Shadow Complex 2 may have been shelved, but that doesn't mean it will never come out.
In a recent interview with Gamasutra, Epic Games design director, Cliff Bleszinski said that the game is pretty much designed.
"Shadow Complex 2 is sitting there, it's actually largely designed, we just need to find a partner that will help us to finish it so we can bring it to market."
Shadow Complex 2 was shelved so Chair could work on the iPhone hit, Infinity Blade.
"We needed a flagship product for iOS, plain and simple," Bleszinski said. "And we could have ported Shadow Complex, but it would have been a lot of work and it might not have been the right fit. And then Donald Mustard suggested Punch Out!! with swords with RPG layers and we were like, 'Yes!'"
