Extreme Ghostbusters: Zap The Ghosts! was released in December 2001 by Light and Shadow Productions for the PC exclusively in Europe for £9.99. The game is a Bust-A-Move clone, which tasks you with firing ghosts from the bottom of the screen to the top of the screen. If you match up sets of three or more, the ghosts disappear. You need to eliminate all ghosts before they move to the bottom of the screen. The game includes Arcade, Contest, Challenge, and Edit modes.
