Metal Gear Solid Delta: Snake Eater retains the suggestive and sexual content from Metal Gear Solid 3, including the Peep Demo Theatre, as confirmed by its Mature 17+ rating from the ESRB. This rating is attributed to the game's realistic gunfire, cries of pain, bloody combat, and the inclusion of "suggestive/sexual content."

The ESRB's detailed report highlights the game's intense combat and violence, with scenes depicting a restrained character being beaten and electrocuted, a character shot in the eye, and another set on fire and shot multiple times. Additionally, the ESRB notes: "The game contains some suggestive/sexual content: a man groping a woman's breasts; close-up camera angles of deep cleavage; a character briefly groping a man's crotch; a Peep Demo Theatre allowing players to view cutscenes of a female character's body from a first-person perspective."

The Peep Demo Theatre, an unlockable feature from the Subsistence and HD Collection versions of the original Metal Gear Solid 3, allows players to control the camera during a cutscene featuring Eva in her underwear. This feature is unlocked after completing the game four times.

Konami has officially announced that Metal Gear Solid Delta: Snake Eater will be released on August 28, and a new teaser trailer confirmed the return of the beloved Snake vs. Monkey minigame.

IGN's preview of Metal Gear Solid Delta: Snake Eater described it as "more like a very shiny HD remaster than the elegant remake it could have been." The preview praised the game's visuals and nostalgia but noted it might be too faithful to the original. The original Metal Gear Solid 3: Snake Eater received an impressive score of 9.6 from IGN.
