Hey guys. After the update that set 90 seconds on vent phases, it turns impossible to complete this feat on Hive Normal. We have only 3 waves of 8 adds each, so we have a total of 24 adds only. You need to fix this, I mean, for example, increasing the number of adds in each wave, turning possible do this feat on normal once, in description, says that we can do it on both, Normal and Elite version.
Unless something also changed on update 87, you can do it on normal....it's just hard. I got it done on a group the last week. Each vent phase (if you do not close the vents) has a 3rd group of 4 rock creatures that comes out, then disappears about 20 seconds later. 2 of the 4 disappear almost immediately with the other 2 following shortly after. You need to kill at least 2 of those before they disappear. Orbitals and supercharges will get the job done if you go at it co-ordinated. We actually took out 3 of the 4 on the first vent phase, so we took out 31 total technically. It took us about 3 tries, but it can be done. But to your point, it is harder than need be. That 3rd group of 4 each vent phase should be out for at least 30 seconds before disappearing. Good luck with it, Reinheld
