It looks like Nier Automata might still be harboring some secrets, as producer Yosuke Saito acknowledged a video showing off a hidden area.

Over a month ago, Reddit user sadfutago posted on the Nier subreddit asking the community how to open the door for a church in Nier Automata, as they could access it but a friend couldn't. This particular area was in the Copied City section of the game, specifically. The post was joined by a pair of images showing off the church. The only problem is that prior to this post, this church had never been discovered, and subsequently the community has exploded over this mystery.

Then, on July 25, sadfutago shared a video showing them entering the door that eventually brings them to the church. Entering the door brings them to a long ladder, at the bottom of which is a doorway that leads into a long, spiraling corridor. Eventually reaching the church loads is an unused cutscene, with voiceover used from another portion of the game.
