The story with the secret church in Nier's philosophical action: Automata was followed by a new video published by the pioneer from the Reddit forum, and the game's developers commented on the finding.
Remember, the hidden area is behind the secret door of the town's Replica. No one but Sadfutago with Reddit found it, so the community had doubts about the credibility of the discovery.
The new sadfutago video shows the way to the church from the beginning to the end. It appears that the section is not finished — the black mass at the far end of the room is not available for interaction, and the sound dialogue is taken from another place in the game.
As for the developers, producer Yosuke Saito.
Nier: Automata released in March 2017 on PC and PS4, in June 2018 it appeared on Xbox One, and on October 6, 2022 it was believed that the last secret of the game was discovered in January 2021.
