'Daemon in the Shell' not triggering...

[BlackDragon]

Anyone else have this problem? I've done as the achievement says twice now - incapacitating three enemies with a single Detonate Grenade quickhack. But nothing's popping. Does it HAVE to be the Legendary version of the Quickhack? 'cuz I've been using an Epic version, seeing as there's nothing to indicate that shouldn't work.

Is it bugged, or am I doing something wrong?

So What I learned was even though I had the legendary quickhack for "Detonate Grenade" it wasn't working. In order for this to unlock you lust have the purple one. I crafted the purple "detonate grenade" and it unlocked first time I tried. So we know the crafted purple quickhack for "detonate grenade" definitely works. Hope that helps.

Interesting... I did it with a purple one I found somewhere. For me, it seemed like the trick simply was 'more enemies'. There's a side-job involving the crazy 'prophet' you find near Viktor Vektor's ripperdoc shop, that ends with you crashing a weird meeting between a dozen or so Maelstom gangoons and a handful of Arasaka-looking Corporats. They wind up clustered pretty close together. I hit one of the Maelstom-types near the middle of the group with Detonate Grenade, and took the entire lot of them, save for a single Corporat, with that explosion alone. Boom, cheevo dropped.

Best guess? The enemy you use the hack on doesn't count as one of the three, meaning you need a group of at least FOUR foes close together in order to get it.

yeah i had this exact problemtoday. the detonated grenade killed the dude holding it and 2 others but achievement wasnt triggering (legendary version). so yeah either the one holding the grenade doesnt count or it really only works with the purple one. i will have to keep trying then. third possibility is i tried it with my old hacking centered character whichs save goes back all the way to patch 1.1 or so. so that could also be a problem but somehow i doubt it.

I did it with the Legendary. It doesn't have to be the purple.

I also failed it quite a few times before I got it to proc following a guide in the guides section. Main problem is that a lot of enemies either aren't close enough to their allies, or aren't using the right sort of grenade (too many EMPs). They pretty much need to have a frag grenade.
But yeah, there is a group of 3 gangers on a couch just off the east side of the main road going down through Pacifica. Can quickhack the middle one from the road above without them seeing and trigger the grenade. That did it for me.
