Nosgoth, the setting of the Legacy of Kain series, was mentioned in the patch logs of an AMD driver. According to a post at the Eidos Games’ forums, “Nosgoth” and “War of Nosgoth” were mentioned at the end of a list of games from this generation including Remember Me and Takedown: Red Sabre.
An entry titled Nosgoth also showed up on the Steam database which might be a hint at a new Legacy of Kain game. Earlier this year, gaming sleuth Superannuation found out that Square Enix registered the domain “warofnosgoth.com“
Not only that but the LinkedIn profile of composer Kevin Riepl mentions Nosgoth for Square Enix as well as indie game studio Psyonix.
The last title in the series, Legacy of Kain: Defiance, was released 10 years ago in 2003.
