Infiltrator build - Mass Effect 3 (ME3)
This post covers the best Infiltrator build in Mass Effect 3 and Mass Effect 3 Legendary Edition. The class is a master of cloaking and technical powers. It is well-suited to be used with Snipers for a single, deadly shot
The build is for those that wish to master the Sniper Rifle. We will use Tactical Cloak to conceal the infiltrator position and strike enemies for maximum damage from where they do not expect. Moreover, we will be using Technical abilities to drain enemy shields and create blast combos.
Squad Point Allocation
This section covers how Squad points should be allocated for the end game on the Infiltrator Build
|Power name||Upgrades Order||Level (Points)|
|Operational Mastery||Weapon Damage
Unfortunately, I forgo Cryo Ammo. It is not a bad ability, but I find it lackluster on Insanity difficulty. However, on lower ones, this is a perfect choice. My logic is that, once you reach enemy health, either they will be killed in the next shot or it will be a combo detonator. So to waste time, to shoot additional time, just to freeze greatly decreases the combat tempo.
I also skip Sabotage. Although it is a good skill, the lag effect, and mediocre damage does not make it a compelling choice against human enemies. It can be effective in particular scenarios but I prefer to be in control when the effect activates.
Here I will cover what bonus abilities you should pick with the Infiltrator class.
|Power name||Upgrades order||Description|
|This skill is a perfect combo with Disruptor Ammo. You can use it to detonate Tech Bursts or remove enemy shields and increase your own. It unlocks numerous possibilities for Infiltrator build|
Accuracy & Firing Rate
|If you wish to concentrate on pure damage and less on Tech abilities, take this skill. It will greatly improve fire rate, allowing to shoot down enemies on after another.|
This section covers detailed ability progression for Infiltrator Build. This is just a suggested progression, feel free to adjust it based on your needs.
|1||Tactical Cloak Lv 3||This ability will be extremely helpful early in the game. Use it to hide from enemies and increase your damage with the first shot.|
|2||Sticky Grenade Lv 2||Deals a large amount of damage. I always recommend having a few grenades if the encounter becomes difficult.|
|3||Incinerate Lv 3||This is your main ability in dealing with enemies that have Armor protection. For the maximum amount of damage, try to use it with primed enemies for Tech or Fire Bursts.|
|4||Disruptor Ammo Lv 3||Now this will greatly unlock the capabilities of Infiltrator. The ammo power deals heavy damage against shields and barriers. Moreover, it primes the enemies of Tech Bursts. Use it together with Energy Drain or Incinerate for deadly combos.|
|5||Operational Mastery Lv 3||Provides some small bonuses - weapon time dilation, increased weight capacity, etc.|
At this stage, I recommend getting your preferred Bonus Power. If you rely heavily on Tech powers, go for Energy Drain. Otherwise, feel free to pick other ones.
|6||Energy Drain Lv 3 (if you choose Energy Drain)||It is a definite choice for detonating Tech Bursts or setting them up. It is especially useful against Synthetic enemies and will increase Infiltrator survivability|
|7||Incinerate Lv 5||Take Damage upgrade. Unfortunately, Infiltrator is fairly weak against armor, and you want to make sure that your abilities tear them down as much as possible against a single enemy. The second upgrade should be Recharge Speed.|
|8||Disruptor Ammo Lv 4||Take Damage upgrade. This will further boost damage against health, barriers, and shields.|
|9||Tactical Cloak Lv 6||Take Damage, Recharge Speed , and Bonus Power upgrades. Once you get the three upgrades, you can include abilities into the rotation without revealing yourself.|
|10||Fitness Lv 3||Getting a few levels in this passive skill it will give bonus defenses and health.|
|11||Incinerate Lv 6||Get an Armor Damage upgrade. This way Infiltrator build will have a way to deal decent damage against armor. Be sure to pair it with something like Overload for Fire Explosion combo.|
|12||Energy Drain Lv 6||Take Damage, Recharge Speed, and Damage upgrades. With these choices, the ability can take out normal enemy shields instantly. You can also go for a Radius upgrade on the 4th level and it is a good choice, especially if you have your sniper rifle upgraded for more damage, and a bit of shield left doesn't need an additional shot.|
|13||Operational Mastery Lv 5||Take Weapon Damage and Weight Capacity upgrades. This will improve Infiltrator build offensive capabilities - your skills and shots will deal more damage. Moreover, thanks to its larger weight capacity Shepard can have lower cooldowns on abilities.|
|14||Disruptor Ammo Lv 6||The build goes all in on the damage - take Headshots and Damage upgrades. This will give maximum effectiveness against shields and barriers and provides the highest chance to prime Tech Bursts.|
|15||Sticky Grenade Lv 4||Any upgrade works, I prefer Damage. This is the perfect grenade ability for Infiltrator as it is extremely effective against armored enemies|
|16||Operational Mastery Lv 6||To be honest, any upgrade works. At this stage of the game, you should have your preferred playstyle. If you rely more on weapons - take the Sniper Damage upgrade. If you use your powers more go with Damage & Duration for high powers bonuses.|
|17||Sticky Grenade Lv 6||Take Armor-Piercing and any upgrade for the 6th level. The idea is to have a tool against Armor, the last two tiers just fit different playstyles.|
|18||Fitness Lv 6||We go all in on the defensive abilities - Durability, Shield Recharge, and Durability. Nothing special here, just gives a bit more survivability for Infiltrator|
Tactics and Squad
This section will cover how to best play Infiltrator build in Mass Effect 3. The class can be played as easily as just shooting with Sniper Rifle, or creating multiple combos to incapacitate enemies on the battlefield.
This is the first ability that you should learn with Infiltrator. It has multiple use cases, but the one that is most obvious is positioning yourself on the battlefield. Once that is done, you can shoot with Sniper Rifle for maximum damage or use abilities to debilitate enemies.
Of course, in case you are overwhelmed, just hide behind a cover and activate it. Then feel free to move further away, where you can snipe enemies. Enemies may still shoot you when you activate Tactical Cloak without cover.
Moreover, this ability is perfect with Sticky Grenade as when used it does not break stealth.
Fighting normal protected enemies
If you fight a normal protected enemy (shield), not a boss type, I suggest using this rotation: Energy Drain -> Headshot. I found it to best work on multiple testing and this does not require any difficult combinations
You can also include Tactical Cloak for even higher damage once you get it to level 6 and fully upgrade it. Of course, if you are fighting stronger enemies I would go with a different combination
- Shoot the enemy and prime for Tech Burst. You need to have Disruptor Ammo activated.
- Use detonator ability, Incinerate or Energy Drain
- Shoot again, and prime once more with Tech Burst.
- This time use one of the companions' abilities - Overload, Incinerate, etc and create Tech Burst.
In case the enemy still has Barrier/Shields use the rotation again.
Sprinkle in some Tactical Cloak and your headshots will do even more damage. Infiltrator is a perfect class for dealing with enemy Barriers and Shields
For this build to work perfectly, you need to have these things in mind:
- Have someone that can easily tear down and damage enemy armor
- Has Tech abilities to detonate or prime Tech Bursts.
Based on the criteria here are my recommendations:
- EDI - she has Overload and Incinerate skills. Combine these with Infiltrator abilities and you can create constant Tech Bursts and Fire Explosions.
- James - he is extremely powerful against armor. This makes him a perfect combo together with Infiltrator. Thanks to Incendiary Ammo you can use Incinerate to create Fire Explosions
- Garrus and Ashley - are the most overpowered companions that you can use to cheese through the game. Let them tear enemies apart as you shoot from far away.
- I would like to also mention Liara. Although she uses biotic abilities, she has Warp. This ability can detonate both Tech Bursts and Fire explosions. Moreover, she has fast cooldowns.
This section will cover what equipment you should be using with Infiltrator Build.
|Black Widow||Spare Thermal Clip
|The improved version of the M-98 Widow. Of course, it sacrifices damage but has a higher ammo capacity. Headshots will take out most normal enemies instantly. It also has armor penetration.|
|M-97 Viper||Concentration Mod
|I love this one. It does not do high damage, but it is perfect for priming Tech Bursts with Disruptor Ammo. Use it on Synthetic heavy missions like Geth.|
I personally do not recommend them for this build. The problem with them is that they would take multiple shots to prime Tech Bursts with Disruptor Ammo. Of course, with some practice, this could work well. However, here are a few options that you could try
|M-12 Locust||Ultralight Materials
|Accurate submachine gun, that you can shoot accurately with full auto.|
|M-9 Tempest||Ultralight Materials
|Has a high ammo capacity and is perfect for suppressive fire. However, it can be difficult to control due to high recoil.|
These weapons are a good choice as a sidearm. They do good damage and have a higher chance to prime Tech Bursts. Moreover, they have mod to improve power damage, so it is a perfect choice in case you run out of ammo with Sniper Rifle.
|M-77 Paladin||Magazine Upgrade
|A high-tier weapon that deals high damage. It is also lightweight and has a low impact on power cooldown.|
|A chargeable weapon that is also perfect for applying ammo effects instantly|
I recommend these armor sets for Infiltrator Build in Mass Effect 3. We want as high weapon damage as possible so that Sniper Rifles would deal maximum damage
|Cerberus Armor||+10% Ammo Capacity
+20% Weapon Damage
|Cerberus Nightmare Armor||+20% Ammo Capacity
+20% Headshot Damage
+20% Weapon Damage
+10% Shield Regen Speed
If you wish to go with separate parts. Here is what I recommend:
|Helmet||Kuwashii Visor||Increases weapon damage by 5% and headshot damage by 10%|
|Helmet||Recon Hood||Increases weapon damage by 10%|
|Helmet||Delumcore Overlay||Increases headshot damage by 5%
Increases weapon damage by 10%
|Chest||Hahne-Kedar||Increase weapon damage by 10%|
|Shoulders||rmax Arsenal||Increase weapon damage by 5%
Increase headshot damage by 10%
|Shoulders||Hahne-Kedar||Increase weapon damage by 10%|
|Arms||Armax Arsenal||Increase weapon damage by 5%
Increase headshot damage by 10%
|Arms||Hahne-Kedar||Increase weapon damage by 10%|
|Legs||Hahne-Kedar||Increase weapon damage by 10%|

I really like your Infiltrator build using it on my male play thougth
Glad to hear that!
I’m pretty much running the same build, but I’ve found the salarian heavy pistol with the exploding ammo is by far the most powerful, especially against more powerful enemies, although it is a little op and takes away from gameplay at times, so I’ve switched back to the spectre heavy pistol, as you’ve suggested
Yeah that is also a good option, I will think about adding this one to the suggested weapons :)
I think you severely underrating cryo ammo. If you want to know how to use cryo ammo read this guide https://bsn.boards.net/thread/19173/me3-cryo-ammo-guide and you’ll freeze everything.
Hey, I tested the Cryo ammo build and read this article, when creating Infiltrator build. I agree with it partially, Cryo Ammo is the best squad ammo.
However, as much as I wanted to like it as primary ammo power it paled to Disruptor Ammo, especially on Insanity.
Did you test Cryo yourself?
Generally, the wait time of 1.7 seconds for the enemy to get frozen really slows down everything. So the combat flow is this:
use ability/shoot enemy (strips protection)
enemy is chilled but not yet frozen and without protection
shoot enemy again to get them frozen
wait for the freeze 1.7 seconds
use ability for Cryo detonation
While you can just do:
Strip enemy of protection (with ability or single shot)
use second shot or detonator ability for combo
I hope you see the difference here, and how much faster you can be with Shepard in taking out enemies. Of course this may differ from enemy to enemy, but generally, it is like this. I also failed to see any other player usecase of this in Insanity difficulty
However, you can use the Squad upgrade of Cryo ammo + Disruptor Ammo. This is when it becomes extremely useful. As you concentrate on an enemy in the meantime your companions can freeze other enemies. Then you just use incinerate to detonate them.
Feel free to join discord, we could have a more detailed talk :) Cheers!
Thanks. Any plans to do mass effect andromeda builds? (yes, i'm one of those freaks who enjoyed the game)
Hey! For now I do not have it planned :/
