This is a brief guide intended to outline a reasonable order to complete 100% of all missions and assignments. It covers experiencing virtually all of the content of Mass Effect.
There are a number of other excellent achievement specific guides listed below. These should also be consulted for specifics concerning those achievements.
Note that this is not intended to be a walk-through in the usual sense: it is more of a checklist. It is not necessary to complete the game more than once to gain the "Completionist" achievement.
This checklist will provide one possible order for accomplishing all of the missions and assignments.
Note: Avoid triggering any assignments!
Finding Liara T'Soni
Note: If you are already at least level 20, it will be impossible to avoid triggering the UNC: Rogue VI assignment at this point. This will not adversely affect the ally achievements, as only 75% of the assignments are necessary.
The Citadel Redux
Uncharted Space Redux
Note: This is the final opportunity to complete assignments outside of the Citadel.
Multiple Characters and Replays
In order to experience every possible assignment and to gather all possible achievements, it is necessary to play through Mass Effect at least four times. If one follows the possible career paths:
- the first game will yield all but three of the assignments and the majority of the achievements;
- the second will yield a few further achievements;
- the third will provide two further assignments and several more achievements;
- the fourth will see the final assignment and finish up the last possible romance combination.
Further replays may be required to gain the Extreme Power Gamer achievement and/or the various talent achievements.
When creating a custom Commander Shepard, several immutable characteristics must be chosen which will affect all future play using that character, even if a new game is started.
The default "quick start" Commander Shepard is a male Soldier, Earthborn, and a Sole Survivor.
Morality affects certain dialog choices available during each game (and therefore the outcome of certain assignments) as well as a morality-specific mission. A character's morality is represented by running tallies of Paragon and Renegade points (to a maximum of 330 each). Accumulating Paragon points unlocks higher levels of the Charm talent; Renegade points unlock Intimidate levels.
When starting a new game, Paragon

Some assignments are listed more than once; this is intentional and is intended to make them simpler to find by listing them in all relevant contexts as they appear in the Journal.
