Raven Software has released today a brand-new video marking the developer’s 25th anniversary.

The video, which can be viewed below, features Raven Software’s two co-founders -- Brian and Steve Raffel -- reminiscing on some of the studio’s greatest accomplishments, memorable titles and what the developer has offered to past and present employees.

Additionally, current staff members at Raven Software left their own personal messages towards the end of the video.

Brian and Steve Raffel founded Raven Software in 1990 as an independent gaming studio, but publisher Activision acquired the developer in the late 1990s.

With a 25-year history in video game development spanning across multiple console generations, Raven Software has produced well-known titles like Call of Duty: Ghosts, Quake 4, Singularity and Heretic.
