It's fake, even though I like it haha. I've seen the film and it's not in it. The preview video they posted however is legit, no idea why/how they were allowed to publish a preview of the films OST, it may get taken down later we'll see.
Well, that’s my remake of the prologue cue lol. It’s in the film and it’s mostly the same track but slightly altered at some places and has a different ending. I love what Ludwig added to the cue when
the Protagonist collects the bomb. It added to the atmosphere and made the scene much more intense. But I really prefer the prologue version for what comes after - them escaping.
The second part of the video (the sizzle reel). The intro was used in a cue when
The Protagonist comes out of the turnstile and runs and Neil runs behind him and removes his mask/helmet.
