This Mass Effect 2 walkthrough of all 6 available classes serves as your video guide to how to best start and finish the sci-fi action-RPG game on Xbox 360, PC and PS3.
Remember, even if you’re using a Mass Effect 1 savegame to continue the sequel (detailed how in a video below), at some point at the beginning of Mass Effect 2 you’ll be given the choice to change classes. Considering how much some of them have changed in between the two games, you might want to carefully consider it. The story will even account for the changes. What Mass Effect 2 class will you play as?
New PlayStation 3 gamers will want to make sure that the story choices they are asked to choose from at the start of the game save the Rachni Queen/species as they could be vital support for surviving Mass Effect 3 in 2011. Same story with Wrex, if you save him he’ll be uniting the Krogan warriors.

How to import Shepard from Mass Effect 1 into 2:
This video walks you through the process of importing your male or female Commander Shepard character from a Mass Effect 1 savegame into Mass Effect 2. So you can continue playing as-if nothing changed between the two games. — Note: If you do not load a previous savegame into Mass Effect 2, the sequel assumes the paragon ending of the first game where Shepard let the entire Citadel council die and humans are now leading the galactic species. With Shepard sent off by them on a mission to kill the threath of the remaining Geth. — Here’s the how-to importing tutorial.
Mass Effect 2 Tour of the Normandy 2:
A Tour of the Normandy 2: BioWare producer Adrien Cho gives a sneak peek at some selected highlights around the interior of the SSV Normandy SR-2.
Here’s what the Normandy 2 decks overview is like:
EDI, the A.I. voice of the Normandy 2 starship (voiced by Battlestar Galactica actor Tricia Helfer) will point you in the direction of your first mission. Get additional info about Normandy by accessing terminals throughout the ship, which will display a holographic floating blue sphere that represents her for communication. Now, let’s take a look at life on a starship:
Mass Effect 2 Walkthrough
In Mass Effect 2, players will once again step into the role of the heroic Commander Shepard, commanding their crew of some of the most dangerous operatives from across the galaxy on a mission so challenging that it’s potentially suicidal. Featuring intense shooter action, a rich futuristic storyline, space exploration and emotionally engaging character interaction, the game delivers an unparalleled cinematic experience.
Storyline recap: In 2183, the heart of the galactic community suffered a devastating attack.
The Citadel space station was invaded by a synthetic geth army attempting to open a portal for the Reapers: enormous machines that eradicate all organic civilization every 50,000 years. Commander Shepard led the defense, but the Citadel Council was lost.
Now, the new human-led Council attempts to quell rumors of the Reapers’ return. Hoping to ease public concern, they’ve sent Commander Shepard and the starship normandy to wipe out all remaining Geth resistance…
Watch the Prologue titled “Save Joker”.
…Two years after Commander Shepard repelled invading Reapers bent on the destruction of organic life, a mysterious new enemy has emerged. On the fringes of known space, something is silently abducting entire human colonies. Now Shepard must work with Cerberus, a ruthless organization devoted to human survival at any cost, to stop the most terrifying threat mankind has ever faced.
To even attempt this perilous mission, Shepard must assemble the galaxy’s most elite team and command the most powerful ship ever built. Even then, they say it would be suicide. Commander Shepard intends to prove them wrong.
This Mass Effect 2 walkthrough is being done as a Renegade Sentinel on Normal Difficulty.
Starting from now, the Prologue and up until the ending of the game. Each video has been split into individual parts. It is hard to try and organize this game. Feel free to make your own decisions when they come up, but those decisions may or may not change the outcome of events to come, different from mine.
Watch the Prologue titled “Awakening” that includes the first gameplay and explains how it is that Shepard is alive.
This mission is very short. You do not do much fighting in this one. The only real trouble is the enemy near the end of the mission. There is no particular order that you must complete these missions in, for the most part. Time to meet Tali and find out more about the Collectors.
Bug warning from James: “When I walk through the big door, just before meeting Tali, I died from the Mechs. The screen went bloodshot and Shepard ragdolled and died, but then it froze like that, I could look around order my squad but I was dead… ended up having to exit to main menu after 5 minutes. Returned to the scene, but did not die again.”
After completing Freedom’s Progress you will be shown this cutscene. You are now in charge of the new Normandy SR2 and have to put your squad together. Take a look around your new starship Commander.
Omega has three missions you can complete without leaving, we split them into three videos. You will be staying on Omega after this video to pursue Dossier: Archangel.
Mass Effect 2 Walkthrough Part 6 – Omega: “Dossier: The Professor part 2”
This is the second and final part to Dossier: The Professor. It’s time to recruit the “good” doctor as a companion for your team.
Part 1 of this Archangel team member recruiting dossier is the final mission at this moment in time in the game for Omega’s Missions. There will be more later in the game, especially in Side Missions to come.
Mass Effect 2 Walkthrough Part 8 – Omega: “Dossier: Archangel part 2”
This is the concluding part to the “Archangel” Dossier.
For The Convict Dossier taking place on the Prison Ship Purgatory in… you guessed it…. Purgatory, you travel to The Milky Way via the Mass Relay. Exact location is the Hourglass Nebula: Osun: Prison Ship Purgatory.
There is not much to this Mission, you are here to recruit Jack AKA Subject Zero. When asked to relinquish my weapons I opted to say no. There probably is not that bad of an outcome or much harder if you choose to give them up.
The Warlord Dossier is located on Korlus, which you can find in the Eagle Nebula’s Imir: Korlus. Here you will be recruiting the Krogan for your squad.
Mass Effect 2 Walkthrough Part 11 – Korlus: “Dossier: The Warlord part 2”
The continuation of Shepard obtaining the Grunt.
No matter what order you recruit the first four squad members, after the 4th you will be brought to Horizon. Now after watching the cutscenes, head to the Briefing Communications Room as shown in the video to activate the Horizon mission to investigate the Collectors threat and watch the next few minutes of cutscenes. You’ll be looking into what happened to the Colony.
Mass Effect 2 Walkthrough Part 13 – Horizon part 2
Here’s the final video of Horizon. As the preview image shows, you get to meet your old crew mate Ashley, at least if she survived the first game or you’re using a default new game. — The ending of Horizon Part 2, the cutscene, shows Dr. Okeer’s Legacy.
You’ll be able to find Tali by traveling to Haestrom in Far Rim: Dholen. Once there, you’ll be recruiting Tali to your squad. You will also need to insert Disc 2. Note: Because of an error, the first 6 minutes of this video guide section are as a different character. But the same decisions were made.
This mission is located on Illium, which can be found in the Crescent Nebula’s Tasale. Here you will be recruiting Thane AKA Assassin. Once you arrive on Illium, you will need to talk to your old friend Liara to gain information on him and Samara AKA The Justicar.
Mass Effect 2 Walkthrough Part 16 – Illium: “Dossier: The Assassin part 2”
Here’s the final part to recruiting the master assassin Thane.
You may want to stay on Illium as the next recruit mission is here too. Make sure you have talked to Liara for her information if you have not already. Let’s recruit The Justicar AKA Samara!
Mass Effect 2 Walkthrough Part 18 – Illium: “Dossier: The Justicar part 2”
Here’s the second part to recruiting the code-abiding biotic Samara.
Bug warning from Reverend: “Unable to exit the mission where you have to retake a freighter from Blue Sun. Used the instructed key and it is stuck, now I can run around the area but as I have come in through a hatch I am unable to leave. No amount of reloading and running around like a loony has helped.”
Next you get to travel to the Citadel, it’s located in the Serpent Nebula: Widow. Here you are requesting a meeting with The Council. I cannot confirm this “mission” is absolutely necessary to do. It is not long though. It’s basically just one big cutscene and some walking/running and you leave.
Bug warning from Steve: “If you are unable to continue on with the main storyline on Stop The Collectors, you may have a glitched game where you may need to do more than one mission to unlock it and continue the game. I experienced this one time of three playthroughs.”
I went ahead and had to do both “Jacob: The Gift Of Greatness” and “Garrus Eye for an Eye” missions. These should not be the two particular team mate loyalty missions you have to go and do, but are just what I chose. Otherwise, if you choose not to help any team characters and let them die during the Suicide Final Mission. Then you can go straight to Stop The Collectors instead.
This optional loyalty gaining mission is located on Aeia in the Rosetta Nebula: Alpha Draconis. Keep in mind that if you wish to have all your squad members survive the Suicide Final Mission this is necessary to complete.
You will need to build each loyalty for each member. Also you will need to choose the right job when the time comes then as well. There is an achievement for the Suicide Mission too.
This next mission is an optional loyalty mission for Garrus.
You should continue with loyalty missions anyways, however, I only did a few.
FRIENDLY WARNING: If you want every one of your team members to survive the final mission of the game, then scroll down to the sections titled “How All Crew Members Can Survive The Final Mission” and “Normandy Upgrade Guide” to find the full instructions. With that done, you are prepared to start the final mission at full strength.
Here’s where essentially the final mission of the game “Stop The Collectors” starts as you investigate the Collector ship.
Mass Effect 2 Walkthrough Part 23 – Investigate Collector Ship part 2
This next video is the final video to investigating the collector ship.
Before you can continue to stop the Collectors, you need to acquire the Reaper IFF, which gives you access to the Omega 4 Relay. Once you finish this mission and have the IFF device (our Reaper IFF part 2 video), you will also have the choice to recruit a new squad member Legion by reactivating him.
Mass Effect 2 Walkthrough Part 25 – Reaper IFF Part 2
Mass Effect 2 Walkthrough Part 26 – Reaper IFF Part 3
You will now be playing as Joker for this “Activating the IFF” section.
PS: Unfortunately skipped in this footage is EDI showing a sense of humor. Joker complains he’s probably dooming humanity by giving EDI control over all of the ship’s systems during the Collectors attack on the Normandy. The discussion between them is that he needs to avoid detection by crawling through the ducts to access Engineering…
…In reply she jokes “I enjoy the sight of humans on their knees” leaving Joker standing there baffled… until she points out she wasn’t being serious. 😛
Technically this is “Stop The Collectors #4: Suicide Mission” as this mission consists of several stages. Only a few more stages left.
Mass Effect 2 Walkthrough Part 28: Stop The Collectors Part 2
In a few minutes you’ll be asked again to pick your squad members to complete certain tasks, make sure you pick the correct ones if you want them to survive. Who to choose when, is explained in the section headlined “How All Crew Members Can Survive The Final Mission” that can be read by scrolling down a little on this page. Good luck!
Mass Effect 2 Walkthrough Part 29: Stop The Collectors Part 3: Ending
You’ll be destroying the four feeding tubes of the Human-Reaper. Then you will also be destroying the Human-Reaper Larva endboss. Afterwards the storyline is over. Here’s the ending to the game!
This video was the final part of this Mass Effect 2 walkthrough. We hope you’ve enjoyed all the hard work that was put into making this video guide.
Upgrade all Normandy Systems (described below). Do all Loyalty Missions (talk to each team member). Once you reach the Collectors base in the Final Mission. You’ll have to send your loyal team members to do certain tasks in the following specific order for all of them to survive. These choices will come up as you play through the final mission.
1. Tali or Legion should go into the station’s vents to do hacks;
2. Garrus, Jacob or Miranda should lead the secondary squad;
3. Jack or Samara/Morinth should protect you with a biotic barrier;
4. Mordin (or Tali) should escort the starship crew back;
5. Miranda or Jacob (or Garrus) should lead the secondary squad the 2nd time;
6. Grunt, Garrus or Zaeed should hold the line. Make the defenders team rear guard you.
Aside from doing all your crew member’s loyalty missions to ensure they live, several upgrades can be researched to upgrade Normandy SR-2 starship. By improving the weapons, armor, and shielding with upgrades you affect the success of the final mission. How it changes the ending of the game: For each upgrade you don’t buy, one team member will die during the Collector base attack.
