I recently tried out the Quarian Infiltrator in Mass Effect 3 multiplayer and turning the Geth against each other worked really, really well. But I observered that a few times my Sabotage power didn't seem to work on some enemies anymore.

What limits does the Sabotage power of the Quarian Infliltrator have? Why does it sometimes not work against synthetic enemies like the Geth?

  • It has diminishing returns on Geth Prime at least. Was it just them you were having trouble with? Mar 13, 2012 at 7:16
  • The Geth Prime were the ones where I noticed it, yes. Mar 13, 2012 at 8:38
  • Geth prime seem to get the effects except for the actual attacking allies bit, is this what you've observed? Or were they not effected at all, IE you didn't even see the red lightening effect on the Geth Prime?

  • @BenBrocka They are completely affected by sabotage, but not always. Mar 13, 2012 at 13:52
  • I'd guess Primes simply have a % chance to resist it. Seems to work 100% on normal Geth, and I THINK it always works on Pyro/Infiltrator geth, I'll try and test it later.

I played around in a solo-multiplayer session a bit and found the reason why Sabotage seems to fail sometimes. The duration of Sabotage decreases significantly each time you apply it on the same enemy. So the first time you sabotage a specific enemy you get the full duration, but if the enemy survives that and you sabotage him again, the duration will be much shorter than the first time. It seems to be roughly halved each time you reapply sabotage.

After 4 times sabotage seems to lose any effect on that specific enemy, and this is not specific to Geth Primes or other superior enemies, you can observe that with any Geth trooper. The reason it seems to happen especially often with Geth Primes is that most other enemies just don't survive long enough so that you have to use sabotage that often on them.


Sabotage is a very tricky power that requires practice to use. All Geth are subseptable to Sabotage as well as the Cerberus Turrets and Atlas. Against things like troopers or Maraders, it causes a weapons overload effect when they try to fire their weapons which damages them and causes a stun similar to hitting them with overload.

What makes Sabotage tricky is that it's a burst effect similar to overload and may affect a target NEXT to the Geth you were attempting to hack. You can negate this by targeting something in the open.

You CANNOT sabotage cloaked Geth Hunters. You ether need to drop their shields or hit them when they drop the cloak.

Sabotage takes a few seconds to actually rewrite the code of the object so they may freeze in place a bit or continue to attack you before it takes hold. THIS is the reason so many players may get frustrated. What you need to watch for is glowing orange lines washing over the target. If you see these lines you've successfully hit the target and in a few seconds it will turn on it's foes if there are any in proximity. If no one is close, it will simply stand there and not fire on you. When the lines wear off, it will reset back to it's "Kill Players" mindset and resume the attack. The clock doesn't start ticking for wearing off until the power takes hold.

Sadly (and this is the source of my frustration) the glowy lines seem to attract the attention of other players and unless it's a Geth Pyro, Prime, or Atlas, it doesn't live very long enough to serve as a distraction.

As addressed by the others, it does have diminishing returns when used consecutively on the same target. By the 4th pop, you may as well be hitting it with blanks as it will have no effect. Switching up targets is advisable as most of the enemies in close proximity to that unit will ignore you unless you're in melee range to deal with their rogue ally.

And yes, you will get credit for killing enemies with/under a Sabotage.
