2K Games already confirmed a year ago that Bioshock 4 will be done and that the project has been entrusted to the studio Cloud Chamber. We haven't had much more news on the project since then, as it is still in the early stages of development, however job advertisements published by the study may have revealed us an important novelty on the fourth chapter of Bioshock.
The location of Lead Systems Designer it describes the ideal candidate as someone who has the following characteristics:
“Our ideal candidate has an innate sense of how game systems connect and enhance one another in an emergent sandbox world, as well as for the player-facing signs and feedback that are required for an intuitive player experience. "
The words "sandbox world" could therefore indicate a decisive paradigm shift for the franchise, hoping however that the fourth Bioshock will be able to maintain the narrative depth reached by the three previous chapters, which have made the brand so much loved by audiences and critics.
