Second one already covered. But I straying away from the dusty brown post apocalyptic setting. So scorched earth wouldnt quit cut it.
And I'm grateful for the advice, but Im not sure where you are getting at with the vengeful protagonist thing. The idea that rage fueling folks is exactly what Im trying to avoid.

Probably because you can't be angry at zombies; they didn't purposely become like that and then target your friends and family. Zombies aren't really an enemy, they're just a deadly object that's between you and what you need to survive. Aliens, in your case, are usually portrayed (when villainous) as intelligent creatures who exterminate, alla War of the Worlds. If you try to mimic this by giving the Aliens a very basic drive, then it will not become a very interesting story. I have two suggestions:
1.) Make the main protagonist bent on revenge, thusly getting many people killed by this obsession. It'll cause some drama between your band of survivors, which creates emotional moments.
2.) Make it post-apocalyptic. You know, a scorched earth sort of thing. This way, save the few survivors, the environment will be the obstacle instead of an enemy, which means you cannot fight back, but survive.
Well, that's all I got for now. Man, I really got to start writing this stuff down . . .
