I'm on my first playthrough of ME3 with an imported ME2 Shepard Vanguard (level 53).  I'm doing the Priority: Rannoch mission on Insantiy and I'm right near the end, where you go up the elevator and fight the three Geth Primes before the ledge.

However...I don't think this fight is technically possible to win.  As soon as I step out of the elevator, Tali announces to the entire universe that three Geth Primes are in the area, one in front, one to the left, and one to the right, and they IMMEDIATELY start firing at me, taking off all my shields and nearly all my health before I can get to cover.

The cover, however, doesn't last long, since the Primes will continue to move in and constantly spawn turrets near your position.  Despite having myself and Tali with FULLY UPGRADED Energy Drain, and Ashely with FULLY UPGRADED Squad Disruptor Ammo, and using mark V Vinidiator, Carnifex and Mattock with level 3-4 mods, the amount of time it takes to take down the shields of just ONE Prime is so long that we get flanked from all sides.

I've tried drawing the Primes into a clump so as not to get flanked, but the bastards move so fast that they just eventually spread out anyway.

What am I missing here?  How are you supposed to win this fight?  I've had tough fights and have managed to get through the game so far on Insanity without too many problems, but this fight seems to be completely broken.

There are several Spitfire heavy weapons scattered about, one should be right near the entrance. Use Tali's AI hacking a lot and use her drone to distract the primes. Also don't be afraid to spam medigel, its worth it in this fight.

I've only ever done the fight as a soldier so not sure what to say about Vanguard's powers. Shockwave could be useful to stagger them. But yeah, try to stay in cover and be liberal about using the Spitfires. Good luck!

There are a couple of Geth Spitfire chainguns lying around. Those will also help you out immensly, if you can find them.

Also, Tali has Sabotage. Use it to turn the Prime's against eachother. Her drones are also great at distracting them.

Also, I definately wouldn't have taken Ashley on this mission...EDI would have been a fine choice, with Overload to strip their sheilds (and cause tech bursts with Tali's Sabotage) and her Decoy to give them an extra target to shoot at.

I think you're missing Sabotage, you didn't mention it. It works twice on each Prime. Also, Ash? Come on, use Garrus or EDI. Disruptor Ammo + Overload = Tech Boom!

Spitfires + sabotage for instant victory!

Also, combat drones will keep them distracted

Thanks for the prompt replies.

Regarding the Spitfire:

Any attempt to PICK UP the weapon is tantamount to suicide, since I cannot pick it up while in cover and NOT standing in cover guarantees that I'll be killed before I can get back into cover.  Thank BioWare and whoever thought the "one button to rule them all" system would be great for combat. :\\

That being said, I HAVE managed to pick it up on a few attempts, but it's categorically USELESS against shields.  I've had attempts where I've managed to take down the shields of one of the Primes, but the only way I could do this is by leaving the Spitfire behind, and subsequent attempts to acquire it met with death.  Again, this is due to being flanked by the other two Primes and their drones.


Regarding Sabotage:

Since when does hacking work on armored units?!  If this wins me the fight, I'm going to write a very angry post to BW about how unclear so many abilities work in this game.


Regarding Ashley:

Yeah, I'm beginning to think it was a bad idea brining her.  I brought her because I thought the Inferno Grenade would double greatly as an AoE AND as an anti-armor ability (I have the rank 6 that does bonus damage to armor); EDI's Incinerate is single-target only.  I think I might have to go back and replay the mission, but honestly, I shouldn't have this much trouble with Ash.


Regarding Combat Drones:

I have this one maxed out but they don't appear to be that effective.  Can you have more than one out at a time?  I also have Squad Power Usage turned off, so managing the Drones is tedious if I have to do it constantly.


I'll give it another shot with Sabotage.  Seriously, BW, if tihs works, WTF...

Yeah, Sabotage works on Primes. And, shoot the Prime that you've sabotaged. You and the other two Primes pound him until he's dead, then Sabo another and pound him until he is dead, etc.

You always have Tali and she should always have Sabotage spec'd.  You want Tech Vulnerability if you can afford Rank 6, not Berserker.

What I like to do is try to grab the first Spirfire and take cover right as you get off the elevator.  Typically then try to Sabotage the Prime on the right, and then run to the right side.  Shoot the sabotaged Prime in the back with the Spitfire, use whatever appropriate powers, and then Sabotage again if need be.  Then focus the last two in turn.

Basically like this with every class I play:

ARVanguard - Rannoch - 3 Primes.

You'll notice that there is something screwy about the cover sometimes.  I am not sure why sometimes it acts like it won't let me dock (it isn't the stagger either).

Ok, I tried again, and while I'm doing a little better and surviving longer, I'm still not getting anywhere near victory.  I can get, at most, one Prime down to 50% armor and another stripped down to his armor and that's it.  I wasn't shooting my Sabotaged target, as I thought given the ridiculous firepower of the Primes they'd be useful against the others.

However...

Thank you very much for that video.  I had no clue that you could use Sabotage on Shielded targets.  Was there any informational resource in the game that clued you in?  I'm coming from having played ME2 (and ME1 before that) on Veteran / Hardcore, and, IIRC, AI Hacking did NOT work on Shielded or Armored units.  When people said to use Sabotage, I thought they meant AFTER the shields were removed, since Armor is technically used as Health in ME3.

Unlike Mass Effect 2, where most abilities did not work through defenses, Mass Effect 3 allows a bunch of abilities to work through defenses. Sabotage will hack turrets and geth, regardless of defenses.

Also, you are a Vanguard, so you have biotics. Liara should be a permanent squadmate for any biotic character. Her Warp can both detonate biotic explosions (Pull/Singularity/Stasis/Slam/Reave/Shockwave with lift evolution > Warp) and set up biotic explosions (Warp > Reave/Throw/Shockwave/Charge). Warp even will work on shields.

Here is how I did it with Liara and Tali (skip to the 10:00 mark). Not the greatest video, capn233 probably has the better run through that mission.

Thank again to capn233.  I followed your video and managed to complete the mission with little difficulty.

Thanks for the video.  Question: what bonuses do you have from your armor. I have 20% Shield Regen, 20% Power Recharge and 10% Power Damage; there's no way I would have survived that long in the middle of a fire fight as you were doing in the beginning of that video.  Even one enemy unit is capable of stripping my shields and health before I can take three steps, let alone wait for the cooldown on Biotic Charge.

And 99% of the time I take Liara with me, but given the number of shielded units in this fight, I opted for EDI to make use of her Overload.

I don't think you need shield regen if you are a Vanguard. You should have the full barrier restore evolution for Rank 6 of Biotic Charge... and don't go overboard with weapon weight. :)

In any event, while I do agree with Red's suggestion to go with biotic squad members, the tech ones aren't so bad either. You can continually set off tech bursts by charging into Overloaded targets if you want. Not quite as powerful as a biotic explosion (with bonuses) but it will also work decently.

I beat that level without any problems (admitidly, only on hardcore). However, I was Inflitrator, so I just cloaked up, grabbed a Spitfire, then got into cover before the cloak wore off.

I chose the Shield Regen stats because I found that whenever I tried playing the way RedCeasar was playing that I'd have my shields stripped literally within a second (from small arms fire!), so I figured regen would be better to get back into the fight faster and minimize shield downtime, especially with enemies closing in; having more shields just seemed like it would give me an extra 0.25 seconds before it was shot off anyway (on top of the fact I didn't have many +Shield armor pieces).  As a result, I only tend to make use of Biotic Charge to finish off enemies, as using it any other time is suicide.

(And I'm not even going to mention the issue with the UI, which for some odd reason sometimes doesn't let me do a Biotic Charge despite me both aiming at a target and having the ability be available for use).

And yes, I have the full shield restore on Biotic Charge, along with the +Weapon Weight in Assault Mastery to keep the bonus recharge speeds as high as possible.

OP - You are a Vanguard right? 200% simply have 200% cooldown and Charge -> Nova (half-blast is better but full blast can work as well) them constantly, works best when all 3 are surrounding you. They cant hurt you - not even on insanity.

The basic layout of the area is similar to Poseidon's Trident. Focus your fire and squadmates on one particular Prime (I always use Garrus - Overload & Tali's Drone) and after the shields are down, Tali can hack the bastard to give you a hand.

During this time, dodge to the left and right points of the Trident, using the crates as cover. Always keep your hacked Prime and save him for last until all others are gone.

IIRC, in my last (Insanity) playthrough I had EDI (for Overload) and Tali along, and used the Black Widow X and Sabotage to keep one of the Primes from attacking me as I shot holes in the other two. I never left the cover in front of the elevator.

I didn't bother with the Spitfires, requires too much time out of cover to be of any use. I think it took me a good five or six attempts before i managed it.

Then there's that stupid moment that comes soon after that i've spent so many times trying and failing that i've actually just given up on the game. Most of it is easy enough on Insanity, but those one or two moments just made me lose all hope and quit.

I cannot remember what armor bonuses I have. I think it is a combination of melee, health, and weapon damage.

Biotic Charge provides an undocumented damage reduction bonus, something like 40-50% damage reduction for 4 seconds. So after you charge, you take less damage for 4 seconds.

As capn233 points out, you can set off tech bursts with any force or direct damage power, so you can use a squadmate overload > Shockwave/Charge. Tali's Energy Drain can set up tech bursts and depending how you specced her, you can get her Energy Drain cooldown to under 6 seconds. But I find her Sabotage is more useful on Geth missions.

Since the majority of enemies have no form of defenses, Liara's Singularity is instant and has an extremely quick cooldown so you can use that to stop enemies from firing at you.

Take your squadmates and move around using the covers while you shoot at them...

PS: If you don't have overload pick a squadmate that does so turrets are not annoying.
PSS: Or just bring Tali and lolsabotage them.

I just focus on one at a time usually by taking out the middle one first because then you can just run around in circle around the other two afterwards.

Tali's combat drone is kind of useful, but not really. The primes pretty much just destroy those as soon as Tali pops them out. But they can provide a distraction at least, enabling you to move to a different piece of cover.

As for Ashley, what gun(s) does she have? Revenant + Disrupter Ammo + Marksman is pure gold. If you have her primarily using a sniper though, just give her orders to focus on one of the Primes otherwise she'll just kind of fire randomly at each one. She does a lot more if you make her focus on just one.

I didn't know it was possible to hack enemies if they had shields/armour on my first playthrough so I didn't use sabotage on this part either. Nor did I know you could slap warp on a shielded target to set up biotic explosions.

I played as a shotgun vanguard with Tali and Liara on this mission. I initially tried using the cover at the start and grabbing the spitfire but I didn't like having all three primes closing in on me. So I found it was best to charge the prime in the middle then dive in to the cover at that end of the map. Used Tali's combat drone to distract him while Shep used a mixture of energy drain, charge and her shotgun to chip away at him. Its easy to kill the first prime before the others have chance to get to Shep.

Part of the problem is that you are using three weapons on a Vanguard, so your cooldowns are terrible. You have time to sprint to the nearest Spitfire and get to cover, then you can pop out and blast one to give you some breathing (charging) room.

I had a similar issue. Basically, what I did was hide in the cover infront of the elevator the instant I got off. Instant I was in cover, I used Kaidan's Overload on the Geth Prime on the oposite side of the room; the one who could fire upon me, to distract him. As the three primes closed in one my location, I used every ability to harm them as they made their very slow path. Spam abilities the instant the come off cooldown.

Once they came with in distance of me, I charged,Nova'd, and then dodge rolled backward into cover. After that, Just move around the room constantly, spam abilities as they come off cooldown, stay in cover, and use the Medi-gel when you need it as the Rannoch Reaper is a one-hit K.O. Battle so medi-gel is useless there.

Trust me, it takes a load of work, and I barely survived as it is.

After I finished Insanity entirely, I said aloud "I hope you all caught that because I will NOT be doing it again!" lol

Hope that helps.
