One of the characteristics of the two aliens was that they were "big" ... Considering that the Onion man wasn't considered "big" wouldn't it be obvious that two "big" things that look exactly like the aliens are the aliens?
Their targets are huge and the arena's drastically smaller than the alloted areas of the first two missions this time around. It's rather worrying that those huge guardian statues are just the bodyguards of their most intimidating foe yet.
I wonder when they'll have a mission that won't consist of at least one out of bounds-related death.
