Here's a quote I found on IGN from game developer Zootfly:
'Bostjan Troha, CEO of ZootFly, told IGN UK: "We are very glad to see the overwhelming response to the Ghostbusters prototype movies. What you've seen is indeed in-game footage of early prototypes on the Xbox 360, running on ZootFly's proprietary engine. Due to licensing issues, further development of the Ghostbusters game hit a bump on the road. But everybody here at ZootFly is working actively on resolving the challenges with the owners of the Ghostbusters IP.'
Holy hell I hope the get those licensing issues taken care of 'cuz this game looks like it would be crazy ass fun... crazy ass!
