I’ve been stuck on this one as well. I was at like 33/100 forever. Then, after several runs, it hit 50/100. Then, several more runs, it was randomly 51/100. Yup, I’m running it on Malice+, but nothing really changes. I hate how there’s all this work I’d love to do with my Skullbreaker, but man, it’s super frustrating to do what’s required and still have nothing to show for it.
Metalfab smelter end event is a good place to do the achievment. There’s also a little corridor up some stairs near a medicae behind the big door you open in the manufactorum that usually has a horde or bunch of patrols that you can pull, bottleneck and then charge.
