It seems Metroid Dread is off to a strong start according to the latest information from NPD regarding the launch in the United States. The report notes that the game had the highest launch month sales of any Metroid franchise release in tracked history, with launch month dollar sales being nearly double those of Metroid Prime, which was the previous series best. It is also worth noting that this only applies to physical data and not digital sales, which means the game likely did even better than expected.
Overall, Metroid Dread was the third best-selling game in the US last month across all platforms. You can see our review of the game here.
