April of this year marks NieR?s 10th anniversary. To celebrate, Square Enix will host three different livestreams on March 29th, all lasting for a combined total of roughly 10 hours. Two of the three streams will require viewers to pay. On March 29th, Square Enix plans to go live with the first stream at 11:59pm JST (or 7:59am PST).
NieR?s Japanese Twitter account outlined the 10th Anniversary?s streaming details in a tweet. Gematsu translated the information as follows:
