On the second floor of Graniny Gorki, there is a library/desk room on the west side of the wall that features three notable paintings and a magazine. The paintings are Spoiler:"Salvation." and "Promise." which depict God, and "St. Alessa Gillespie: Mother of God, Daughter of God.", and are taken from the Church from Silent Hill 3. There is a fourth painting in the room depicting the head of a woman, but it's not known where it originates from. The magazine can be found on the desk towards the back of the room, and is a copy of the May 2004 issue of Electronic Gaming Monthly promoting the game on the cover.

EVA's English voice actress in Metal Gear Solid 3: Snake Eater and Metal Gear Solid: Peace Walker was credited under the name Suzetta Miñet. Fans widely assumed that this was a pseudonym as she had no other credits in anything, which sparked years of speculation as to who she could be. One of the most leading theories was that EVA was voiced by Debi Mae West, the voice of Meryl in Metal Gear Solid and Metal Gear Solid 4: Guns of the Patriots. However, while West acknowledged that the characters sounded similar, she denied she was the voice of EVA in 2015. Konami would eventually confirm in a 2024 behind-the-scenes video promoting Metal Gear Solid Delta: Snake Eater that the pseudonym belonged to Jodi Benson, who was best known for voicing Ariel in Disney's 1989 adaptation of "The Little Mermaid". Benson explained that she used the pseudonym at the recommendation of the game's English voice director Kris Zimmerman Salter, because of her association with Disney and other family-friendly roles aimed towards younger audiences at the time. The name itself was based on a pet dog Benson owned in her childhood named "Suzette Monet".
