Constantine is an action-adventure video game created as a movie tie-in license of the Warner Bros. film Constantine, in turn based on the Vertigo / DC Comics comic book series, Hellblazer. Players move John Constantine in an RPG-like style, collecting ammo, using an item to restore health and casting spells. Gameplay is a type of third-person shooter style, with changing camera views. Players can select from a variety of weapons to eliminate demons. Cutscenes initiate special missions or boss battles when they occur, giving a round of gameplay a different view. John can cast spells that can create lightning storms, expel demons, create swarms of flies or confuse enemies. Each requires the player to hit a sequence of keys within a small window of time, with John chanting at each keypress.
