3C3C1D119440927 is the first DLC pack for NieR:Automata. The content includes arena style gameplay with cosmetic item rewards as well as a small story detailing the events of a machine lifeform known as Plato 1728. In the "Become as Gods" (Xbox One) and "Year of the YoRHa" (PS4 and Steam) editions the content is already included without the need of extra purchases.
The rather strange title was explained by Square Enix as indicating "3 Costumes, 3 Coliseums, 1 Dream" followed by a date in plain numerals (27th September 11944) which the same as the date of the included music video and about six months before the events of the main game.

The DLC includes three arenas, the Underground Colosseum, Gambler's Colosseum and Trial of Sand, located at three previously inaccessible elevators in the base game. They can be accessed after receiving the quest: Mysterious Letter. Each locations has its own challenges and quest and some are only accessible with certain characters.
After completing the three arenas the player will receive the final quest: Mysterious Invitation which tasks you with going to the Amusement Park and investigating a newly opened elevator. Once inside, a TV is available to interact with and doing so will allow the player to relive the memories of Plato 1728. At the end of this small story, a music video by rock band Amazarashi is played as the ending credits to this piece of DLC content. After the video, the player can exit the Park and will now have access to special challenge tiers in each of the arenas. Finally, a unique boss fight with CEO of Square Enix Yosuke Matsuda as well as Platinum Games head Kenichi Sato can be accessed by persistently asking the Resistance Secretary inside the Gambler's Colosseum arena for a fight with you-know-who.
- It may not be a coincidence that the first part of the name, if read instead as hexadecimal code, indicates a type of ASCII group separator control code used to separate data tables in very old database systems stored on serial storage (1D) for a group of "<<" (a rewind symbol).
