Coinciding with the 25th anniversary celebration of the film's original theatrical release, the game reunites original cast members to recapture the unique blend of humour and fright that established Ghostbusters as a pop culture sensation.

Penned by original Ghostbusters writers Harold Ramis and Dan Aykroyd, Ghostbusters: The Video Game brings members of the original cast together for the first time in 20 years.

Players will have the chance to chase, attack, and catch ghosts in a funny and frightening battle to save New York from its latest supernatural plague.
Authentic Ghostbusters Experience: The game features the voices and in-game likenesses of Harold Ramis, Dan Aykroyd, Bill Murray and Ernie Hudson in an original story penned by the writers of the original films Dan Aykroyd and Harold Ramis.
