NieR: Automata's new 3C3C1D119440927 DLC dropped today (yes, that is what it is actually called), and it makes some great additions to the game. The bad news is that the process to get to play it is a bit convoluted.
The key is unlocking the Chapter Select feature, which doesn't happen until you have played through the game three time to get to Ending C or D. While many players have already done that, many of those same players kept playing to Ending E and made the ultimate sacrifice of letting the game obliterate any progress you have made and deleting all saves and game info - including having unlocked the Chapter Select feature, which is needed to play the DLC.
So if players achieved Ending E, they will need to play through three more times to again unlock Chapter Select to be able to play the DLC. Phew! Got that?
If you have access to Chapter Select, lets now talk about the DLC. It offers new sidequests and coliseum battles that give players costumes, cosmetic items and music. And you get some pretty odd boss battles, going against an animated version of Square Enix boss Yosuke Matsuda and Platinum Games' Kenichi Sato. The good news is the goodies for dispatching them are pretty nice.
So have fun with the DLC, if you can. If not, NieR: Automata is really good and you shouldn't mind a few extra playthroughs. Right?
