Nihilistic the developer behind the canceled Starcraft: Ghost and a bunch of PlayStation Vita shooters were also working on a God of War space for PlayStation Home. Two resumes note the unreleased God of War PlayStation Home space, which had mini-games. Sony Computer Entertainment America later hired Nihilistic to created a Ratchet & Clank home space and later Nihilistic developed PlayStation Move: Heroes.
What else was Nihilistic working on? A LinkedIn profile reveals Nihilistic had a third person underwater shooter for PS3 and Xbox 360 called Deep Rift, a top down PS3/360 shooter called Alien Hunters, and an unreleased video game for the Chronicles of Narnia: The Voyage of the Dawn Treader. This demo reel from the VFX artist on those titles has a bit of Starcraft: Ghost at the end.
