Under similar circumstances as Xenosaga II to III: A Missing Year, the rating that I give here does not really mean anything. This game is basically impossible to access today in any means and the only way I was able to access this in any form whatsoever is through translation by ValakTurtle of a playthrough by 桂樹 (shoutouts to these guys.... seriously they deserves kudos as without them, no person on this Earth would see this story).

Xenosaga Pied Piper is a Japan exclusive game for flipphones I think??? I can't really recall which phones or whatever had this game because this is such an obscure piece of media, in fact it is lost media in all but this playthrough with no way of emulating this game. It follows the story of Jan Sauer and his subordinates as they try to search for a prolific killer, Voyager who has been killing people utilising the UMN.

I am not going to spoil the writing here at all as that is the only real thing the game has going for it but it is so good. Like A Missing Year, this should have been made into an another game since it had no budget. If you want to watch Pied Piper yourself, here is the link below:

Definitely worth a watch, especially in the leadup to Xenosaga Episode 3.
