Not quite. It has been roughly 10 years since I had worked on an old Doom conversion of Ghostbusters… and no matter how hard I try… I can't seem to get away from it. Recently a Doom community member created a Team based Deathmatch game called “Ghouls vs Humans” where players choose between several different classes and battle one another. Ghouls consist of a variety of types… but more importantly, You can also plays as several humans. Of note, the Ghostbuster. I decided to contribute to the project and donate a bunch of new artwork so it didn't continue to use the 10 year old images from the old Doom mod.

Ghostbuster Tips: Proton Pack recharges when you're standing still. If you kill a ghouls, pressing the Alternate fire button (you'll have to set one up in the controls) it changes your packs' fire type. You can switch to traps any time. Pressing altfire lays a trap (you can lay more than one). Pressing regular attack detonates all the laid traps.
