Mass Effect 2: Collector Base: Long Walk - walkthrough Mass Effect 2 guide, walkthrough

Last update: 02 June 2021

Description: Take your time to familiarize yourself with the basic rules of this mission. You'll have to remain inside the force field created by your biotic, because otherwise you would start losing health (first screenshot). Talk to your biotic once you're ready to begin this part of the final mission.

Make sure to have a heavy weapon ready for use, because you'll soon encounter a group of Collectors and a Harbinger will pop up on the battlefield from time to time. I would recommend that you wait until your biotic stops and allows you to take cover (second screenshot) before you start attacking enemy units.

Eliminate all the hostiles, choose your standard weapon again and talk to your biotic to continue the long walk. Be careful, because you'll soon notice a group of husks and abominations running towards you. Eliminate them from a larger distance and don't forget that abominations explode when they die. Keep moving forward until your biotic stops again. Order your team to take cover behind a nearby object (second screenshot).

You'll have to be extremely careful here, because your enemies (including new Harbinger forms) will have a clear view, making it easier for them to attack your team. Aside from standard Collector units you'll also have to kill a few guardians and don't forget to destroy the shields first or to flank them for a quicker kill. Talk to your biotic once it's safe to move.

Continue your approach. Even before your biotic makes a stop you should start attacking new zombies and abominations heading your way. All the monsters must die quickly, because soon you'll have to focus your attention on a scion seen in the distance.

I would strongly recommend using a heavy weapon against the scion. Continue attacking this beast and stop only if a lot of zombies are near of your position. Don't forget to heal your team members, but only if they all drain their health bars. Talk to your biotic when it's safe. Only one more group of monsters will attack you along the way, but it won't be a problem to kill them. Keep heading forward until the games triggers a cut-scene.

I guess you won't be surprised to hear that you'll soon have to manage your team again. This is the last time you're doing this. You're going to have to make only crucial decision and that is to choose followers which will stay by your side until the end of the game. I would recommend choosing Miranda or some other biotic with Overload ability. As for the second follower, you should make a choice depending on your character's class and preferred style of play. Make sure that AT LEAST one soldier stays behind to help the rest of your crew in repelling Collector attacks. My recommendation is to leave Zaeed, because you may want to consider taking Grunt with you.

Before you set off on a new mission you'll be given a chance to make a speech again and this is going to be an opportunity to earn paragon or renegade points. Next part of the final mission is described in Collector Base - Finale: Part 2 section.
