Infinity War have released a new trailer for their bonus map, 'Freefall'.  Freefall is a preorder incentive and available as a free download to anyone who preorders now. Check out the trailer above. As you can see Freefall pits you against the opposite team in a skyscraper that is falling apart.  As the match progresses the environment will change as pipes and debris shake free and paths through the map block up or new ones open up.  Info on the Call of Duty website says:

"With every drop, the accompanying shockwaves cause further destruction, disrupting sightlines and constantly evolving paths and chokepoints as the map changes in real-time."

Meanwhile, we have a trailer for the much discussed new Extinction mode. Aliens and exploding skyscrapers. What does it all mean?
