This is my favorite guide on the Citadel. Our Mass Effect 3 Walkthrough covers the entire spectrum of the single player story, multiplayer tips, and how to build a powerful army.
Shepard and the Crew
In Mass Effect 3 Shepard has access to six classes, all of which have appeared from the previous two games. Soldier specializes in use of weapons and combat, Engineer relies on expert tech skills, and Adept is a master of biotics. The three hybrid classes are Infiltrator that balances combat and tech, Vanguard that has both combat and biotics, and last Sentinel may access tech and biotics. There is no overall best class, it's all about personal taste. However, keep in mind that Soldiers can gain the largest weight capacity, the hybrid classes have mid weight, and both Adept and Engineer have low weight.
Shepard's companions depend on the choices imported from the previous two games. You will always have Liara, James and EDI as squad members. You can gain Ashley or Kaidan depending on who was left on Virmire during Mass Effect. Garrus and Tali may join only if they survived the suicide mission from Mass Effect 2. Last, you can gain Javik by buying DLC or owning the collector's edition of Mass Effect 3.
For both Shepard and your squad it's best to concentrate on one skill and max it out before moving onto a new one. Still, it is nice to spend a single point and unlock one or two abilities. Keep in mind that Shepard gains around double the skill points of other team members, allowing you much more flexibility.
The Soldier class can use all ammo types, has access to frag grenades, and gains the highest weight limit. Among their special abilities include adrenaline rush to slow down time and the knock back attack concussive shot.
We recommend investing in a single ammo, either incendiary ammo to destroy pesky armor, or cryo ammo to keep the enemy slowed down. Disruptor ammo is good for shields, but there are many more abilities that can easily take those down. The second power you should heavily invest in is frag grenade, which does a huge amount of damage over a large area of effect. Just remember that you will need to restock grenades at ammo crates.
Once powering both ammo and grenades, go for either adrenaline rush to boost damage and accuracy, or combat mastery to help improve reputation. We don't recommend wasting points on concussive shot as it's more effective to simply kill the enemy instead of knocking them down; both Garrus and Ashley are better suited for this task.
The Engineer has only tech abilities which in turn means no ammo, grenades, or biotics. Their two unique abilities include building combat drones and sentry turrets that will damage nearby enemies. The rest of their skills overlap with both the Infiltrator and Sentinel. Because you'll want to maintain low weight, consider carrying only a pistol and SMG.
The most devastating of the Engineer's abilities is Overload, which can quickly destroy both shields and barriers while doing a great amount of health damage. It is high damage, quickly deployed, and has a fast recharge. The second ability you should quickly invest in is Sabotage, first off for it's ability to disable enemy weapons, and second to hack turrets and geth.
You'll of course want to invest heavily in tech mastery for reputation and bonus damage, but don't neglect other skills. Sentry Turret dishes out a huge amount of damage and will keep the enemy distracted, making it much more potent than the weaker combat drone. Just remember that the turret has no mobility and you will need to summon it again to get in a better shot.
The Adept cannot use special ammo, but does have a unique grenade. The rest of their skills comprise of most of the major biotic abilities. Besides the lift grenade, the other Adept unique skill is singularity, which will suspend enemies in mid air as long as they don't have shields, armor, or barrier up. They have a low weight limit, and in turn should only use the lightest weapons.
Singularity should be your prime attack, but even with such a great skill you'll have to deal with enemy protection. This is why you should also invest a large amount of points of both cluster grenades and warp, which can be used to whittle down those pesky defenses.
With any remaining points boost biotic mastery for more powerful abilities and reputation. Alternately, (or if you get to a high enough level) star building up either throw or pull to help with biotic detonations set up from warp.
The Infiltrator uses a mix of combat and tech. They can use both cryo and disruptor ammo, have stick grenades, and can cloak. While they have abilities to further boost sniper rifles, the Infiltrator can make use of all weapon types. In fact, there many be some tactical advantage to cloaking with a close range shotgun.
As with the Soldier you should quickly level up both cryo ammo and your special grenade. Afterwards you should start using points to gain enough sabotage to quickly hack and increase tactical cloak's duration.
As with every class, operational mastery is great to increase reputation early on. Because you'll most likely be using a powerful sniper rifle or shotgun that can dish out heavy damage, it's typically not worth the points to build up incinerate.
Vanguards can get in close and really cause trouble with their range of biotics. They are the glass cannon of the game: putting themselves in great danger to deal very high damage. While shotguns are a perfect match, any weapon will service.
Both the skills biotic charge and nova should be your bread and butter skills. You can use charge to get in very close to the enemy and then expend your barrier to smash a group with nova. The reverse is also true: first beat down a cluster of foes with nova, and then use charge to escape to safer ground.
After having those two biotics mastered, turn your attention to one of the ammo types. Vanguards lack other skills to break down shields and armor, so you'll need to rely on your ammo choice in those situations. Shields are typically not much a problem if you have a SMG, so stick to Incendiary ammo for tough armor.
Because you'll be in the thick of battle, boosting your defenses and melee damage via fitness is recommend. Still, don't forget about assault mastery, which further boosts weapon damage and the much needed reputation bonus.
Sentinels have some of the best defensive techs and biotics in the game. Using these in conjunction will allow you to survive the worst situations and become a master controller. Sentinels also have access to a special biotic grenade that deals fair damage, but is more to fling away weaker enemies.
The main offensive skill you should build up is overload, which deals a large amount of fast damage to shields, barriers, and health. Further pair this tech with biotic warp to have two abilities that crush all forms of enemy protection.
Now for more defensive abilities: you'll want a good score in tech armor to keep yourself well protected. You'll have boosted shields, but powers will take extra time to recharge. Because of this, you should either use very light weapons (SMG+pistol), or just go all out with both types of rifles.
There are eight possible party members, though you can only gain a max of seven at a time (even it the DLC). Anderson will also join you temporarily at the start of the game, but it's for such a short amount that it's not worth covering his abilities.
James is an Arms Master who hits hard and has a large amount of shields and health. He can use an assault rifle and shotgun. If you speak to him enough he will teach Shepard Carnage and Fortification.
James is mainly a heavy tank that can take a large amount of punishment. Because he starts out tough on his own it's actually better to balance him out with more offensive abilities. Start by investing in the deadly carnage skill, followed closely by frag grenades. Last, the remaining amount of points should go into the Arms Master passive skill.
Ashley is an Alliance Officer and will join you if she was saved on Virmire during the first Mass Effect (or picked this option on a new Shepard). She uses both sniper rifles and assault rifles, though some of her skills favor the latter. She can teach Shepard inferno grenade and marksman after speaking with her enough.
You should first invest in the powerful Marksman ability to increase her rate of fire, followed closely with concussive shot to allow her to knock down enemies. After that it's a good idea to boost her damage output through her Alliance Officer passive.
Kaidan was a L2 biotic that exploded all over Virmire. Oh wait, he lived for you? In that case he joins as an Alliance Officer in palce of Ashley. He uses pistols and assault rifles as his main weapons. He can teach Shepard to use Reave and Barrier.
Reave is Kaidan's most potent ability and should be the first you invest in. Alliance Officer passive should be leveled second in order to further bosst Kaidan's skills. For the remaining points go for Overload if non one elese on your team has it, otherwise Barrier will do nicely.
Liara is a Pure Biotic that has access to some of the best biotic abilities. In turn she can only use puny light weight guns: the pistol and SMG. She can teach Shepard Stasis and Warp Ammo by talking to her.
As a biotic expert, you should first invest points into her powerful singularity to crowd control enemies and provide a small amount of damage. Next, boost Pure Biotic to make singularity even more powerful. You should have a good amount of points after that, so go ahead and purchase a few levels of stasis and increase its duration.
Garrus will join the team if he survived the events of Mass Effect 2. Much like an Infiltrator, Garrus uses a mix of combat and techs. His two weapons of choice are the sniper rifle and assault rifle, and many of his skills further boost sniping. He can teach Shepard armor piercing rounds and proximity mines.
As mentioned among Shepard's possible skills, overload is a great choice for Garrus. His armor piercing rounds are very powerful for taking down the worst enemies: atlas mechs, banshees, and brutes. Also don't discount proximity mines, as they deal heavy damage and can either be deployed quickly or set up as a trap.
EDI is one of the new characters who will join regardless of what save you imported. She uses a good array of techs and wields a SMG and pistol. She may teach Shepard defense matrix and decoy by talking to her.
If Shepard does not have overload themselves you should quickly acquire this powerful ability for EDI. Otherwise go straight for the armor damaging incinerate; unlike Shepard, EDI will not have the high damage weapons to make up for missing this tech. Decoy is also a great skill to keep the enemy busy. Last, unshackled AI should be taken over the last ditch defense matrix.
Tali'Zorah vas Normandy
Tali will return to your squad if you recruited her back in Mass Effect 2 and she survived the suicide mission. She is considered dead if she was not rescued in ME2. Her weapons in ME3 are the same as the last game: a shotgun and pistol. She can teach Shepard both energy drain and defense drone.
Sabotage should be her main skill as it can take out enemy weapons and control synthetic enemies. You should pick one of the two drones to invest in, namely the more offensive combat drone. Energy drain is a somewhat weaker version of overload that also steal shields; only go with this if for some reason you have no one else with overload. Last, her passive Quarian Machinist will add a lot to her skill output.
Javik is a cut character that can only be gained from DLC or the collector's editon. Either way you'll have to pay Bioware more money to use this character. He uses assault rifles and pistols. He can teak Shepard btoh Slam and Dark Channel after speaking to him enough.
Pull and Slam are Javik's strongest abilities. Stick to the former if you want to use him for utility, and the latter if you want pure chaos. Afterwards purchase Vengeful Ancient for more power and weapon damage.
@ Verne: Well the Rannoch end level boss of course. The giant laser beaming one. It was really hard to defeat it and this certain walkthrough was not a big help, so I checked wiki and found some useful tips. There was no chance that I could beat the boss without tips from wiki.
@khatibi22 Hmph ... I replied to this but don't know where my reply went.
Go to the left of the chasm and target the the boss with the designator.
As I recall, he shoots low and raises his aim point until he hits you. Before the laser gets high enough to hit you, cartwheel to the right and continue targeting him. He should get slammed from space before his laser gets you.
For the next round, go to the right side of the chasm and target him. Target him with the designator and cartwheel to the left when his laser gets close to you and continue targeting him. Again he should get stomped before his laser toasts you.
Go back to the left and repeat.
As I recall, once you get a hang of the pattern to use it's not terribly difficult.
I have tried several times but somehow I can't figure out the right way to defeat this boss:| any tips?
The main, of many, problems with this guide is the label on the titles. Yes, it`s Canada. But, where in Canada? Vancouver! What a surprise!! Seriously, more attention to detail and a lot less sloppyness, Mr. Seid. For Example, Cerberus base mission...ok, well ,um which of hundreds of planets was that?
I just watched two of the new ending cinematics, there are now four major endings. Apparently it is now possible to choose badly enough to lose the entire war against the Reapers. Try it, choose all Renegade responses at the end and watch what happens.
Great guide, fail to see everyone's problem with the ending, you defeat the Reapers and get a life, the end
@wavelength121 DUH, there are no clear details, just generalized findings. Completely unprofessional.
its there anyway to hide these commens, they are longer than the guide pages. It makes the pages load alot slower with extra stuff i dont even want
When dealing with the 2 brutes and the marauders just before finding General Victus on Menae (Palaven's moon), there is a reaper blackstar heavy weapon located on the right hand side of the map for you to use. So use it!! On insanity, it becomes a necessity!
@Dead_Locked795 this was, by far, the most helpful suggestion. Thanks! Too bad this guide was not even close to that. What a waste of space, and this fool gets paid to give mediocre advice.
How come the Table of Contents only goes up to Geth Dreadnaught? That's the exact point I'm at in the game, and the only reason I looked at this guide was to see how many missions I have left to get to this terrible terrible ending I keep hearing about!
@ali0918: Are you mad? The ME series is one of the few true eletronic roleplaying games we have. Yes, RPG stands for roleplaying game. In Mass Effect series: - Roleplaying? Check. I don't know much games that gives me so many choices about what kind of character I want to be with so many ways to demonstrate it. - Does your choices make difference? While most eletronic "RPG" we see out there gives you choices but they simply doesn't matter at the end, in ME your choices actually shapes and changes the world around you, and also what you'll have to do to accomplish some objectives. So this game is not rpg? You either have got to be kidding me or you simply doesn't know the meaning of the acronym.
NEW ITEM PICKUP: after entering the broken airlock and taking out the Cerb punks, turn around to the left and look around the sink to find a SMG Scope upgrade.
Your After Geth Dreadnought scans are the same as your After Sur'Kesh. You should really take a look at that!
@tex242 Yeah, some having to be completed before you embark on your next big mission ot they'll be gone. A shame the strategy guide didn't tell me that in the first few pages....
also for the record people who are saying they didnt get the special ending yet who did multi you need to have between 4-5k war assets forget which it is
in case GS forgot to mention it in their walk through... make sure you do multiplayer and get 100% war readiness... that will allow you to CHOSE the GREEN light which is BY FAR the Prettiest of the 3
[spoiler] Renegade Interrupt: kill Kai Leng, Don't press Renegade Interrupt: Kill Kai Leng. CHOICE! [/spoiler]
OKK ME MY SELF DONT CARE IF IT WAS GOOD OR BAD ENDING BUT I WISH FOR BIOWARE TO GET US NEXT TIME A ONE DECIDED ENDING, AT LEAST THE ENDING, SO WE COULD REST IN PEACE
Everyone complains about the ending saying that is wreaks the game completely. I think that yes, the ending was quite disappointing, but it didn't erase the fun I had getting up to that point. It is still a good, fun and powerful game I had a really good time with. In my opinion it's the journey not the destination.
@djforlife84 You are so right, god forbid we ask for quality for the price they demand. It is also so unreasonable and selfish to ask them to live upto the promises they made pre-launch. You have made me realize the error of my ways and from now on I will accept the pile of crap they give me, and will even smile and thank them, because we all know we got where we are today by accepting everything as-is.
Just for laughs...what will ending a beloved series the way Bioware did in future be called? Pulling a Bioware? Pulling a Hudson? Embracing Enternity? ?
Let me see... -Blue explosion or -Green explosion or -Red explosion decisions...decisions...decisions
@djforlife84 100% agree with you. I hope bioware doesn't alter the ending in the slightest. Sometimes gamers look like 3 year old kids who enrage for a bag of crisps or candy.
@ag_04 @djforlife84 you sound like retirees being told what to accept and having no choice but to accept it. `Off to the retirement home for you sailor, and no, you have no say in the matter because we know what`s right! for you`... LMFAO, I rather be a child that fights for his rights than a fool that gets herded to nowhere. Really, think about. They`re abusing your rights as a consumer and you just take it. WEAK.
P.S. I played all 3 games with same character. With all DLC installed. I actually played them in a roe... in the month before ME3... so do not dare telling me i don't understand what ME is. Thank you.
@djforlife84 i totally agree with you. Some opinions are so puerile. I actually loved the ending. Seeing Joker and EDI made Shepard's sacrifice (if he really did die) worthy. I hate the ending because it doesn't give me more details. What happened next. What happened to Shepard and the others... But there are ways to explain all these later... just keep the hope burning. These Stop Koni, Stop Acta kids now want to change a game ending!? What next... petition Tolkien to bring Boromir back to life?
@CornelMosneag Really, your comparing a literary work of art to a commercial sell out. Do you even know the difference? Obviously not.
