A diligenthas uncovered a handful of Silicon Knights' cancelled games. The investigation has unearthed Too Human 2 and 3, a horror title called The Box, and Eternal Darkness 2.
It appears Too Human 2 was to be subtitled 'Rise of the Giants'. Both this and the final chapter of the planned trilogy were cancelled before plans really took off.
Even so, a small amount of artwork is still available. Shadow of the Colossus, anyone?
Silicon Knights was also working on an open world horror game called The Box. THQ eventually took over with a switch of name. The Ritualyst was cancelled in 2009 due to a lack of funds.
Evidence has also been found for games called The Crucible: Evil Within, Siren in the Maelstrom, The Sandman, and King's Quest. All were revealed in the court case between Silicon and Epic Games.
Eternal Darkness 2 is also said to have been in production. Unfortunately, that title is now long gone.
