The studio only recently released Doom: The Dark Ages. The game had the best launch in the series' history, although many initially doubted its prospects. Now, judging by the job posting, id Software is already preparing a new project.
ZeniMax has opened a position for a Lead Gameplay Features Programmer in its Dallas office. One can speculate about possible projects, but it is known that this division mainly helped other teams. The studio hasn't made a full-fledged major game in a long time. The job description makes it clear that this is an AAA project that will also be released on consoles. The candidate will work on new gameplay features.
There is a possibility that the studio is developing a new Quake. Although there are other options, such as Wolfenstein. There is no official confirmation yet, so we have to wait for news.
