God of War developer Sony Santa Monica is working on an "unannounced new IP".
A job advert on Gamasutra for a senior level designer said "experience in designing or contributing to the development of an open world game is a plus". No other clues were given.
Is this the PlayStation Move game that Sony Santa Monica was reported to be working on earlier this month? That demo showed showed a floating hand touching and manipulating objects in a forest.
Since the release of God of War 3, Sony Santa Monica has been helping out God of War: Ghost of Sparta, God of War: Origins Collection and Starhawk.
