Blinking into the blinding sunlight of the surface world you had only ever dreamed of, in the distance you see the outline of a giant humanoid figure making it's way towards you.
A new challenger appears!
It's a giant freakin' robot!
Loudspeakers blaring it yells the following:
Viral Wolf said:
"Humans....
There are two things you should know:
First, any human on the surface will be completely annihilated by our Human Eradication Army.
Second, oh. You're already killing each other. Never mind. Carry on."
And with that the giant robot trudges off through the bleak wasteland back to wherever it came from.
