Main Missions - Mass Effect 3

In the following list we have included links to pages with walkthroughs of specific missions, as well as additional pages on how to prepare for the campaign's grand finale. Also, we have prepared information about the available game endings. The hashtag numbers, that is, #2 and #3 in the title of The Citadel quests, indicate your returns to The Citadel as part of the main storyline.

Side Missions - Categories

In this guide, side quests have been divided into four main categories:

Citadel Missions - These are all missions that are completed entirely on the Citadel without leaving it.
Missions beyond The Citadel - These are all missions that you complete in other corners of the galaxy (such as Grissom Academy).
Mini-Tasks - These are short and uncomplicated missions that usually consist in finding and delivering an item (such as a protean artifact).
N7 Tasks - These are all N7-type missions commissioned by Traynor the specialist that can be completed on the maps available in the co-op mode.

List of side quests in The Citadel

Note - Some smaller quests do not appear in Shepard's journal (we inform you about it at the beginning of the quest's description). Do not ignore them, but deal with them as well.

List of side quests outside The Citadel

Some of the following quests are important, for example, for meeting important NPCs or engaging into a romance. Try to complete 100% of them.

List of mini-tasks / minor side quests

Note - Some small tasks and missions may not appear in Shepard's journal (we inform you about it at the beginning of the quest's description). Do not ignore them, but deal with them as well.

List of N7 side missions

Note - N7 side quests may contain references and links to other optional side missions. For possible references, check the walkthrough of particular mission.

After you complete each main quest, I'd recommend speaking to every member of your team, read messages at Shepard's terminal, head to the Citadel and explore all newly unlocked systems. It will increase the chance of gaining access to all new side quests.

Not all quests are unlocked by speaking to the NPCs. Some are added to Shepard's journal when you find a certain item or overhear a conversation. Exact information about unlocking particular quests can be found in their walkthroughs.

The names of all the missions correspond with the ones in Shepards journal - Mass Effect 3: All missions and quests - list - Walkthrough - Mass Effect 3 Guide

How to use the walkthrough?

The names of all the missions correspond with the ones in Shepard's journal. If you want to find the description of a given quest, you first have to check its name in the game and afterwards find it in the guide. Small quests that don't appear in the journal (e.g. visiting a wounded friend in the hospital) are an exception.

At the very beginning of each quest description you can find a short info about the quest giver and requirements you need to meet to unlock it. Whereas at the end of the walkthrough you will find a note about the next mission in order (of course only if a given mission belong to a longer series).

Color markings in the guide

The guide contains the following colour symbols:

Red refers to the names of the missions.
Blue refers to the locations you visit.
Green refers to items that you find, both those which you can take with you and those that can be only looked at (e.g. palmtops or computer terminals).
Orange refers to war assets, intel and experience points. In the later case the abbreviation EXP is used. For example, [800 EXP] means that you can receive 800 experience points for a given activity.
