Collector Base: Infiltration

This mission is triggered as part of Stop the Collectors: Defeat the Collectors, once you have managed, after passing through the Omega-4 Relay, to get foot on the collectors base.


 * A Specialist Technician is required to infiltrate via the station's vents in order to circumnavigate the defenses and doors, in order to open the central gate for the rest of the squad. (Ideal: Legion or Tali. Non ideal: Thane, Jacob, Mordin or Garrus as they will die.)
 * A Fireteam Leader is required for the second team. The briefing conversation mentions that this member must be experienced in leading a team. (Ideal: Garrus, Miranda, or Jacob, Non Ideal: anyone else, as they will get your specialist technician killed.)
 * Your Team - will be fighting against Collector Drones, Harbingers, and several Collector Assassins, so it is wise to bring along members that wield biotics.

You will have to fight several Collector squads, while pressing forward to activate 8 different consoles alongside a path beside the vent your Specialist is in. The last few consoles are time-sensitive, so you should clear out the enemies as quickly as possible. It is advisable to save your game before you press the last button in case you pick the wrong character for the next session. The mission immediately ends after pressing the final button, so if time is running out it may be worth it to run to the button and press it even if there are enemies remaining.
