Yes, they are but the 'dark' versions are meant more to show the 'truth' of what Advent actually is, they're not the actual propaganda for Advent, that's more Xcom.

@Trash Mammal The faces appearing human is the whole point, they are prorpaganda posters

I feel the faces in the 'dark' versions should be less... human. After all, humans were turned into those hybrids you mainly fight, right? It'd only make sense.

lol the realistic faces

This gives me cursed images vibes.

And where is the viper wife? Where's this guy's wife, Viper? Good question, isn't it?
