I've recently started GMing a Dark Heresy campaign and decided to use the included adventure "Dark Pursuits." My group managed to kill Skinner(with some help they enlisted from another gang) and I had to make up some bs excuse as to why they couldn't have his power sword(it was the first session). I was wondering what you guys thought was the best way to stop my players from using weapons of enemies that I throw at them? Should I stop them? I felt that if I didn't, then they would become too powerful too quickly. I know if it was a chaos cultist or something similar then I could simply say that it's tainted or something.
