Mass Effect 2 Lair of the Shadow Broker Guide (2026)

“Lair of the Shadow Broker” is one of Mass Effect 2’s most ambitious DLC missions, sending Commander Shepard into a tight web of Illium intrigue, hotel chaos, shipboard combat, and a final confrontation that’s as much about timing and positioning as it is about firepower. This walkthrough-style checklist breaks down every major beat in order, from accessing the DLC and planning your squad, to the exact investigation steps, combat wave patterns, Morality Point choices, and the post-mission conversation with Liara.

Release & platform access: editions and how to start

The original release of Lair of the Shadow Broker required installing the Cerberus Network service for Mass Effect 2, and the mission itself was offered free. With the Bioware website deactivated, the Cerberus Network access code must be handled through your EA account.

If you’re playing the Legendary Edition, or running the original version through Steam or PlayStation 3, the DLC is included with the game and installs automatically.

Before you begin: difficulty, timing, and why it’s worth it

Lair of the Shadow Broker is treated as an end-game mission. While you can start it immediately after completing “Horizon,” expect it to feel rough—especially on higher difficulty settings. The payoff is substantial, though: you can earn 90,000 credits from completing it, and many Research upgrades unlock afterward.

Travel to Illium

Prerequisite: Complete “Illium: Liara”
Location: Crescent Nebula – Tasale – Illium – Liara’s Office

After finishing “Horizon,” check your Private Terminal for a message from Cerberus Information Processing containing Shadow Broker Intel, instructing you to deliver it to Liara personally. Then head to the Crescent Nebula and land on Illium, the second planet in the Tasale system.

If you haven’t already, you can also mine these Rich worlds for resources.

Recommended loadout

Even though this part isn’t squad-focused, the guide notes a romance-related detail: if you didn’t romance anyone in Mass Effect 1, you’ll see alternate dialogue at the end of this mission if you delay the DLC until after you’ve locked in a romance.

Squad tactics:
- You’ll be paired with a new, mandatory squadmate, meaning most of the DLC’s combat involves only one of your two Normandy squad options.
- Garrus or Kasumi are recommended because of Overload.
- Miranda or Thane are recommended because their Warp pairs well with Singularity.
Unique dialogue:
- Garrus is especially useful for the post-Illium portion, since it unlocks additional unique dialogue in Mass Effect 3.

You’ll be paired with a new, mandatory squadmate, so plan for most fights to involve only one of your two Normandy squad choices.
Garrus or Kasumi are good picks due to Overload.
Miranda or Thane are good picks due to Warp, which works well with Singularity.
Garrus can add more unique Mass Effect 3 dialogue during the post-Illium segment.

Speak to Liara

Liara is in her office. The guide says it’s up the stairs marked “Administration,” to the right of the door that connects from the Trading Floor area to transportation and shipping.

System hacking? Observer?

Starting Lair of the Shadow Broker causes Liara to permanently leave her office. That means her two Illium Assignment side quests can’t be completed afterward here. Make sure you finish “Illium: Liara: System Hacking” and “Illium: Liara: The Observer” before launching the DLC.

Illium: Liara: System Hacking
Illium: Liara: The Observer

Talk to Liara and choose “Let’s get the Shadow Broker.” This triggers Liara’s departure, matching the warning above. If you didn’t already ask about “Anger at Shadow Broker,” you’ll get chances to earn Morality points.

Choose “You saved me” for +2 Paragon Points.
Choose “Why give me to Cerberus?” for +2 Renegade Points.

Take Cab to Liara’s

After speaking with Liara, go to the Taxi Stand at the southern-most point of Illium and select “Liara’s Apartment” to keep moving. You’ll be prompted to pick a squad; however, only one squad member will join Shepard early in the mission. Use the Recommended Squad advice above to decide who to bring.

Investigate scene

Once you arrive, you’ll talk with Tela Vasir. You can request as much information as you want, but the two of you still need to investigate the apartment to move the mystery forward.

There are multiple things you can Examine, but only one item on the second floor actually advances the plot. The guide recommends saving that key examine for last, while using the first floor for optional-but-interesting checks.

Shot Impact: On the first-floor window straight ahead after the cutscene.
N7 Armor: In a display case to the right of the Shot Impact window.
Painting: On the wall that’s lit white to the left of the apartment entry, across from the kitchen.
Tela Vasir: You can get five comments by finding her to the left of the stairs leading to the second floor.
Degree Certificate: Past Tela Vasir, on the right-hand wall behind the stairs.

After searching the first floor, head upstairs and Examine the Picture on the nightstand to advance the investigation.

Check Prothean relics

The guide says Liara left a clue behind before fleeing her apartment. To find the next hint, you’ll need to return to the first floor and examine Prothean material again. There’s a Prothean Relic near the apartment entrance if you want it, but the one that matters is in the display case at the base of the stairs.

Examining it points you toward the Dracon Center in Baria Frontiers. You can also earn Morality points here:

Choose “She’s in danger” for +2 Paragon Points.
Choose “So she did find something” for +2 Renegade Points.

Find Baria Frontiers

This leads you to the Dracon Trade Center somewhere else on Illium. The building explodes as you get close, driven by terror of Shepard’s presence. If you want, you can talk to the injured person outside, then move inside.

When you interact with the elevator on the far left wall, it’s down—so the only route forward is up the stairs on the opposite side.

At the bottom of the stairs, you’ll find a dead Employee to examine, plus:

Locker: 3,750 credits. To the right of the dead Employee at the base of the stairs.
Medical Station: 100 credits. Up the first set of steps and left around the corner.

On the second floor, you may spot a human sliding down a wall near the white-lit stairs. He dies while trying to speak to you. Examine the now-Dead Employee for a brief exchange with Vasir, then look around for the loot below:

PDA: 2,500 credits. From the white-lit stairs, look left to find a dead salarian holding this PDA, near a round door labeled “Nezo Transportation”.
Medical Station: 100 credits. On the left-hand wall of the white-lit stairs, above benches.
ATM: 6,500 credits. Hack the terminal on the stock market display at the top of the white-lit stairs.
Power Cells: 100 credits. From the ATM, turn right to find them near a round door labeled “Exsolar Shipping”.

To continue, head left from the ATM and go through the door labeled “Baria Frontiers.” Then use the Log Book on the left-hand wall to open the next area.

Search for Liara

After rounding the next corner, you’re ambushed by Shadow Broker Agents, including a flashbang. If that name sounds familiar, the guide compares it to the flashbangs from Kasumi’s Loyalty mission. Flashbangs disrupt vision and hearing if they detonate nearby, and a close-range blast staggers you away from cover.

The encounter is supported by tougher enemies—heavies plus shielded Engineers and Vanguards—making it a well-rounded fight. It’s also long: you move around a corner, past a fiery hole in the right-hand wall, then turn left and head back inside. You can shoot through glass.

When all enemies are dead (signaled by the music calming down), return to the office cubicles where you first got flashed and face forward. The room has loot.

Terminal: 3,000 credits. Go through the doorway on your left and check the cubicle closest to the left-hand wall to find the laptop terminal.
Terminal: 3,000 credits. Continue down the main path past the fiery hole in the right-hand wall. Enter the room with holograms; from there, head left to the far end, then turn left to spot a laptop on a desk beneath the window.
Medical Station: 100 credits. At the far end of the combat area is a cafeteria (also on fire). Check the back-right corner of the cafeteria for the Medical Station.

Once you reach the stairs, you must extinguish the fire before progressing. The guide suggests using a side room and the Maintenance Console to activate the fire suppression system (water sprinklers). There’s also loot in this side room:

1,000 Refined Element Zero: In the back-right corner of the side room containing the Maintenance Console.
Machinery: 1,500 credits. Salvage from the back-left corner of the same side room.

At the top of the stairs, you fight three more Shadow Broker Agents around a glass balcony above the earlier cafeteria. After shooting them, proceed through the next two rooms for the following loot:

Research Terminal: Heavy Pistol Damage. In the first room, on the console with holograms in the back-right corner.
Wall Safe: 5,000 credits. On the left-hand wall of the second room.

Pursuit

After the cutscene, you’re back on the second floor near the white-lit stairs and must chase Liara, who is chasing after her own assassin. The guide warns of two groups of particularly stubborn mercenaries; clear them, then head outside.

This turns into a chase above the streets of Illium. The guide compares it to Star Wars: Episode II—speeders, neon skyscrapers, and an assassination pursuit that should feel familiar.

The key is to keep your finger on the boost button at all times. The guide notes that crashing the taxi doesn’t cause much damage, and the real challenge is keeping Vasir in view. You aren’t meant to “catch” her; you’re trying to stay alive until a specific point triggers. Pitch adjustments aren’t something you need to micromanage, since the game handles it (often for dramatic effect).

Eventually Vasir crashes and you’re back on the ground—specifically, on hotel balconies.

Defeat Mercs

The instant you regain control, the guide makes the call: GO TO THE SQUAD SCREEN! Liara is now a squadmate, and fights ahead are tough, so distribute points quickly. She’s already loyal to Shepard and has access to Singularity, described as a unique power that stuns targets in its field of effect. The recommendation is to max it out right away, and to also max Asari Scientist (to reduce power cooldowns) and Stasis to Enhanced if possible.

Next, you fight multiple waves of Shadow Broker goons in the parking area outside Azure. This is difficult because fresh transports arrive with each wave, and their positions vary depending on where you are. The guide contrasts this with typical Mass Effect 2 fights where a strong defensive position can carry you—here, you’re repeatedly flanked.

Good news: the sixth wave is stopped by a car launching from the center of the battlefield, crashing into the left wall and killing everyone inside. The guide calls it both fortunate and hilarious.

Before leaving, grab:

Med Kit: 100 credits. Found in the back seat of the Rapid Transit taxi you arrived in. Useful during the fight if you need it.
Bank Terminal: 1,500 credits. At the front of the first truck that lands in front of the hotel’s main door.

Follow Liara

Continue through the hole in the wall where the final transport crashed, moving on after Vasir. Even though you could technically stay on the balcony, the guide points out there’s useful loot inside.

Med Kit: 100 credits. From the entrance, on shelves on the right-hand wall (not in the kitchen).
Wall Safe: 6,000 credits. On the kitchen’s back wall, immediately to the right when you enter.
Lustful Video: In the bedroom accessed through the doorway left of the Med-Kit. Interacting with it triggers an amusing exchange with Liara and you can also get a comment from the two cowering patrons in the room’s corner.

Exit through the other door to return to the balcony where Vasir’s flaming red car is.

Power Cells: 100 credits. Found in the back seat of Vasir’s Rapid Transit.
Vasir’s Car: Damage Protection. Interact with the circle-shaped object on the side of the Rapid Transit to gain Damage Protection.

From the Rapid Transit car, keep following the balcony clockwise until you reach pools of blood.

Follow Blood Trail

After discovering the blood pools, you cut through a hotel room where you can hear screaming—so, yes, loot time. Grab:

Med Kit: 100 credits. On shelves in the bedroom to the right of the entrance, beside a Weapon Locker.
Medical Station: 100 credits. On the side of a cupboard in the kitchen area.
Personal Datapad: 2,500 credits. On top of the coffee table in the corner of the main hotel room, visible from where the Medical Station is.

Move the blood pools toward the exit of the hotel room, where you face Vasir—along with a hostage. The guide says you can earn Morality points immediately:

Pick “Mariana, I’m here to help” for +2 Paragon Points.
Pick “Escaping won’t help you” for +2 Renegade Points.

Then you decide how to resolve the hostage situation. The guide stresses it doesn’t look as dangerous as it is: no option kills the hostage, and all choices grant comparable Morality points.

Pick the Charm option “I’ll shoot if I have to” to stall long enough for Liara to separate Vasir from her hostage, for +15 Paragon Points.
Pick the Intimidate option “You’re pathetic” to insult Vasir long enough for Liara to separate her from the hostage, for +15 Renegade Points.
Pick “[Drop thermal clips.]” to comply. Vasir throws the hostage to the ground for +15 Paragon Points. You start the boss fight with NO AMMO, so you’ll need to find more.
Pick “[Wound the hostage.]” to shoot Vasir through the hostage for +15 Renegade Points. Shepard also makes a Terminator 2 reference.

You then fight a Spectre. Vasir uses Shockwave and Charge, allowing her to teleport around while blasting through your cover. Drawing a clean target can be difficult, so don’t be surprised if squadmates deliver most of the damage. Keep moving, since Shockwave can strip health and shields fast, and maintain distance.

At intervals, Vasir teleports out and calls reinforcements. The first wave is two Engineers, which is manageable, but the second wave includes a heavy and a couple of flying turrets. The guide suggests bringing a squadmate with Area Overload to knock turrets out, since they’re hard to target.

Once Vasir falls, you get two separate chances to earn Morality points. The guide emphasizes these are not mutually exclusive because they happen on different dialogue wheels.

When Vasir justifies working with the Shadow Broker, pick “You crossed the line” for +2 Paragon Points.
When Vasir mentions Shepard working with Cerberus, pick “What they had to do” for +2 Renegade Points.

Next cutscene: Shepard regroups with Liara, who behaves like a new, distant version of herself. You’ll get three Paragon Interrupts. They don’t grant Morality points, but they matter for understanding why Liara is different now. The third interrupt is especially relevant if you romanced Liara in Mass Effect 1, since you can ask her about it directly.

Find entrance

You’ll choose your non-Liara squadmate again, and the guide notes your selection here can differ from the earlier Illium segment.

Miranda: One of the best picks, since she offers Warp to pair with Liara’s Singularity, plus Overload to strip shields.
Garrus: A good option if you want Mass Effect 3 unique dialogue, and he still fits this combat setup.

Navigation on the exterior hull of a ship during a storm isn’t intuitive, but the path is still essentially linear. The guide advises progressing either toward the ship’s front (identified by tall panels in the distance) or toward the center. Early on, you’ll mostly deal with basic maintenance drones.

Conductor Components: 3,000 credits. After the Maintenance Drones fight, head right and up a ramp toward the middle; watch for these under the left-hand railing of the ramp.

At the top of the ramp, you face your first agents encounter on the ship. The guide says there are two environmental advantages:

If an enemy is lifted high enough, high winds whisk them away—an instant kill that can be exploited with the right biotic powers.
The hull contains Lightning Capacitors. When bullets hit them, they discharge an electric blast that stuns and damages nearby targets, including you. The capacitors recharge after a few seconds.

The advice is to abuse both mechanics while crossing the ship.

After moving down the left side and killing some LOKI Mechs, you return upward for more Shadow Broker Agents. You’ll hit a blockage. Use the Rod Controls to the left of the Lightning Capacitor to clear the way forward.

Then you kill more Agents, go back a bit, and head to the right-hand side of the ship to fight additional LOKI Mechs. Loot here includes:

Conductor Components: 4,000 credits. During the second LOKI Mech fight, check the left-hand wall near a white light.

Continue down the ship’s side until you reach walkways on the far right. This area includes both Shadow Broker Agents and LOKI Mechs. After they’re dealt with, you briefly enter the ship for extra loot and some additional dialogue triggers:

Ship Engines: On the left-hand railing of the interior walkway.
Motion Dampeners: On the inside corner at the end of the interior walkway.
Power Cells: 100 credits. On the far corner of the interior walkway.
4,000 Refined Palladium: Sitting on top of the Power Cells.
Medical Station: 100 credits. Go back outside and take the left ramp; it’s on one of the left-side columns.

After grabbing that Medical Station, climb back to the top of the ship and fight more Agents near two Lightning Capacitors. The guide warns to wait for enemies to take position before you shoot the capacitors to stun and damage them. There’s also a Heavy and a Vanguard among the group, so don’t get complacent.

You then move down the left side again and back up, fighting more Agents and LOKI Mechs. When you return to the middle, the fight resembles the first one but is harder since you no longer have Lightning Capacitors to help.

After that, cross a small trench, then go left until path blockers appear as scale-like panels. Use the Panel Controls to trigger a short cutscene that lowers them, creating a route forward. Continue, turn left, and fight more Shadow Broker Agents. This time, Lightning Capacitors are available again, which helps because the group is large.

Conductor Components: 3,000 credits. This is described as tricky to find. Locate the Lightning Capacitor on the left-hand side during the fight, then head down one of the small ramps to the ship’s side; the Conductor Components sit between the two small ramps.

With loot in hand, climb back up and use the Rod Controls again to open the forward trench down the center of the ship. Go up the ramp and move straight ahead to find the Hatch Controls to enter. Inside, you can also loot:

Medical Station: 100 credits. On the right-hand side of the Hatch Controls door.

Interact with the Hatch Controls to trigger a cutscene and then a lengthy fight.

Defend the hatch

Your objective is to hold out near the entrance hatch until Liara’s “bypass shunt program” cracks it open. This requires handling multiple waves featuring Engineers, Vanguards, and even Rocket Drones. The guide says this should feel familiar by now, but the drones can still be annoying if you don’t use Singularity or Overload to zap them.

Liara’s bypass program is not time-based. It always takes exactly as long as it takes you to eliminate all five enemy waves. A hologram at least marks which wave you’re on.
Each of the five waves comes from a different direction. Unlike the earlier Hotel Azure fight, the locations are fixed this time, and the weather is worse.
The waves follow a pattern: the third wave is Rocket Drones in the middle, and the remaining waves alternate between left and right sides.
Best cover spots overlook the ramp you used to get here, each marked by a pair of Thermal Clips. However, the clips do not respawn—once used, you must break cover to salvage clips dropped by enemies.
A new wave only arrives after the final enemy of the previous wave dies. You can exploit this by leaving one enemy alive to buy time to collect Thermal Clips dropped by their allies.
Lightning Capacitors are the best friend here: if a foe is near a charged Lightning Capacitor, shoot the Lightning Capacitor.

After all five waves are cleared, Liara’s bypass program completes and you can finally enter.

Find Feron

Inside, you immediately fight Agents in a long hallway backed by an Engineer, which the guide describes as a good sniper position. Then the hallway turns left and the same setup repeats, swapping the Engineer for a Vanguard. After they’re down, loot time begins.

Up the next stairs, you’ll run into even more Shadow Broker Agents, including a Vanguard and Engineer. The area is cramped, so the guide recommends staying behind cover rather than rushing forward. After you clear them, locate the side room with a door you need to Bypass, plus:

Terminal: 4,500 credits. A laptop on a table next to the Bypass door.
Med Kit: 100 credits. On the ground beside the Bypass door.

After bypassing the door, you finally meet Liara’s partner. This moment can award Morality points:

Pick “Are you all right?” in the first dialogue wheel for +2 Paragon Points.

From here you can Investigate. Aside from asking about the Shadow Broker himself, Feron is shocked as soon as he tries to tell you anything. That doesn’t award Renegade points, but the guide calls it awful to watch. Instead, you can choose:

“We’re all leaving” for +2 Paragon Points.
“The Broker’s overconfident” for +2 Renegade Points.

After the conversation, you can get two more comments from Feron if you speak to him again.

Help Feron

Now you double back to the previous room and fight more Shadow Broker Agents. Luckily, this time they’re only supported by a Vanguard, though they’re still formidable. Once everyone is dead, go through the unlocked door at the end of the room and down the winding corridor. At the end, there’s one last Shadow Broker Agent.

Terminal: 4,500 credits. On the corner of the table at the end of the winding hallway, where the final Shadow Broker Agent is.
Med Kit: 100 credits. At the base of the wall behind the desk where the Terminal sits.

Go through the door to meet the Shadow Broker in a lengthy cutscene. There are no Morality points during that sequence, so respond however you want.

When the fight begins, the guide recommends your normal approach for anti-shield and anti-armor damage. Run whenever the Shadow Broker gets close. After depleting Shields and Armor, he pulls up a special shield that deflects bullets—forcing you into close range for a melee strike delivered through a mid-fight cutscene.

After each punching cutscene, the Shadow Broker restores his Shields and Armor and pulls out his own portable version of the Collectors’ plasma shield. Infiltrators can cloak and shoot him from behind, while other classes must shoot around the shield, use area-of-effect powers, or stagger him to create openings.

On the third successful punch, Liara ends the fight by destroying the Broker using his own information network. Nice!

In the aftermath cutscene, you get three chances for Morality points:

After Feron enters the room:
- Choose “You’re sure about this?” for +2 Paragon Points.
- Choose “Good. Useful Intel.” for +2 Renegade Points.
After Feron and your squadmate exit the room:
- Choose “[Hug her]” for +5 Paragon Points.
- Choose “It’s just nerves” for +5 Renegade Points.
At the end of the conversation:
- Choose “I’ll miss you.” for +2 Paragon Points.

That’s the Shadow Broker defeat. The guide adds that the mission doesn’t end your activities immediately—there’s still plenty to do in the Shadow Broker base itself.

Post-Mortem With Liara

After the main confrontation, you can return to the Shadow Broker base and talk with Liara again. If you romanced her, this is described as a very important conversation.

Pick “I want to talk about us,” then choose “I do” or “Let’s try again” to re-lock in the romance with Liara once you meet again on the Normandy SR-2.
Pick “Then let’s be friends” or “Okay. No hard feelings” to end the romance amicably.

Regardless of those options, the guide says you should then speak with Liara a second time to invite her aboard the Normandy SR-2.

The details of the second scene depend on whether you already completed “The Suicide Mission,” and on whether you ever romanced Liara in the first game. You can earn the following Morality totals:

“Thank you,” “I’m worried,” or “I’m hopeful,” plus “Too many still died” for +6 Paragon Points total.
“These aren’t mine anymore,” “I’m frustrated,” and “It was a damn setup” for +6 Renegade Points total.

The exact wording for the final Morality choices varies based on whether you romanced Liara and whether you tried to rekindle it in the earlier post-mortem conversation. Still, you can always obtain +2 Morality points of some kind—only the text changes.

Pick “Happily ever after,” “We’re here now,” or “Life everywhere” when they appear for +2 Paragon Points.
Pick “Survival,” or “Death, most likely,” and then “I don’t know” for +2 Renegade Points.
