"Get ready for Skyjacked, one of four new maps included in the Awakening DLC Pack. Skyjacked brings the Call of Duty®: Black Ops II fan-favorite Hijacked back to life on a security VTOL over urban Zurich, offering a variety of new ways to explore the map with Call of Duty®: Black Ops III's core movement system."
— Official Description
"Fan favorite "Hijacked", re-imagined as a Z.O.F. police VTOL, hovering over rioting downtown Zürich."
Skyjacked is a remake of the fan-favorite map Hijacked from Call of Duty: Black Ops II. The map is set onboard a futuristic police airship overlooking Zürich. It is almost identical to its predecessor and features new wall running spots and a new entrance to the bottom level of the map.
A dynamic theme exclusive to Season Pass holders for PlayStation 4 was released in April 2016 that is based on Skyjacked.
The skyscrapers seen below the map are actually an illusion. they appear very far from the VTOL but if the player falls to their death they can see that they will actually only fall for a very short amount of time and land very close to the VTOL.
If one looks at the floor of what used to be the hot tub, they can see a UAV underneath.
