Noox is a 3D first person medieval fantasy ghost investigation game that can be played solo or co-op.
Use magically powered tools to collect evidence left behind by ghost hauntings, sort through the clues to decide which type of ghost is haunting the location, and assemble the necessary runes on your trap to capture the ghost and stop the haunting.
But beware of draining your mana too fast by using too many tools at once, because the ghost will sense your weakness and use that moment to attack!
