The team behind the visual novel Steins;Gate, MAGES/5pb-affiliated developers, are reportedly working on a new first-person shooter that has been built almost entirely using AI "vibe coding" tools rather than traditional hand-written development. The news has drawn attention because Steins;Gate is a beloved, meticulously written game, making the announcement of an AI-generated shooter from the same studio a notable and, to many fans, jarring departure in both genre and development philosophy.

Details of the project itself are scarce, with early impressions characterising it as rough and unpolished, earning it the label of an FPS "slopfest" from commentators. The story reflects a broader ongoing debate in the games industry about the use of generative AI in development, with reactions largely sceptical of whether vibe-coded titles can match the quality associated with the studio's earlier, more carefully crafted work.
