Metroid Prime 4
A new First Person Adventure entry in the series focused on isolation and exploration developed by Retro Studios (after a development reboot), set to be released on Nintendo Switch.
Announced at E3 2017, Metroid Prime 4 was set to return to the roots of the first Metroid Prime game with a focus on First Person Adventure gameplay and a big emphasis on isolation and exploration.
On January 25, 2019 Nintendo announced that the development of Metroid Prime 4 had been restarted with original series developer Retro Studios taking on development duties. The original version in development by the "new team" (rumored to have been Bandai Namco Singapore/Japan) has been canceled due to not meeting NIntendo's internal standards for the series.
