ZootFly created the unlicensed prototype early last year in an effort to license the property themselves. However, Randal claimed the video surfaced just as the studio and publisher Vivendi were wrapping up negotiations with rights holder Sony Pictures.

"They had no knowledge—we were already working on the game six to nine months at that time, and the license was either signed or about to be signed," Randal told Official Xbox Magazine. "What ZootFly did for us, inadvertently, is help sell the concept."

"When their footage came out, we were close to our green-light meeting, and when the executives saw the reaction from the fans, they immediately knew, 'Hey, Ghostbusters is going to be a big hit—we need to put this game into production," he added.

When asked about Terminal Reality's effort last year, ZootFly CEO Bostjan Troha told Shacknews: "I am sure the [Ghostbusters] game will kick ass...Unfortunately we don't have anything to do with this development."

Terminal Reality has since announced that the Ghostbusters game will appear on the PC, PlayStation 2, PlayStation 3, Xbox 360, Wii, and Nintendo DS this fall.

While PC, PS3, and Xbox 360 versions are being developed by Terminal Reality, Red Fly Studio is handling the PS2, Wii, and Nintendo DS versions.
