Overview
- The series’ Japanese account posted a 21‑second teaser titled NieR: Cosmic Horror as April 1 began in Japan, showing a biomechanical figure with a tentacled head and the Emil mask in the background.
- The post labeled the item a “new project” without saying if it was a game, which led outlets to flag it in April Fools’ roundups and treat its authenticity as uncertain.
- The official NieR account later said the Cosmic Horror post was an April Fools’ project, according to PC Gamer, ending short‑lived speculation that it was a real announcement.
- The teaser followed Square Enix’s February video that closed with “NieR: Automata to be continued,” a message outlets took as a sign that more NieR work could be in development.
- With no new mainline entry since 2017’s NieR: Automata, the prank stung for fans who have waited years and now must watch for a formal reveal from official channels.
