A simple video of a clock ticking with the caption "Pov: Waiting for the update."

An image most likely featuring the CRETE, a scrapped entity that was mentioned a long time ago.

An image featuring a vent with a similar style to the end of Chapter 1 route ending 1 with the titan smiler encounter. The appearance out of the vent seems to resemble that of a modern day hospital waiting area.

A video featuring the player walking out of an elevator into a place that looks like the outside to the vent in the previous sneak peak.

A video featuring a teaser to the sublevels. A blank void with a desk full of computers piled on more computers.

Watch the cutscene.

A sneak peak of the album cover to the songs for the sublevels.

The official soundtrack for the elevator cutscene with the watcher.

Soundtracks posted for some levels in the sublevels or possibly sections of the sublevels.

A biohazard waste drum of sorts. For what, nobody knows.

A screenshot of a metro train's interior. Most likely for the sublevels, as for what will happen is unknown.

A sneak peak showing a possible revamped older level or an entirely new level. Its unknown as they appear to be changing a lot.

A soundtrack for the newly revamped Level 15 for Chapter 1 at the time.

Watch the video on your own, its peak.

A image featuring some FNAF 4 level nightmare creature.

A video of a blank image of what presumes to be The Hub, a backrooms level which has doorsways that lead to every level in the backrooms and is entirely safe with no danger at all.

Images proving my point that the video was the Hub backrooms level.
