First we were shown a little sample of what the Infernal Engine is capable of. The setting was the New York Public Library reading room which should be familiar to any Ghostbusters fan. The fully rendered backgrounds were gorgeous and we watched as a thousand boxes were moved about the room simultaneously, objects were sliced using the Proton Pack and slime tethers were used to link objects together and hang them from the ceiling.

I will say that the crowd technology in Ghostbusters is the best I have ever seen. With a camera perched high above an intersection, we were able to see fifteen hundred people at once, all moving with their own individual AI, moving aside if they bumped into each other and never passing through or getting stuck all jittery in a corner. We came down to ground level and were shown some crowd reactions which were also impressive.

Anyone who has seen the films will be familiar with the ghost catching mechanic employed in the game. The PK emitter is used to detect the ghosts and once you've detected them your handy dandy Proton Pack comes into play with its various powers such as Dark Energy, Freeze Beam, Shot Blast, Neutron Generator and the Slime Tether. Once the ghosts have had some of the fight taken out of them you can begin the process of grabbing them with your beam and capturing them in the ghost traps.
Here was where the PS3s Sixxaxis controller came into play. Utilizing a mechanic similar to that of Folklore, you use the controller to capture to grab the ghosts and then by shaking the remote, slamming the ethereal enemies into the ground until they can finally be trapped. Some enemies require multiple Ghostbusters to bring them down and often your AI buddies will not only help you by throwing down the ghost traps for you but can also help by adding their steam to yours (don't cross them!).

Your fellow AI Ghostbusters aren't the only ones who can help you. You real life friends can join you as well with online co-op play and specific co-op missions and mini-games. Some competitive play missions will also be available for you ornery types. Each mission will of course yield you a fee which will allow you to then make improvements to your beam pack.

All the original cast members would be providing their voices for the game including Bill Murray, Dan Aykroyd, Annie Potts, Harold Ramis and the rest of the gang.
