Guys, after looking closely, I have to say I disagree. I think the shape of the head is different, the arms are a bit thicker than FO3s ghouls, and I think the only reason it kinda looks like that is because one of them in the magazine happens to have his mouth wide open similar to how the ghouls in Fallout 3 often were. It's similar, but not the same, even if they by some chance did in fact use the ghouls as a starting point.
Look at the undead guy on the far left. Look at the way exactly the same eye bulges out as on a ghoul. Look at the top of his head; the shape of his skull is the same, with the same contours. Look at how both of their brows stick out; it's clearly the same model.
Also guys, I'm not saying it's some awful sin to reuse assets, but considering they were already reused in New Vegas, and this is a completely different franchise, I would've thought they could come up with some new models after 2 years.
