Kojima Productions and
Xbox Game Studios announced their partnership for the project at the
Xbox Games Showcase in June 2022.
Hideo Kojima stated that the studio was working with Xbox and its cloud gaming technology "to take on the challenge of creating a very unique, immersive, and totally new style of game—or rather, a new form of media". In November, approximately two and a half minutes of alleged gameplay footage leaked online. It depicted a character from a
third-person perspective, visually resembling
Margaret Qualley, walking through dark corridors with a flashlight. The scene concluded with a "
Game over" message, followed by the phrase "A Hideo Kojima game", and the title
Overdose.
OD was officially revealed by Kojima and
Jordan Peele with a teaser trailer featuring
Sophia Lillis,
Hunter Schafer, and
Udo Kier at the
Game Awards 2023. Kojima described the project as "
avant-garde" and "something totally different", and that players would "either love it or hate it". He further remarked that he believed its true evaluation would come "10 or 20 years from now". The game is being developed using
Unreal Engine 5. In September 2025, a second teaser trailer, subtitled "Knock", was released during Kojima Productions's 10th anniversary event. The teaser showed Lillis's character performing a candle lighting
ritual, until she gets immobilized in fear and ambushed by an unseen entity knocking and opening the door. Kojima stated the game would explore various fears, citing the sound of knocking as a personal example, while Peele would be addressing a "different kind of fear". Kojima suggested that
OD will be an
anthology horror game, with segments written by various directors he referred to as "The Avengers", including himself and Peele. Kojima said that unlike his earlier games,
Metal Gear and
Death Stranding, which he described as "system-wise similar to other games", with
OD the studio is attempting to "change the service model from the ground up". On November 23, 2025, Kier died at the age of 81. In a tribute statement, Kojima revealed that Kier did not complete his motion capture performance before his death, and that filming was planned to resume in 2026. == Reception ==
