This is a Fanmade Trailer of Black Ops 4 - Using the Theatre mode. There are no actors, no scripted scene's. Only real Black Ops 4 gameplay.
Because there were no scripted scene's, and no actors. It was a real challenge to create something that made sense the whole way through. And I feel like it is lacking in that sense. I would call this trailer an "Overall cinematic trailer which covers a few new features of a new imaginary in-game update. But is filled with shots to show variation of action".
I have wanted to use Black Ops 4's camera path's and theatre mode for a long time to create an almost industry standard game trailer. However there are definitely some technical issues with the theatre mode. For example some parts of the HUD were not able to be disabled, etc...

The fan trailer also got a shoutout and recommendation by the Lead Game Designer of all the Call of Duty Black Ops games since World at War.
