Between the new graphics, art style, and the quicker, crazed pack attacks, they totally make me feel like that scene when Will Smith entered the dark building to save his dog.
Except I dont go rush after dogmeat into dark buildings.
They're more like legit zombies now. But I think that's purely due to animation and texture quality.
The lying in wait behavior freaked me out the first time I encountered it! I was clicking the lurker thinking it was one I'd just killed, hoping to loot the corpus, and all of a sudden it's standing up!
The only reason I knew better than to let a suspicious corpse go unchecked is thanks to how you shouldn't trust anything at first glance in the Wasteland. VATS can target them before they get up, thank Todd.
