Extreme Ghostbusters was released on April 2 2001 by Light and Shadow Productions for the Game Boy Color exclusively in Europe.
It was originally thought to be intended for multiple consoles. Playable characters are Eduardo Rivera, Roland Jackson, Garrett Miller, and Kylie Griffin. Every level begins with a mission debriefing by either Janine or Egon. In each level, the player must travel a location in the city and bust all the ghosts. There are more than 20 levels.
All Ghostbusters have a limited number of proton cannisters. The more cannisters they have, the longer they will be able to fire proton streams at the ghosts. They can continue firing proton streams by finding more cannisters.
Eduardo and Roland play the same: Both can climb, jump, and can hold up to 6 proton cannisters.
Garrett has 6 proton cannisters, but cannot climb or use stairs due to being in a wheelchair.
Kylie's disadvantage is that she can only use 1 proton cannister.
Throughout the game, the Extreme Ghostbusters can collect items to help them complete their missions. Most of the items(the proton cannisters being the sole exception) are stored in their inventory and disappear after being used. The items are not needed to complete the missions.
- Proton Cannister- Provides power for Proton Packs.
- P.K.E. Meter- When used, an arrow will appear above the selected Ghostbuster's head, pointing him or her to the nearest ghost.
- Ghost Trap- Even though some mission introductions instruct the player to trap the ghosts, it is never mandatory to trap them to complete the level. When the ghost trap is used, a second Ghostbuster(Kylie if she is not the one the player is currently controlling) will appear and drop the trap on the floor. The player and his or her partner must then use their proton streams to guide the ghost to the trap, then activate the trap to capture the ghost.
- Slimer- When used, Slimer will appear to protect the player from enemy ghosts.
