Hmmm, I know for a fact how most zombie apocalypses would pan out, and how to survive in them. Though what kind of Alien Invasion are we talking about here? Independance day, Alien, Predator, AvP, those 80s alien movies, half life 3, what kind?! So, being eaten alive at some point, or being probed at some point....decisions decisions....
I hope it's not WWZ zombies...
