Dear Humans,
I am very sorry that I have to inform you about the upcoming invasion of our world by foreign forces. We, the management, want to sincerely apologize for allowing this oversight. Sadly, the degree as to which we can interfere in this conflict is severely limited as this would allow the opposing party to act in a similar manner. 
But please don't worry, contingencies have already been implemented to maximize the effect of the little support we can give. Thus we ask you, to work together in stemming the coming tide, so that humanity may remain on the victorious side. 
As long as humanity beliefs, there is hope.
Yours truly,
God of public relations
