Collector Base: The Long Walk

This mission is triggered as part of Stop the Collectors: Defeat the Collectors, once you have finished Collector Base: Infiltration, reaching a room where you will be able to rescue your crew, or part of it, if you arrive in time.


 * A Biotic Specialist to generate a shield, protecting the squad against Collector swarms. (Ideal: Samara/Morinth or Jack (loyal). Non-ideal: Miranda, Thane or Jacob. Doing so will result in the death of one of your squad mates.)
 * Fire team Leader for the second team. (Ideal: Garrus, Miranda, Jacob. Non Ideal: Anyone else. There is a possibility of this leader dying as the doors close at the end of the long walk.)
 * An Escort to guide the Normandy crew back to the ship. However, you can't use this person for the final battle. Choosing no one results in the death of the Normandy crew. (Ideal: Any loyal teammate that was not assigned as a specialist or fire team leader. Non Ideal: A team member that you have not secured loyalty from. This squad member will perish while escorting the Normandy crew, as will the crew.) Note: Sending Mordin may be ideal, because he has a chance of randomly dying if he doesn't escort the crew back, even if he is loyal and all other choices have been done correctly.
 * Your Team - You will be fighting against Drones, Harbinger, Assassins, waves of Husks and Abominations, and one Scion.

The Biotic Specialist you have chosen will erect a dome-shaped biotic shield encapsulating the squad from Collector swarms. Note: moving outside of the biotic barrier will cause damage to Shepard and eventually result in death. The Biotic Specialist will move slowly through the level and stop three times for you to fight off a wave of enemies before proceeding. The waves encountered are:
 * 1) Drones and Harbinger
 * 2) Husks and Abominations climb up from a ledge then Drones, a Harbinger and Assassins will appear.
 * 3) Husk, Abominations and a Scion.
