Mass Effect 3 Spoilers Ahead!

The Best Weapons (And How To Get Them)

NOTE: All guns are dependent on class / species. These weapons might not best fit your play-style, but online players have come together and agreed that the Geth Plasma Shotgun is indeed the Holy Grail of ME3 weaponry.

Geth Plasma Shotgun:

  1. THE BEST WEAPON. Seriously. Ignore that Rocket Launcher, just use this sucker. Effective at even long-range once fully charged.
  2. To get this gun online, you’ll need to purchase the Veteran Pack and cross your fingers.
  3. Offline, you can pick this one up during the Priority: Rannoch mission, or purchase in one of the Citadel stores afterwards.
  4. To effectively use this destructive platform, hold down the fire button to charge it’s shots, then let loose to kill anything in your way.

M-6 Carnifex:

  1. A tiny sniper rifle. Perfect for popping heads at close or long-range.
  2. Online, this is another weapon picked up from the Veteran Pack, dropped randomly.
  3. Offline this magnum pistol can be found during the Arrae: Ex-Cerberus Scientists side-quest.

Black Widow:

  1. Used by a Quarian Adept or Vanguard, this weapon is absolutely devastating.
  2. You can only get this one from the Spectre Pack, so save your credits and pray.
  3. Pick this baby up offline at the Spectre Requisitions terminal in the Spectre Office, at the Citadel Embassies. You’re going to need 200,000+ credits to get your grubby mitts on this massive gun.

Scorpion Pistol (Contributed by Donpiton in the comments!)

  1. This handheld monstrosity fires explosive sticky-explosives that adhere to enemies and surfaces before popping for a good amount of damage. It isn’t like other pistols, it’s very slow to fire, and the round won’t explode for a few moments after landing.
  2. But, this weapon is perfect against small clusters of enemies. It’s the only pistol that can significantly damage Brutes or Atlas Mechs, and it’s a great way to lay traps or hit enemies behind cover. It can also damage pesky Cerberus soldiers using shields — just fire an explosive shot to their left or right, behind their shield, to inflict damage.
  3. In the game proper, you’ll pick up this pistol during your mission on the Salarian Homeworld Sur’Kesh. You won’t miss it!

M-37 Falcon

  1. This unique Assault Rifle fires bouncing grenades instead of bullets. While unwieldy and slightly difficult to hit enemies with, it’s very accurate and very powerful. You can drop grenades behind cover, or use it as a direct-fire weapon as the grenades explode in contact with enemies.
  2. The low magazine-size is one drawback, but so is the aiming. To land a hit, you must hit the enemy dead-on or the shot will harmlessly fly off. For a Sniper Rifle or Pistol, that isn’t a hard pill to swallow. But for an Assault Rifle, you’ll have to learn to be patient and carefully aim your shots.
  3. You’ll acquire this gun only at the very end of the game — during the mission to Cerberus HQ.

I think you the scorpion is the best pistol. The rounds are slow but when they make contact the damage is clear. Its the only pistol that does work on enemies like atlas/brutes. Also it can take out a few enemies at once if they are grouped together. It’s basically a mini sticky grenade laucher.


On March 10, 2012 at 10:11 pm

The Scorpion’s projectiles are much too slow to be good.

The M-37 Falcon definitely deserves its place there, if it wasn’t for the superlate pick up. If you’ve played BF/COD, it’s basically analogous to the infamous noobtubes. Seriously, it requires very little effort to use. Even against the raw damage of the M-99 Saber, the amount of utility the Falcon has is astounding. No more waiting for that chump behind thick cover to come out. Just place your shots next to him and he’s a goner in 2-3 shots.

I started Mass Effect 3 on Insanity, and have beaten it 3 times already. The Falcon is borderline OP, if it weren’t for the limited rounds per thermal clip (4 stock, 7 with EMags V).

Arch Pistol needs some mention, i mean charge that bad boy up and your popping heads of any enemy without shields


On March 12, 2012 at 2:53 pm

One word, Javelin.
It’s ability to shoot and look through walls is very handy sinds units in cover tend not to move much, thus making headshots easy.
And it shoots through multiple enemies, so if you time wel, you can shoot 2 canibals or so in 1 shot.Also the chakram launcher needs to be on this page, it’s a flipping beast.


On March 14, 2012 at 12:54 pm

My only real problem with the synopsis above is saying only the Scorpion can damage Brutes and Atlas mechs. That is so completely untrue, as I can damage/destroy both/either destroy with any weapon I choose. Please don’t make such outlanding claims because people who have yet to play the game may actually believe those wild claims.


On March 14, 2012 at 1:59 pm

Hey Tru,

I think you’re taking the statement too literally. Of course any weapon will do damage to Atlas Mechs, anyone that plays the game will know that! But, if you want a pistol that can actually significantly harm a tough enemy like that, the description isn’t wrong.


On March 14, 2012 at 6:39 pm

I did the mission on surkesh but did not find the pistol….


On March 14, 2012 at 6:53 pm

Ok i keep seeing these boxes that get a glare ever couple of seconds, it wouldnt be glaring if it wasnt something special. But i walk up to it and it doesnt show up any options like press a to pick up something, could it be because my difficulty is on easy? What are these glaring crates?? Feel free to message me on xbox GT is icyhot1995


On March 15, 2012 at 7:33 am

Hello Icyhot1995,

The Scorpion pistol is found in a corner near the power-switch you have to hit to progress through the mission where you’re trying to rescue the Female Krogan.

I just wanted to point out that the M-77 Paladin is basically an upgraded version of the Carnifex. Other than that, the list looks fine – Geth Plasma Shotgun, Black Widow and the Paladin seem to be the best performers all in all.


On March 21, 2012 at 3:53 am

For me the best Assault rifle by far is the Geth Rifle.
With a clip booster and a scope – with armour piercing ammo it will happily shred complete waves of enemies on a single clip.

If you are getting swarmed switch to an ammo with a disabling function like disruptor or cryo – and you have a crowd control beast of a gun.

As for Snipers – Paladin FTW – not only the most powerful, but the scope is useful


On March 21, 2012 at 10:15 pm

I think the scorpion by far is the best pistol . For a real power boost just put some cryo ammo on it and bobs your uncle. It freezess almost instantly and boom littel pieces all over the place those with no armor and those that do it stills slows them down. Which is ripe for a melee smack down. Or if your a vanguard bio charge and its all over. Also I like the turian automatic riffel rate of fire is better the your smgs and the accuratcy is insane. And if you get it up graded during the second play through slices though reapers like a knife though hot butter. And once agian cryo ammo its a wrap


On March 24, 2012 at 7:39 am

Finished my play through on insane, arc pistol is the only gun i use (im an adept as usual) should be upgraded because of the weight, but its powerful and versatile. Charge it up to get the same power, or damn near as the paladin/carnifex, otherwise its fire rate is probably the fastest of the heavy pistols. The only real draw back is the weight, but once up graded its 200%, has a big capacity too. As for multiplayer i think they nerfed it a little and increased the weight, but oddly enough i find that im in love with the locust/temptest for my adepts, i always assumed the smgs sucked, but i was wrong.

Geth assault rifle and Javelin sniper rifle, no doubt. Not only is the Geth assault rifle the fastest weapon in the game, if you use marksman + fit it with damage modifiers, it will rip through even an atlas in a single clip. Gigantic rate of fire.

As for the Javelin… Shoots through walls and even metal objects, massive damage. Need I say more?

Then there is the Krogan nailgun. 95% of enemies will be 1-hit once this weapon is fully upgraded to level V and fitted with damage perks.


On May 24, 2012 at 3:00 pm

Has nobody used the M99 Saber?
It’s very heavy, and fires half as fast as the Mattock, but it does HUGE damage. It also has a ton of spare ammo, so I don’t bring a second gun.
One headshot kills most troops. I usually solo Brutes and Atlas’, and huge damage to Banshees. Beast Mode.


On June 4, 2012 at 8:35 am

While I don’t disagree that these weapons are great the Talon is my gun of choice in mp. This little beauty cuts through armor like nobody’s business.


On July 19, 2012 at 2:27 am

Is anyone going to say anything about the Phalanx?
Then I will: I’ve just finished a playthrough on Insanity, and it’s pretty much the only gun I use.

Also, the Javelin needs to be on there.

you 4got the [particle rifle as it can not grt out of bullets and rate of fire is so very good.. only if you dont empty the whole chaarge.. it recharges pretty fast..


On August 7, 2012 at 7:51 pm

guys cerb harrier!?!?!?! if you havent used it you must have seen it that with the stability mod and penetration you can cut through 4-5 guys in one clip if you aim for chests, kills two guardians in a clip toasts brutes in 3-4 clips only problem is ammo consumption but with the new supply pilon that isnt an issue


On March 3, 2013 at 5:26 am

The paladin is easily the best pistol

M-96 Mattock

The Mattock because of it’s obvious firepower, which is comparable to a sniper rifle and the rate of fire is only limited by how quickly you can pull the trigger. While the clip size is limited only to 16 rounds, when fully upgraded and modded with Incendiary or AP ammo, Atlas Mechs or Reaper Brutes… Even Reaper Harvesters melt down easily. Close, mid or long range – The Mattock is a must-have for any Spectre out there.

M-97 Viper.

High firepower, a clip size of 5 rounds and very stable. When fully upgraded and modded with AP or Incendiary ammo, it swiftly decapitates any shielded infantry unit with a single headshot. Very handy for Soldier classes, looking to mow down as many opponents as possible, before their Adrenaline Rush wears off.

Both of these weapons are the must-have hardware for Soldier classes. If both are upgraded, their weight will decrease the cooldown of your abilities, allowing the Soldier to wreak even more havoc on the battlefield with his other abilities.
