Singularity developer Raven Software could be developing a next-generation first-person shooter, job ads for the studio have suggested.

The ads, which are listed on Raven's website, reveal that the studio is working on "an exciting next generation title". Another states that the studio is "at work on a first-person shooter".

Raven previously developed the surprisingly decent time-manipulation shooter Singularity, and has contributed to development on the Call of Duty series. However, it's perhaps most famous for its Soldier of Fortune series in the early 00s.

None of the job descriptions offer any hints as to which IP Raven's unannounced game could be related to.

Raven Software was acquired by Activision in 1997. Activision has yet to announce details on the studio's future projects.

Activision declined to comment when contacted by
