And now, three months after, they arrived in their whole number: giant faceless humanoids were walking through cities of mankind, turning everything they want in ruins.

No need to tell who else came after these giants. And now whole Earth is in the slow outslaught of these horny creatures. As far as you remember, their manifest was short: "You humans are dumb and nasty, you'll be as our new toys now. Your lands in the good hands now." Anarchy is everywhere, and it's only a matter of time before some of these monsters will appear on your doorstep..." Describe where and how do you start your story.
