Squad Disruptor / Improved Cryo Ammo
The main focus of the Agent Infiltrator is to neutralize multiple enemies as quickly as possible, while killing is a secondary priority. Improved Cryo Ammo
Update on Improved Cryo Ammo. I claimed that ICA has a faster freezing speed, but it was based on a faulty test. Upon further discussion and testing, there is no solid evidence to support this as of now, so in real practical gameplay, ICA's freezing speed is the same as SCA.
Assassination Cloak
There is no advantage in Enhanced Cloak, as you will be mostly using Cloak as a damage booster, and even during CQC, you will rarely ever need the added time to close the distance. If anything, Enhanced Cloak hurts your squadmates since enemies will attack them for a huge chunk of time.
Incinerate
Only one point in this skill Is enough. It is mostly for stopping health regen, the occasional annoying Heavy that’s behind cover, and mostly a final humiliation move.
Agent/Assassin
Agent is the recommended passive for its +15% power duration boost to Cryo Ammo and Flashbang, and somewhat better power CD. It is overall the better choice than Assassin. That said, if you want to focus more as a sniper rifle user, the 60% time dilation may be more beneficial to you, however your rate of killing will be slower at the beginning of the game because won’t be dealing much damage while you're Cloaking less, and throwing less grenades. If you really want to use Assassin, I personally recommend switching to it after Horizon, not before.
Flashbang Grenade
Here is the power that complements the Infiltrator’s inherent abilities and passives so seamlessly. Unlike Dominate, AI Hacking and Neutal Shock, Flashbang works on all enemy types with a very large radius. If Flashbang hits at the right spot, it guarantees either one of two outcomes: A) large amount of enemies staggering or
a large amount of enemies incapacitated. If it’s A), you will have the opportunity to take down their defenses + 1 more shot to freeze, which is much faster than taking down defenses and spending the extra time and bullets to take down that target’s remaining health, so it increases your chance to shoot another target, all in one move. If it’s , then you have already taken control of the battlefield for the next 7 – 10 seconds, doing whatever you feel like. Flashbang + Cryo Ammo guarantees locking down enemies, the freedom to move, more CD time for your squad, and opens up other attack options. If done right, the Agent Infiltrator will rarely be stuck under cover from enemy fire, you will be constantly on the offense and on the move.So, Frag Grenade or Improved Flashbang? If an enemy has 119 shields left, Frag Grenade’s 120 damage will destroy the shield and the target will get knocked down. Frag Grenade also increases the chance to shatter frozen enemies, which is icing on the cake. That said, Improved Flashbang is far more reliable with is massive 9m radius, a very long incapacitate duration, and it also helps detonating crates and containers that are farther. So unless you’re an expert grenade thrower and want to show off, use Improved.
Using the Viper, aka chaining together a series of time dilation
Some shotgun CQC Infiltrators already know this trick. Zoom in, you get 2+ seconds of bullet time, enough to fire off 2-3 Viper shots. Then zoom out and immediately zoom right back in. Another two seconds of bullet time, another opportunity to fire off 2-3 more shots. You can do this forever. If you’re worried abut taking damage, consider that Heightened Arush does exactly the same thing. Because you are also taking damage at a much slower rate, you will have more than enough time to gauge your rate of damage, and more time to assess the situation to decide if you want to shoot or pull back under cover. And because the Viper has 12 shots, you will never need to waste time reloading like you do with the Widow or Mantis. If the Incisor wasn’t so badly designed ammo capacity-wise, I would use that in a heartbeat.
The Mattock
Because your primary weapon will be the Viper, you will not need the Widow, allowing you to use either a shotgun or an assault rifle. If you chose the shotgun, you will primarily be a CQC infltrator, you'll have less opportunities to use Flashbang since you’ll often be in front of people’s faces to begin with. Also with shotgun users, it’s better to choose another powers like ED/Dominate/Neural Shock for their faster CD and instant cast abilities, whereas with Flashbang, you can knock yourself out in close quarters. Like the Viper, the Mattock is extremely effective with Cryo Ammo, guaranteed to freeze a defenseless target with 1 shot 97.454% (sic) of the time. The Mattock is your backup to the Viper, which is not too shabby. It is used when you get closer to enemy lines, and also handy when you do not want to use Flashbang through the scope with the Viper.
Shuriken/Tempest
Because your SR and AR are your primary weapons, your SMG is now used as a dedicated shield and barrier destroyer, specifically against YMIRs, Praetorians, Geth Primes, to conserve ammo, and to go in for some CQC action and cleanup. I’ve done the Overlord DLC pre-Horizon, and tested both the Tempest and Shuriken on the last level where you destroy the VI core’s connector orb things. With only two upgrades, the Shuriken is clearly faster, using only 1 clip of 24 bullets at point blank range, while it took the Tempest almost its entire clip, therefore almost twice the amount of time. That said, the Tempest’s bigger ammo clip may be preferable to players as a safety net, not worrying too much about reloading in middle of a flanking maneuver. And if you're able to get off an entire clip, the Tempest does enormous damage. So either one is good. While the Locust Is a great general-purpose weapon that deal equal amount of damage between shields, barriers and armor and it has high accuracy, it’s a role you’ve already filled with the Viper and the Mattock. Keep in mind that SMGs' chance to freeze is more unpredictable, so you'll need to stay shooting at a target longer to make sure it's really frozen.
Predator/Carniflex
These are really backup weapons, you will rarely use them. But there are some cases where pistols are helpful in conserving ammo, such as the last Scion on the Collector Ship. But generally, the Predator is very versatile while the Carniflex deals fast enough shots to be taken under cloak. The Phalanx is ok, but it’s too slow to get off more than one shot under cloak, if that’s what you’re after.
Attack Method: The Delayed Viper Cloak
As some CQC Infiltrators have already found out, the best time to shoot the Viper is when the time dilation ends, giving you anywhere between 5-6 shots of Cloak bonus damage. To add even more damage on top, do not activate cloak before you aim. During the time dilation, you still have the advantage to shoot off 2-3 rounds, so take them first if it looks good, even try a headshot. Wait for the time dilation to end, and then you activate Cloak to empty the entire clip. Headshots are not a high priority; stripping defense and freezing one or multiple enemies in that timeframe is. The one weakness with this method is when facing against enemies with homing projectiles (heavies, warp from Vanguards and Harbinger, etc). Cloak will not hide their homing abilities, so use the time dilation to assess the situation first. If the enemy is already in motion with casting projectiles, you probably won’t have enough time to shoot and go back in cover without getting hit.
Attack Method: Using Flashbang with Mattock/SMG
if you have the first attack, throw Flashbang to stun and then pop 3-4 shots to each affected enemy to disable defense and /or freeze. Or, if you are under fire, use a squad power to strip defense/stagger/stun, shoot + Flashbang to freeze/knock out. The best time to use it is right before you storm between covers or before turning a corner. Lob a grenade, run for cover, and time it so that the instant it explodes, you pop out and shoot. Take advantage of the environment, bounce grenades around corners, throw them over or around walls and head-high covers before the enemy has a line of sight of you, and then rush in. When using Flashbang with sniper rifles, keep in mind that it will be very hard for you to see where you’re throwing while aiming, so try not to stick to covers when you can, and only stand behind high covers when it’s there.
numotsbane has an excellent guide on using Flashbangs, highly recommended:

II. When the Agent infiltrator is superior
The Agent Infiltrator can deal massive amounts of damage to any tight group of enemies, as well as charging enemies that do not have ranged attacks such as husks, klixens, varrens. Krogans are the easiest to deal with due to their slow speed and using only shotguns. Here are some notable situations where the Agent clearly outperforms the Widow Infiltrator:
- Eclipse attack, Garrus’ recruitment
Move back a bit and spam Flashbang over the balcony before the enemies get a line of sight from you, chain the Viper time dilations to activate squad powers under scope and pick off multiple enemies to freeze. While running for ammo, continue lobbing grenades down the balcony.
- Closing the shutters, Garrus’ recruitment
Flashbang/Cryo Ammo with Viper/Mattock slows down vorchas, varrens, and krogans instead of killing all of them, delaying respawns.
- Initial attack, Stolen Memory
Doors open, a tight group of mercs, perfect for the Viper and Flashbang.
- Initial attack, Jack’s recruitment
Charging armored melee enemies are rendered usless with Viper/Mattock/Cryo Ammo
- Overlord DLC
Squad Disruptor Ammo + Flashbang + Garrus’ Overload = easy
- Horizon
Flashbang takes care of husks, and can be thrown at very long distances. Combined with the Viper’s multiple shots in slo-mo, not many Collectors are actually shooting at you.
- Tali’s recuitment
Squad Disruptor Ammo + Flashbang + Garrus’ Overload = win
- Elevator surprise, Thane’s recruitment
Viper + Squad Disruptor Ammo + Flashbang in tight area = decimated krogan and Engineers
- Dracon Trade Center and Hotel Azure, LotSB
Lots of tightly grouped enemies, especially the trucks
- Grunt’s LM
Hi Klixens; meet my friends Cryo Ammo and Flashbang
- “You talk too much,” Mordin’s LM
- Reaper IFF
Very slow moving husks, meet very large explosion radius
- Legion’s LM
Any knocked out or frozen enemies float in zero G
III. FAQs
Q: What’s the point of shooting a couple of rounds with the Viper if you can just kill in 1 shot with the Widow?
A: Because the OSOK method is not always the best for all circumstances. The majority of the fights are based on you and your squad facing waves of enemies. Some will flank you, and some will spawn more if you do not advance the area fast enough. In the time for the Widow to kill, take cover and reload, I can incapacitate and/or stagger 2 – 3 enemies in conjunction with Cryo Ammo and Flashbang, if not outright killing at least one along the way. Even though I am not OSOK’ing things, I am controlling the battlefield, and because no one is shooting at me, I can shoot back even more, I advance the area faster, and ultimately the rate of kills for me increases exponentially because the more time passes, more enemies are on the ground, unable to attack. Incapacitating enemies instead of killing all of them also helps delay more enemies from spawning, allowing you more time for you and your squad to set up their positions, picking up spare ammo, and wait for cooldowns (defending outside SB’s ship, for example).
Q: The Mattock overlaps with the Viper, why can’t you simply use the same build with either a Widow or shotgun?
A: The fact that the Mattock overlaps with the Viper is precisely why it is a good choice. The chance to freeze per bullet is largely determined by damage, and both the Viper and the Mattock have very high damage and high rate of fire in case the previous shot didn’t proc (rarely but still happens). Shotguns are also the best at proc because of their multiple pellets. But as mentioned before, shotgun users are in and of itself a different breed and do not need Flashbang as much, they are designed for quick close range kills. The Widow user will never use it to freeze enemies, and the only weapons available for them to freeze are the pistol and the SMG, both of which cannot compare to the overall damage dealt and versatility in the Mattock and the Viper. Plus, the Widow user will more likely pick up AP /Warp Ammo or another power to use such as ED. The Vindicator is a viable alternative, but it’s fixed burst fire rate makes it less flexible to run-and-gun as you would with the Mattock, of which you will most likely be doing if you are rocking it the right way.
Q: What makes this build unique? Soldiers and Vanguards have Cryo Ammo as well, and anyone can get Flashbang.
A: I’ve tested them out, and to me, those classes don’t have the same synergy with Flashbang as the Infiltrator class does. Soldier’s ARush is pretty much the only power they’ll ever use, any other powers added to them is really window dressing, and they don’t have the CD passives to make Flashbang efficient. Both the Vanguard and Adept already have Pull and Shockwave for CC. Sentinels’ and Engineers’ primary powers are focused on stripping defenses, and you will rarely ever get to sacrifice a CD just to use Flashbang when you could to use other powers to strip defenses / kill. Plus, they don’t have Cryo Ammo. The Infiltrator’s unique quality is the sniper rifle time dilation that does not sacrifice a use of power to perform. This can be taken advantage of, especially if the gun you’re holding has lots of ammo in one clip. Adding Cryo Ammo to the Viper and the Mattock transforms them into the best ranged CC weapons available in the game. Flashbang has the largest radius of any CC powers, and can shatter frozen enemies. The + time duration, + cooldown passives from Agent make theses two powers even more effective. Synergy.
Q: You seem to say only nice things about your own build. Is there anything that it sucks at?
A: Yes. Jack’s recruitment covers a lot of ground, and the Agent Infiltrator will have trouble throwing Flashbang at long distances to make it land exactly at the right place. And freezing enemies from that long distance will cause them to fall behind cover often, making the overall mission longer to execute. Also, Grunt’s recruitment mission has a lot of heavies and the Viper cannot take them out as fast as the Widow can. These are the instances is when OSOK is preferred. Having played both types a number of times, I can say that those are cases where the Widow clearly does very well. The Widow Infiltrator is a pure Assassin, it is every effective and efficient, it is evolved around one weapon and the use of stealth. The Agent Infiltrator on the other hand, deals a lot of CC in a lot of ways to neutralize sections of the field with tactical superiority and perfect power CD management.
Other things that suck about this build:
- The Viper eats a lot of ammo and to fully restock is a pain sometimes. Dropped clips gives you only 4 rounds, stationary / respawnable ones give you 8. So you need at least 8 respawnable clips to fully restock, and the Widow in comparison only need 6. This is why switching weapons often is recommended to conserve ammo.
- In fights in which the enemies are spread out over a wide area in front of you, Flashbang loses its value as a CC power. In those battles, you become a typical Cloaking infiltrator. The OSOK Widow beats the Viper because it narrows the enemy line much quicker.
- As you know, frozen enemies do drop behind covers, which can be annoying. That said, there are pluses to frozen/knocked out targets: they can be used as roadblocks in tight passageways, and the enemies behind them will get stuck and become easy prey. They also can be used as meat shields, as demonstrated by the Cryoguard.
- As mentioned, be wary of enemies with homing projectiles, it’s easy to get greedy with the Viper, spending too much time exposed, and unaware of other attackers.
- You can't OSOK, therefore every word in this guide is heresy.
Well, that’s really it about the bad parts of this build. I’ll try to think of more.
IV. New Game vs. New Game +
When most people play the Infiltrator on insanity, they chose to play a new game instead of NG+ because they heard it’s much tougher. This means that up until the Collector Ship, all Infiltrator builds are pretty much the same: you got your sniper rifle, your smg and your pistol, you’ve prioritized your points into passives and Cloak. And up until that point, you’ve been a pure sniper using the Mantis, and you’ve relied on that setup and play style for a very big chunk of the game. But because the Viper is such a different beast, and because you get it so late in the game and so near the point of getting the Widow, most people ditch it and never fully looked into how to use the Viper in conjunction with the Infiltrator’s abilities. The same can be said with other classes and powers as well. Cryo Ammo, for instance, is an underrated power because it is the last priority to invest points in during character level progression. If you never played NG+, you never will know what it’s like to use Cryo Ammo Mordin’s recruitment, or use the Revy on Garrus’ recruitment. So the experience between a new game and NG+ is very different, where a new game is very much about role-playing, NG+ lets you concentrate on tactics and game mechanics, and finding out new ways to play. NG+ is also much easier on tech-oriented characters because they can get 3 upgrades before Horizon, and especially easier on the Infiltrator with 3 sniper rifle upgrades so early. It’s the biotic classes who gets the shaft on NG+, however.
V. Exploits and Bugs
- It’s known that Flashbang nullifies Harbinger’s powers, so Horizon and the Collector Ship missions are easier because of it. However, it doesn’t work all the time, and I would not rely on it too much. The build can take out multiple Collectors just fine without the glitch to begin with.
- Like all powers, both Cryo Ammo and Flashbang will eventually fail every once in a while due to other powers and / or effects interfering, such as biotics. Both powers seem to fail most often when the target is still in the middle of it's getting back up animation, so be aware of these instances.
- Another thing happens often is if an enemy has been knocked down multiple times, he/she will never be able to get up, and will never stop screaming. Sometimes they can get knocked in between doors and walls, so unless you can shoot them, the game won’t let you continue and you have reload.
- Bozorgmehr discovered that Flashbang can sometimes instantly kill protected husks, right now there's no way to determine how this gets triggered, but it happens very often.
VI. Squadmates
I think this is pretty much up to each player’s preferences, and the general strategy for them are not that different from other popular builds, but I’ll add in some of my experiences with them. The most useful squadmates are the best defense strippers in the game like Miranda, Garrus, and Samara. Mordin and Grunt are also incredibly useful because they set people on fire. I find Jack the best suited to go on SB’s ship because you can already strip shields with the lightning rods, and her constant Shockwave spam knocks them out into space. Generally, it’s better to conserve squad powers because you always need at least one available in case you’re exposed and you're waiting for CD or regen, so can you use that remaining power to disrupt them from attacking you. For instance, if Garrus has already used Overload on a group, you don’t need to use Grunt’s concussive if you have Cloak or Flashbang available. You save that for the time when both you and Garrus are waiting for CD and you need a distraction.
