Well, I'd say their may be a few alien deaths due to heavy machine gun fire, or maybe a lucky close range shot from a shotgun (even though that will result in an acid bath
) but I personally don't think their will be too much alien vs human conflict. I think they said that a time or two the military arrives just to find that the creatures have already gone. I personally don't wanna see too many aliens wasted by modern weapons. Just high tech predator weapons
