Ghosthunter is set in a world where rogue ghosts have broken free from containment facilities, wreaking havoc across the globe. Rookie cop Lazarus Jones finds himself at the center of this supernatural chaos after inadvertently unleashing hundreds of ghosts.
The game follows Lazarus 's journey as he travels to different locations around the world to recapture the ghosts. He begins with a pistol, but soon discovers energy weapons that can drain away a ghost's energy. With these, he can capture ghosts using his "Ghost Grenade". However, Lazarus must also contend with solid enemies that require traditional shooting tactics.
The game features a mix of environments, from flooded bayous to sunken battleships and abandoned prison islands. Astral , a mute ghost companion, can aid Lazarus by reaching inaccessible areas and opening paths. Despite her usefulness, she must rely on Lazarus for protection, as she has no way to defend herself.
Ghosthunter was released in 2004 for the PlayStation 2 console.
