It's not human! It must be a creature from Mars!

It has a long, fat, leathery body, with two big eyes and a mouth, and tentacles around the face. But no arms or legs. It must rely on machines for everything. And behind it, some kind of machine is rising up - some kind of gun? I think it's going to aim at me!

Should I run for safety? Or should I stay here and face certain death? Or do something else?
