Sega has already confirmed you'll see Shin Megami Tensei 3: Nocturne HD Remaster head west in spring of this year, but details since then have remained scarce. However, it looks like the game has already made it before the ESRB and received an M Rating.
As highlighted by a tweet from Gematsu, the ESRB has given Nocturne an M rating for blood, partial nudity, sexual themes, strong language, and violence. It's the same rating the game held before, so it comes as no surprise to SMT fans who are familiar with how dark some of Nocturne's themes go.
If you aren't familiar with Nocturne, it's not for the lighthearted. Some of the ESRB's descriptions highlights the acts of violence committed in Nocturne, like "a bloodied man snapping a character's neck" and "a character wearing the skinned faces of his victims." The game is also loaded with plenty of sexual themes and language, so, maybe not one to indulge in when the kiddies are around.
Atlus and Sega have confirmed that Nocturne HD will be out this year, but there's been little in the way of updates on that front since 2021 began. In the era of the Covid-19 pandemic, we've unfortunately seen plenty in the way of game delays and it already sounds like Nocturne struggled with performance glitches after launched in Japan. Atlus did however promise to investigate and fix any hiccups players were having with Nocturne.
