Platinum Games, the developer of acclaimed action titles including Bayonetta and Nier: Automata, contributed to the development of Konami’s Metal Gear Solid Delta: Snake Eater, Konami has confirmed. Specifically, Platinum created a new version of Snake’s Nightmare, an Easter egg that longtime fans of MGS3 will no doubt relish the return of.

Snake’s Nightmare is a third-person action sequence that is accessed by saving the game when Snake is captured and thrown in prison. When the save file is reloaded, instead of going back to the prison, players wake up in a hellish otherworld where a mysterious man wielding hook-swords takes on demons in a graveyard.

The minigame, also known to fans as Guy Savage, was originally written and directed by Shuyo Murata, who contributed to a number of other Metal Gear Solid projects as part of the original Kojima Productions team. Although Metal Gear Solid 3 has been re-released in various forms since its debut on the PlayStation 2, Snake’s Nightmare/Guy Savage has been omitted in the majority of them.

For Delta, a complete and faithful remake of the original MGS3, Konami went the extra mile and brought in Platinum to rebuild the hidden mode. As stated in our review, it’s an excellent return for the easter egg. Platinum are masters of the action game genre and previously collaborated with Konami on Metal Gear Rising: Reveagance, a spin-off focused on Raiden. Their expertise is very much on show in Snake’s Nightmare, which feels sharp and satisfying to play.

In GameSpot’s Metal Gear Solid Delta: Snake Eater review, we gave the game a 9/10, saying it is “a safe but successful modernization of a beloved classic” and a “gorgeous game that brings MGS3 to life in stunning new detail.”
