You're the Shadow Man, a person who can switch between the world of the dead and of the living. In Shadow Man , your mission is to prevent five serial killers from bringing about Armageddon. In the world of the living, you're mortal and have conventional weapons. When you die, you are transported to the world of the dead and you become Shadow Man once again. Which means you're not really mortal. In the world of the dead, you can't use normal weapons, your gun shoots ghosts which kill zombies and other creatures that live there. You also have different voodoo powers and weapons. And you're carrying a large inventory around.
The gameplay in Shadow Man is an action-packed mix of exploration, puzzle-solving, and combat. As the Shadow Man, you'll need to navigate through the world of the living and the dead, fighting off enemies and avoiding traps along the way. In the world of the dead, you'll use your voodoo powers and ghost-shooting abilities to take down hordes of zombies and other undead creatures.
