Kain II, also known as Kain 2, was a cancelled Legacy of Kain game, the planned second title in the series and the earliest concept for a sequel to Blood Omen: Legacy of Kain. The project was commissioned by Activision and included competing proposals by both Crystal Dynamics and Silicon Knights, with the deteriorating relationship between developers presumably ending production. The project was never officially announced and no associated parties have commented on the title, possibly for legal reasons.
