Was watching this IGN video on brutalities - at the 0:24 second mark, just as Kitana pierces Scorpion's head from behind and rips it off, a "dark figure" resembling a ninja peaks out from behind the damaged truck in the background, then scurries back! It's the arena with the crashed air plane.
It kinda reminded me of how the characters used to peak out from behind the tree in the Living Forest of MK2.
Has anyone seen this yet? Anyway here's the link to the video:

Sorry if this has been posted before, guys.
