Prologue: Earth1) The game would start with Shepard exploring Vancouver and meeting/talking with Vega and Colds.
2) Anderson takes Shepard to his tribunal and they run into Ashley/Kaiden on their way there.
3) The Tribunal is basically an opportunity for players to get a recap of the things that they did in ME2 mainly:
a) Being brought back from the dead via the Lazarus Project

Working alongside Cerberus, a known pro-human terrorist organization
c) The Collector Base Run
d) The events of Arrival
Shepard can take multiple approaches here, he can either take the paragon route and be fully willing to take responsibility for his actions despite the fact that it was the right thing to do. Or, he can go renegade and defend his actions by pointing out everyone else's gross inaction including the ignorance of Sovereign's 3 year old corpse.
Former crew members like engineer Adams, Dr. Chakwas, Joker and even Anderson defend Shepard via hologram or in person.
Just as the Tribunal is about to make their verdict, the reapers attack and everything plays out largely the same as in the vanilla game from there.
Priority: MarsEverything stays the same except cut out that stupid chase scene and Ashley/Kaiden being hospitalized.
Ashley/Kaiden and Liara join the Squad
Priority: Eden PrimeYep, I'm counting the Day 1 DLC pack as part of the vanilla story like it should've been.
The squad unloads on Eden Prime to search for a beacon that Liara found additional info on Mars about. They search around it turns out to be a frozen Prothean and the crew activates the mechanism to wake him up.
Aboard, Javik melds his mind with Shepard's and learns about everything that's happening in this cycle. Javik himself knows nothing about the Crucible, but he was aware of a beacon that holds something called the Catalyst.
Javik joins the Squad.
Priority: Citadel IThe same except Ashley/Kaiden isn't in the hospital and you can have a genuine one-on-one talk with them about your friendship/relationship since Horizon.
Paragon: Acknowledge their feelings and emphasize a desire/need to move on and patch things up. Convo ends on an optimistic note with Shepard pretty much viewing the situation as water on the grass.
Renegade: Harshly reprimand them for Horizon and for still distrusting you after everything that you've been throught. Convo ends on a sour note with Shepard saying that they'll have to earn your trust.
The Council is as unhelpful as always and Shepard can accept this (Paragon) or say "ah yes reapers" (Renegade). Javik pretty tells them that they suck and that he won't comfort a hiding dog.
Vega joins the Squad.
Priority: PalavenSame as the vanilla.
Garrus and Edi join the Squad
From here, players can choose any Priority in whatever order that they desire. After going through two main missions, the Second Citadel mission is unlocked and Thessia is available after that. You won't have to complete every priority, but it would be highly recommended for maximum war asset utilization.
Priority: Tuchunka ArcLargely the same as vanilla.
Padok Wiks joins the squad (He'll try to kill you later if you sabotaged the Genophage. Have fun!)
Priority: Rannoch ArcLargely the same as vanilla.
Tali joins the Squad (If you sided with the quarians or brought peace between geth and quarians)
Priority: Grissom Academy (Unavailable after Citadel II)Largely the same except...
Jack joins the Squad (If she's loyal and Jacob survived and is loyal too)
Priority: Citadel IIAshley/Kaiden and Javik will be required companions for this one.
Miranda is found in a standoff with a bunch of Cerberus soldiers and Shepard goes to help while sending Ashley/Kaiden ahead to find the council. Miranda becomes a teammate with skills largely similar to her role in ME2.
Kai Leng battle no longer as contrived or on the rails. Shepard will now have an opportunity to properly fight and defeat KL and outright kill him if he takes the Renegade prompt. Otherwise, a heavily wounded KL will flee with his tail between his butt.
Udina showdown is now between Udina holding the council hostage and Kaiden/Ashley telling them to stand down. Shepard can either encourage a paragon approach or outright tell them to shoot Udina. Either way, Udina ends up dead by suicide, getting shot by Kaiden/Ashley or getting shot by Shepard...multiple times if renegade.
Javik melds minds with the Council to ensure that none of them are indoctrinated and discovers that the asari councilor knows about the catalyst. She confesses that the asari have a prothean beacon on Thessia and the other council members are obviously pissed. Shepard can convince them to hold off the councilor's trial until after the reapers are dealt with (Paragon) or he can punch her and tell her to get out of his sight (Renegade)
Miranda joins the squad (If she's loyal and you promised to help her find her sister)
Thane joins the squad (If he's loyal and he didn't get mortally wounded by KL)
Priority: Rachni planetLargely the same
Grunt joins the squad (If he's loyal, survived the suicide mission and the Rachni Queen was saved)
Priority: ThessiaSomewhat the same except KL can be legitimately killed here...though he'll be more difficult to beat. But the gunship can be fought and destroyed.
Vendetta is retrieved, but it runs out of power while the reaper main force invades Thessia.
Defeat in Victory...
In the aftermath, everyone's still depressed because Vendetta is useless to find the Catalyst. Liara and Javik still have their argument the same as it was in the vanilla version. Shepard can either encourage everyone not to give up hope (paragon) or he can tell them to shut up and move on to finishing the fight (renegade)
Priority: HorizonMiranda tips Shepard off on an incomplete prothean beacon located on Horizon. Events play out largely the same except no KL, but Miranda can still be killed when confronting her father if she's not loyal or Shepard is proactive enough in diffusing the situation.
Priority: OmegaLargely the same except Shepard can potentially kill Aria towards the end.
Priority: LeviathanLargely the same except for the origin story of the leviathan empire.
Once they gained their empire, several thrall species started utilizing dark energy to advance themselves in revolt. In response, several leviathans willingly broke themselves down into the first reaper, Harbinger. Harbinger wipes out the leviathan empire and the thralls and converts them into a dozen reapers including Sovereign. The leviathans have no explanation for why Harbinger betrayed them nor why he initiated the cycles.
After completing two missions post-Horizon, Vendetta will be charged enough to tell about the Catalyst. However, the Citadel will be attacked by the reapers and Shepard will be contacted by the frantic council. Shepard can either comfort them and promise to protect the galaxy (paragon) or go through the "Ah yes, reapers" routine and rub their faces in how their fate is their own fault (renegade) or cut off the transmission prematurely.
Priority: Cerberus HQEither for revenge (renegade) or to remove a thorn in the galactic side (paragon), Shepard launches an assault on the Cerberus HQ.
Inside, Shepard faces off against a reaper-altered clone of himself that the Illusive man had made during the Lazerus Project. Shepard fights the clone alone while his squad downloads any reaper related information from the Illusive Man's computer.
At the end of the fight, Shepard can either allow the clone to die peacefully and acknowledge it's sentience (paragon) or Shep can brutally torture and kill the clone while mocking it. The Data highlights the existence of a mass relay replica within the Citadel which reminds Shepard of Ilos and the Conduit.
Point of No Return.Priority: IlosShepard, Hackett and Anderson form a plan to board the Citadel that's now orbiting Earth. Shepard will take a small fleet to Ilos to secure the Conduit and send Hammerteam through it to directly access the Citadel from within. Hackett will have the Victory Fleet assault the reapers amassing around the Citadel while Shepard goes through the Conduit.
On Ilos, it turns out that Cerberus was trying to destroy it per the reapers orders and Shepard will be on a time limit to stop them and defuse the timers. Once the Conduit is secured, reaper reinforcements are spotted and Shepard must choose a platoon to stay behind and detonate the Conduit.
That platoon will have to be led by a current or former squadmate.
Whoever is chosen to lead will have a final conversation with Shepard and the gang. Then there will be a cutscene that will either confirm their death (if war asset count was low or they weren't loyal) or will leave it ambiguous before the conduit is detonated.
Priority: Citadel IIIHammerteam arrives within the Citadel and their success will vary:
If overall war asset count was low, they'll be decimated since the Victory Fleet was destroyed within minutes and Shepard dies right then and there.
Moderate Count, they'll take heavy damage but Shepard still manages to open the doors of the Citadel.
High Count, low to moderate damage and Shepard won't have as many enemies to fight on his way to the Citadel door controls.
Then...Harbinger appears. Shepard and Harby have a good ol' chat where Harbinger acknowledges Shepard's efforts and indirectly states that Shepard is respected. Shepard can either return the compliment (paragon) or coldly order an artillery unit to deal the first blow (renegade).
As fighting Harbinger on foot will be largely impossible, the outcome will depend on the remaining war asset count:
If too low, Harbinger curbstomps the entire ground force and kills Shepard.
Moderate, Harbinger curbstomps most of the ground force and Shepard is heavily wounded.
High, Harbinger is heavily damaged and half of the ground force remains intact, Shepard loses armor but is otherwise okay.
If he's still alive at this point, Shepard will call for fleet support as Harbinger (now essentially blinded if war asset count is high enough) is reinforced by two destroyer reapers. Shepard and squad use target designators to guide fleet firepower and destroy the two escort reapers. Afterwards, Harbinger attempts to take direct control of the Citadel himself and Shepard's squad is caught within his shield.
While fighting off indoctrination and fatigue, Shepard and the squad make their way through the inside of Harbinger to set up high-grade explosives within his core. If any squadmates are unloyal then they'll turn on Shepard and he'll have to either kill them. Shepard and squad set up and set off the core and Harbinger seemingly dies.
Crucible docks with the Citadel and activates.
End Sequence Begins.Shepard awakens surrounded by his battle scarred and barely conscious squadmates. Still barely alive, Harbinger speaks to Shepard's mind and shows him images of various celestrial anomalies like Maelstrom's star. Harbinger talks to Shepard about the Dark Energy crisis and how the destruction of the reapers will only doom the galaxy.
It turns out that the leviathan empire heavily abused dark energy for just about everything and thrall species only contributed to stand a chance of revolting. Harbinger was created as a means of stabilizing the dark energy within the thrall species since it's energy was far more static and potent. (I don't pretend to understand the full science behind dark energy, so bare with me.)
But Harbinger also saw that over-usage of dark energy was beginning to degrade the stability of the entire galaxy and Harbinger made more reapers to wipe out the leviathans and convert their genetic structure into paste for more reapers. Reapers absorb dark energy and emit an invasive stabilizing variant that builds up over multiple cycles.
Since the development of dark energy is now inevitable, the reapers created the mass relays and the citadel as a means of attracting dark energy potential species to easily advance themselves and then be harvested to solve the overarching crisis.
But...the prothean cycle caused problems, mainly because the protheans themselves could not harvested into reapers for some reason and then the Ilos Scientists screwed up the keeper signal and threw things off schedule by a few thousand or so years. The rachni were indoctrinated by Sovereign in an attempt to correct the problem, but it only led to the lifting up of more species that used dark energy including the turians and in extension, humanity.
Humanity's inherent genetic diversity is the key to a reaper that will finally bring balance to the dark energy crisis and that was why Harbinger sought to create the proto-reaper that Shepard destroyed. The Crucible was a leviathan device create to harness and control the dark energy of the mass relays, but the reapers always managed to stop it's creation since the dark energy that it would emit would potentially exasperate the problem.
His body is crippled, so Harbinger cannot directly stop Shepard and his mind is too strong to quickly indoctrinate (IT aside). But even so, Harbinger implores Shepard to aim the Crucible at Earth...doing so will destroy Earth's livabilty and convert every human into organic paste that is transported into pre-built reaper containment units set into place during the invasion of earth. From these units, the reaper will create a "prime" reaper who will safely stabilize dark energy and end the crisis once and for all.
Shepard can either agree with Harbinger or not agree.
If Shepard agrees then the Crucible will fire on Earth just as Anderson contacts Shepard...
Low War Asset Count: Mass Relays destroyed wiping out most of the galaxy, everyone dies.
Moderate War Asset Count: Mass Relays damaged, Humanity on Earth and throughout the galaxy are wiped out, Shepard dies and crew mourns him, the rest of the galaxy rebuilds, reapers leave and Harbinger dies promising that the reapers will never return unless the crisis should somehow emerge again.
High War Asset Count: Mass Relays lightly damaged, Earth completely depopulated, Shepard and crew live, the rest of the galaxy rebuilds along with the small remnant of humanity, the reapers leave and Harbinger assures that the reapers will never return. The fate of the cycle species is now their own.
Or...
Shepard can pretty decide that the galaxy will solve the crisis on their terms and use the Crucible to destroy the reapers....
Low War Asset Count: Citadel explodes killing everyone aboard, Mass Relays destroyed along with most of the galaxy and the mass emission of dark energy collapses the galaxy onto itself and creates a black hole that starts to spread throughout the universe...
Moderate War Asset Count: Citadel heavily damaged, Shepard dies, Mass Relays damaged, galaxy rebuilds, and everyone works to resolve the crisis without a confirmation on whether they have a chance before it's too late.
High War Asset Count: Citadel moderately damaged, Shepard lives, Mass Relays lightly damaged, galaxy rebuilds and Shepard spearheads the effort to stop the crisis with a high chance of success thanks to data retrieved from multiple reaper corpses including harbinger.
Epilogue:Shepard and LI are shown living together, if you have a high war asset count. Otherwise the LI is left mourning your empty grave.
Current and Former Squadmates from throughout the series are shown in either a bittersweet context (if you have moderate war asset count or lower) or on a happy note (high war asset count)
Your decisions concerning the Krogan and Rannoch Arcs are shown.
Earth's eventual fate is displayed depending on your choices. If humanity is sacrificed, then it's either a barren wasteland (moderate war asset count or lower) or it's a lush jungle world orbited by space colonies. If not then earth will either be a recovering world (moderate war asset count) or a recovered metropolis (high war asset count).
Hackett will either be standing alone (If humanity is sacrificed) or Anderson will join him and he/they will discuss Shepard's actions and their consequences.
The Council will have expanded now including the geth and/or quarians; the krogan (if the genophage was cured and Eve survived); and Javik. The previous Asari Councilor will have retired and replaced by another influential and respected matriarch (If Shepard choose the paragon option during Citadel II) or the Asari councilor replacement will sit quietly and largely be ignored. If humanity was not sacrificed then Anderson will be the Alliance Councilor and if it was then Hackett will be the Councilor.
Joker and EDI will search for his family with two possibilities: A) He finds out that they're dead and EDI comforts him (Moderate war asset count) or

He reunites with his sister and father and EDI is introduced with warm reception.
The Mass Relays will be repaired and used in the same capacity as they were before (moderate war asset count) or They'll be used as a basis for creating alternate means of teleportation.
If your war asset count was high (6000+) and humanity was sacrificed...Shepard will once again be entering a trial for his actions. His LI will kiss him and every crew member and squadmate past and present will be walking alongside him. Whatever the Council's verdict, they will face it together.
"You go, we go."
If you have a decently high war asset count (+7000) and destroyed the reapers, then we'll see a scene of Shepard boarding the Normandy followed by your LI, Joker, and the squadmate who you've used the most in the entire ME series (or just ME3 for simplicity). After that, every single crew member and squadmate from past games will board the Normandy and they'll fly off on one more adventure.
"Second star to the right and straight on 'til morning."
