What is berserk season 3?

As an AI language model, I don't have the most up-to-date information. However, it is worth mentioning that Berserk season 3 has not been officially announced. The anime series is based on a popular manga of the same name which has been ongoing since 1989. The first two seasons of the anime adapted different story arcs from the manga, but they did not receive a lot of critical acclaim due to their use of computer-generated imagery (CGI) and deviations from the source material.

As of now, there has not been any confirmation about a third season. The manga is still ongoing, and fans of the series are eagerly awaiting a continuation of the anime. However, due to the mixed reception of the first two seasons, it is unclear whether a third season will be made. In the meantime, fans of Berserk can continue to read the manga and enjoy other adaptations of the story, such as the recent video game Berserk and the Band of the Hawk.
