Honestly, the "Falling Skyscraper" DLC is tots a rip off of the falling skyscraper in BF4.
Infinity Ward: "dude you copied our fish ai for your bird background animations"
Dice: "dude at least we don't have loving crappy "dynamic" stuff going on. really, a telephone pole falling on a car is 'dynamic'?"
Infinity Ward: "oh" *Infinity Ward makes a DLC for a falling skyscraper*
Dice: "Dude what the forget, you pricks."
*Infinity Ward giggles*
