Earth war, female war etc is to me a true classic and I hold it high up there in the alien comics and to me still is telling what xenos came from and much more.
I love the dark atmosphere in these comics, especielly female war where you see survivors struggling to survive on earth and at any moment you can get attacked by xenos if you arent careful, almost dead humans having their minds warped and try to get others to be killed by their chestburster, or humans who have been influenced by the closest queen, the queens able to affect some humans mentaly. And we get to see young queens making up their nests in the wild and try to start new colonies, in short its a nightmare. And showing the xenos able to survive a mega nuclear bomb and not being affected by the radiation, perfection, I love it.
