Mass Effect 3 Attican Traverse: Krogan Team Side Mission Walkthrough

Attican Traverse: Krogan Team or Attican Traverse: The Rachni is a side-mission you can play after you finish Priority: Sur’Kesh.

Originally, the mission’s name is Attican Traverse: Krogan Team, but after you talk to Wreav in the War Room, the mission’s name will change to Attican Traverse: The Rachni.

When to start

After Priority: Sur’Kesh


“A krogan team has gone missing, and Normandy has received the NavPoint with their last-known coordinates. Investigate the missing team and find out what happened.”


Alliance Fifth Fleet, Aralakh Company War Asset


To start this mission, open the Galaxy Map, select Milky Way and locate Ninmah Cluster, in the central area, to the east. Enter the system and go to Mulla Xul, then land on Utukku.

Configure your team and equipment, and then watch the introductory cutscene. Talk to Urdnot Dagg for 2 Paragon/Renegade points.

When you gain control over Shepard, investigate the building to the left, where you will find: the M-300 Claymore I Shotgun (to the right), the Pistol High Caliber Barrel (on the other side of the barrack), and some Spare Parts you can salvage for 1625 Credits.

Exit and move towards your objective, down the canyon. When you exit the canyon, check the building to the left for the SMG High Caliber Barrel Mod and the Weapon Bench.

Upgrade your weapons, then exit the building and search the crates near it for more Spare Parts. Salvage them for 875 Credits.

Enter the building to the right, and eventually you will fall. Your next objective is to explore the tunnels. Advance and pick up the M-451 Firestorm near the dead krogan (to the right), then shoot the webbing.

In the next tunnel all you have to do is to follow the webbings and the pods, destroying them. They will lead you outside. When you exit, you will be attacked. Go left, and look near the mountain wall for Shotgun Shredder Mode.

Clear the area, and follow the passage to the left, to enter the next tunnel.

Destroy the barrier to the right, and advance, but make sure you look for a Krogan corpse in this area. It is behind a webbing and it holds a dying note required to complete the Citadel: Krogan Dying Message mission.

Eventually, you will enter a dark tunnel and you will be asked to reach the central chamber. At this point you should follow the passage to the right which takes you up. Destroy all pods and keep an eye on the left side of the tunnel for a Reaper Tech which can be salvaged for 3750 credits.

Continue to follow the tunnel and kill all Husks, Ravagers, Swarmers and Cannibals you encounter. The next point of interest is a waterfall along the path to the right. Here you will find the Ariake Technologies Shoulder Guard. Grab it and continue.

Move through the tunnels until you find the Reaper Node. Near it to the left you should see a Med Kit and the Pistol Piercing Mod. Destroy the Reaper Node and enter the Narrow Passage.

When you reach the main chamber, shoot the reaper node to the left, above the main structure then advance following the left path.

Kill everything that moves, then take out the next reaper node. Return to the first area, and repeat the last step on the right reaper node, to open the path forward.

After you clear the area choose your answers wisely during the dialogue with the Breeder.

If you go for a Paragon answer, you will win an ally. If not, you have to fight the Breeder. Complete the conversation and the mission will also end.

Achievement/trophy unlocked: Tunnel Rat.

Next side-mission: Ismar Frontier: Prototype Components.
