Prepare your squad to fight rachnii. After landing on Altahe head to the listening post (Altahe - 5).

There will be some rachnii outside it. Eliminate them without leaving Mako. The rest of opponents will spew from nearby holes. After killing them enter the building. You'll encounter more rachnii.

In the room on the south west you'll find the terminal. Access it to learn the coordinates of place from where rachnii shipments were sent.

Hint! This assignment can be done only after completing mission on Noveria (7).

You'll get this mission after entering Ereb system or by receiving the call on Altahe (13.14.1.1. Listening post Theta).

Land on Nepmos and head to the listening post (Nepmos - 8). You'll find a group of Alliance soldiers pinned down by legions of rachnii. Your task is to help them defend themselves.

Hint! You can make it easier by hooking up Mako's power supply to nearby generator. This way you'll reactivate the turrets.

After dealing with third wave of enemies you can talk with lt. Durand to learn the coordinates of second listening post and to activate assignment 13.14.1.1. Listening post Theta.

Your next task will be to clear nearby mine infested by rachnii. Go there (Nepmos - 6) and enter inside. You'll be attacked by rachnii. It's best to retreat to the entrance and eliminate the enemies gradually (there will be a lot of them).

Then you'll have to kill two powerful and strong rachnii warriors, each supported by four soldiers. You'll find them in rooms on the north and the north east of the mine. After clearing the mine, assignment will be completed.
