The Japanese Twitter for NieR: Reincarnation announced that the game will get a FFXIV collaboration event. It will start in early Summer 2022, and more details will appear in the near future. This collaboration event appears to be exclusive to the Japanese server for now.
This is not the first time that the worlds of NieR and FFXIV collided. A crossover event between NieR: Automata and Final Fantasy XIV resulted in multiple raid quests and glamor items for players’ Warriors of Light. Previous NieR: Reincarnation collaboration events (such as the Drakengard 3 one) resulted in limited characters and weapons. It is likely that the Final Fantasy XIV event will be the same.
The Final Fantasy XIV collaboration event is part of the NieR: Reincarnation first anniversary celebrations, according to the hashtag on the announcement tweet. During the anniversary stream held on February 13, 2022, Square Enix announced that it would also release merchandise in commemoration of the game’s first year. The game first came out in Japan on February 18, 2021. Square Enix released the global version several months later on July 28, 2021. As of September 2021, the game has been downloaded over 15 million times worldwide.
NieR: Reincarnation is readily available worldwide on mobile devices. The FFXIV crossover event will go live in NieR: Reincarnation some time in early summer 2022.
