Bandai Namco Studios Singapore is the lead studio developing Metroid Prime 4 in collaboration with Nintendo, according to a Eurogamer report citing multiple sources.
The studio employs former LucasArts Singapore staff who previously worked on the cancelled Star Wars 1313, among other things.
Metroid Prime 4 was announced for Switch at E3 2017. The announcement contained nothing more than a logo, and Nintendo did not announce which studio was developing the project.
According to Eurogamer, there is no indication that Metroid Prime 4 will launch this year, as the game is still early in development.
Eurogamer said it has yet to verify another rumor that popped up alongside Metroid Prime 4 earlier this week, which is that Bandai Namco Studios Singapore is also developing Ridge Racer 8 exclusively for Switch.
