The trailer didn't have much information other than some of the cast members doing motion captures. The cast includes Sophia Lillis, Hunter Schafer, and Udo Kier. And of course, there is more. Jordan Pelee also walked out onto the stage after Kojima and said he was collaborating with Kojima for the game.
Other than this, there is no information about the release window or any other information about OD.
