You need to do it at same time.
Each player has to have the sample in hands and you have to insert them at same time (synchronize with countdown given by voice).
Don’t expect you have 5 seconds. You have 1-2 seconds.
Someone here on forum helped me to complete it and that’s how I have learnt it.
We failed it 2 times, and the 2 times the samples were inserted in the window of the 5 seconds.
To complete it, launch it at the lowest difficulty. If you have big difficulties to complete it, I advice 3 zealots with Thy Wrath Be Swift to avoid any stunning effect when you will want to insert the samples (if you’re hit you loose 1 -2seconds, enough to make it fails).
Precision I dont’ expect Thy Wrath Be Swift to avoid you to loose the container if you get hit… however you could take again the samples and insert them in the time window if you are not stunned. But the best is to wait that enemies are not around you… however, easy to say, it rarely happens for the 3 players at the same moment…
ah, i see. tried it some time ago (on sedition or so), put the batteries down in front of the tubes, inserted them within 3-4 seconds, but with that bugged timer sure it didn’t work as we were only 2 people.
The timer may be bugged but it’s doable. Did it today, 3 people with voice comms and we did a countdown and put them in at the same time. I have tried it with 2 and didn’t work. Just get 3 ppl if you want to do this.
