immediately left to avoid the boss fight. Alternatively you can open the cages with the enslaved psykers, who will damage some enemies and destroy one of the generators and weaken the coming boss. Then you will face Incongruous Defiler. The boss is powered by 4 plasma batteries, or three if you started the fight by releasing the enslaved psykers. Destroying the batteries will weaken it but if they are destroyed in melee they will stun all adjacent characters. Every round the Incongruous Defiler will target two areas on the map with Havoc Barrage. You need to get out of the targeted areas until the boss' next turn as the attack deals heavy damage and sets fire to the attacked tiles. After every character's turn the Incongruous Defiler will fire a missile but it is generally easy to dodge it. Once you defeat it, the boss will restore its full health and fight once again. After the fight loot the rest on the map and proceed to the next map.

From the beginning of the next map you will notice there are two ways which you can go: forward and left. The forward path has a warp barrier you can remove. It loops back into the left path and contains an optional fight. Before the right you can pass a Logic test on a cogitator in front of the fighting area to kill or damage a few enemies. After the fight check one of the corners in the room. If you have sufficient Awareness you will uncover a hidden door leading to a storage room with two crates and a large locked safe that contains Triumph of the Stalwart.

Shortly after leaving the starting area, warp barriers will appear all over the next area. Those barriers cannot be removed so more very carefully around them to avoid traumas. There are two doors to exit the area but the lower door can only be opened from the other side. The northmost section of the map contains Doomscream. If you have the The Baleful Howl quest you will need to defeat Doomscream to complete it. If you don't have the quest you fill find both the Space Wolves and Doomscream dead. When you are ready, follow the eastern corridor until you reach a door.

You will finally reach Uralon the Cruel and Kunrad Voigtvir, who just finished defeating the Space Wolves. If you have completed all objectives in the The Call of the Edge quest you will have a dialogue option to tell him a keyword given by Edge of Daybreak and side with him.

• If you did not side with Uralon the Cruel you will fight him and Kunrad. Uralon can summon daemons and can grant one of his allies a turn. Kunrad will cast lightning to their targets and uses a melee weapon to attack but is easy to defeat.
• If you sided with Uralon the Cruel you will fight Thorbald Ironhide and the Space Wolves.

After the fight Kunrad will be sacrificed to summon Edge of Daybreak. If you sided with Uralon the Cruel you can choose to swear fealty to Edge of Daybreak or fight it. Otherwise you will always fight it. Edge of Daybreak has the ability to summon 1 Herald of Tzeentch and 4 Pink Horror, which it will use every few turns. The battle will begin at half Veil Degradation and Edge of Daybreak will max it.

After the battle loot everyone. You can also find an optional Lore (Warp) on the chaos altar. When you're done, interact with one of the two cogitators in the center of the map and report Uralon's death. In the post-fight conversation you will speak with a dying tech-priest and find out more about Calcazar's intentions. There will also be two optional Tech-Use tests in the conversation.
