This discovery comes from an online portfolio of a UI designer (name witheld to protect their privacy) who worked at Bend Studio from 2022 until March of this year. In their resume, we can see that he worked on an unannounced Bend Studio project, but the interesting part lies within images of their work, where we can find designs for projects he worked on, including concepts related to a project from Bend.
The concepts show design explorations for what appears to be a third-person shooter. One of these designs uses an image from Days Gone as a placeholder, which we know is a placeholder due to the contrast made by the UI elements with this game. Thus, it is safe to say that this project is not related to this franchise.
Despite not knowing the exact date of this material, we know that the only video in the list comes from a Google Drive file uploaded in 2023. This suggests that the other images might also be from the same year or possibly from 2022.
