Chapter 1: CitadelEdit
Many assignments will become available on the Citadel and can be completed to develop sideplots and gain rewards; walkthroughs for each individual assignment are available. Also while on the Citadel you will encounter merchants who will sell you useful items and buy your old ones. You can consult the Merchants Guide for a complete list of game locations.
Main Plot ProgressionEditMako, as well as sections where you will engage in Combat on foot; follow the links in this sentence for detailed information.
You will also be given the opportunity to perform various galaxy-wide assignments. These are all optional but can be useful for the additional items and experience they provide. Assignments will be offered to you directly, but you can also find them yourself simply by exploring planets that you find via the Galaxy Map on the Normandy.
In between missions and assignments you may wish to walk around the Normandy and converse with your crew. This will not only reveal interesting information, it will occasionally produce opportunities for new assignments and will allow you the option of pursuing a romance if you visit frequently enough.
Note: Once you reach level 20, the next time you access the Galaxy Map you will receive the UNC: Rogue VI assignment on Luna. It is recommended that you proceed there immediately, as this assignment unlocks your specialization class.
Chapter 2: Finding LiaraEdit
In Chapter 2 you will have the opportunity to recruit a new squadmate, if you can get past the geth. This mission, while substantial, is slightly shorter than Noveria and Feros.
Chapter 3: NoveriaEdit
On Noveria you will search for Saren's associate, Matriarch Benezia, facing geth and a powerful biotic boss.
Chapter 4: FerosEdit
The Zhu's Hope colony and the Exogeni facility have been overrun by geth and krogan. Why is Saren interested in this tiny outpost?
Chapter 5: VirmireEdit
On Virmire you must thwart Saren's plans and make a fateful decision; you will also converse with an ancient enemy.
Chapter 6: LockdownEditIlos. However, the next time you use the Galaxy Map, Joker will give you a message and you're returned to the Citadel.
The Council, with Ambassador Udina, have unfortunately decided that you don't really need to go geth hunting or determine what the Conduit is after all. They think that the Reapers are a lie created by Saren, to distract them from his true goal of attacking the Citadel. They have decided, in fact, to ground both you and the Normandy. If you've been following a romance path, you'll then have a short scene with your love interest before duty calls: Captain Anderson has a plan and asks you to meet him in Flux.
This is your last chance to complete any assignments on the Citadel, but if you speak to Captain Anderson, don't panic as he gives you the option of saying you are not ready to go yet. There are only two new assignments on the Wards: Citadel: Our Own Worst Enemy and Citadel: Negotiator's Request, both of which are very brief. Once you're ready to leave, speak with Captain Anderson. He will offer to help you steal the Normandy and—hopefully—get to Ilos in time to stop Saren.
Captain Anderson has two plans to override the lockdown on the Normandy, both at great personal risk. He can either break into a C-Sec-secured area, or hack Udina's computer. You can choose for him, or give him the choice: Anderson will select the ambassador's computer if you let him choose. Then return to the Normandy to wait: different choices show different cutscenes, but either way the Normandy escapes the Citadel.
After you've taken to the skies, you're again free to choose your destination, and Ilos will now be available. You can no longer return to the Citadel, since you are now a known fugitive and mutineer.
Chapter 7: IlosEdit
On Ilos you must pursue Saren as he races to find the Conduit. Note: Once you head to Ilos the game will proceed in locked progression: you will no longer be able to use the Galaxy Map, walk around the Normandy, or complete assignments.
Chapter 8: EndgameEdit
You have found the Conduit and must now stop Saren once and for all!
Finally, the matter of the Council remains. If you chose to abandon the Council, a human chairman will preside over a newly formed Council (a wholly human Council, if you were a Renegade) with a choice between Udina or Anderson as chairman. If you chose to save the Council, humans will be invited to join the Council, again with a choice between Udina or Anderson as representative. Alternatively, you can disclaim interest in politics and politicians.
Level Caps and Repeat CareersEdit
Mass Effect ends after the completion of the storyline. Your character is saved and can be carried over to Mass Effect 2, receiving bonuses on starting level and credits; decisions you have made, both major and minor, will also be remembered and will affect events in future games.
A new game must be started to continue playing after the final act, though you are allowed to carry over your character for a "new career" for the same Shepard. You can then explore the galaxy again, plus you'll have all the plot worlds available again as well. The main character's level, talents, specialization and equipment all carry over, but Paragon / Renegade scales, weapon manufacture licenses, and medi-gel / grenade stock upgrades are reset, as are your Codex entries and assignments. Any combat, biotic or tech achievements will be usable in any new career.
After you beat the game, you can start your character over by going to "Create New Character" and selecting the bottom most option (Select Existing ID). You then restart the story with all of your experience and items intact from the previous game. All items that were equipped on other characters are transferred to you, and you gain doubles of anything you equipped. For your main character, all of your talent points remain spent as they were before. Your party members all begin at the same level as you, but with no talent points spent and only the basic weapons / armor, allowing you to rebuild them as you like.
It is possible to reach level 50 on your first playthrough, but you won't achieve it without completing a majority of the side assignments. Since you are capped at level 50 for your first time through the game, you cannot reach level 60 until the second playthrough with your original character. If you're looking to reach level 60, it isn't necessary to reach level 50 in your first completion. You can also start a completely new character if you'd like to try a new class, gender, background, etc, and you will no longer be level capped at 50, but there is not enough XP available in the game, even with DLC, to reach level 60 in a single go.
