So far, the 3DS's AR (Augmented Reality) feature has been used very little to play games. So far, the only game that I know which uses it is the 3DS's built-in games called AR game (which required an AR card) as well Face Raiders (which only required the camera and some space to move around). Majesco Entertainment took an interest and decides to take things further with their upcoming AR game called The Hidden.
You are part of an elite squad called GEIST (Ghostly Entity Investigation and Strike Team) whose aim is to vanquish evil spirits that threaten mankind.
In the game, you will be able to scan, detect and kill ghosts using the 3DS camera. There will be boss battles, each would differ and would require some adjustments on your strategy. There are 6 different paranormal entities which you can battle with your high tech tools and weapons.
