No, that's not a technical error. The newly announced DLC for NieR: Automata is called "3C3C1D119440927". And it takes the term "boss fight" to new heights, because it allows the player to fight CEOs of Square Enix and Platinum Games! You can see some of that fighting in the video below.
This DLC adds 3 new Coliseums. In two of these you'll literally get to fight against Square Enix's boss, Yosuke Matsuda and Platinum Games' boss, Kenichi Sato.
New costumes, based on the original NieR, are also offered in this DLC. To unlock these costumes and some other stuff (like cosmetics) you'll have to complete some sub-quests.
As of yet, there isn't an official release date for 3C3C1D119440927. But it's coming "soon".
