"The Legacy of Kain series has fallen silent for some time. Earlier this month we broke news that Nosgoth is coming via Square-Enix, and it marks the return of the franchise after many years. However, one NeoGAF user has dug through the bowels of the internet and has unearthed evidence of ten failed attempts at new games in the series."

"The investigation comes from NeoGAF user Mama Robotnik, the same person who exposed many cancelled Silicon Knights projects last year."
