Proton Charging has a link to a video of the multiplayer setup and in-game action. The only downside is the audio is messed up.

The audio sounds like it has been fixed on the video on incgamers.com. Everyone can hear the whole interview now.

i think i believe i might have found out what crossing the streams does.
Watch at point 4.17 in this video
http://www.incgamers.com/Videos/490/IncGamers-Ghostbusters-Developer-Interview
At 4.21 is when it happens.

there trying to catch slimer then the rookie moves to the right and is onloading a proton beam and as he gets close to peter which is also firing there beams catch and a red ord come flying back towards the gun and blasts you back and makes you and peter fall.

ive watched this video like 40 times and i do not see anything hitting you other than that beam orb.

also once u fall down 2 things happen. right after the blast knockes you down, peter also goes down. also his proton beams shuts off immediately. after you get up u fire and then he fires a second or two after you.

This is also seen when all 5 of the guys are crossing the streams in this picture.




and soon after they all get blasted back also.

Now this is my take on it and if thats what crossing the streams does then wow! (*flame)

I liked the idea that if you crossed the streams, it would've erased all your 360/PS3 data, that would've made for both the lulz and pain at the same time, and yes, I know that they were joking when they said that.

Oh, and I feel dirty for saying it, since I'm sure Microsoft is going to use my money to make more crappy OS's, but, I guess come June, I'm going to upgrade to Gold.

I like that idea too. well idk we will see what pops up in the next month and a half on this.

Lol, actually, I was joking about that as that'd probably peeve alot of people off, but yeah, we'll have to wait and see. Personally, I think it should just end that particular session since crossing the streams = bad.

That would not be fun if you'd just defeated a difficult end of level boss and crossed the streams accidentally while defeating one of it's minions.

Well, I was referring to the Multiplayer. I think they mentioned that crossing the streams in single player won't do anything.
