We really, really, really wish we'd gotten a hold of IGN's question list for their latest interview with Terminal Reality's Brendan Goss before it went live. A two-page article chock full of interesting new Ghostbusters: The Video Game details, the interview unfortunately almost fails at getting new co-op info.
Almost.
Brendan Goss offered this cover-all description of the online co-op in Ghostbusters:
IGN: Can you tell us anything about multiplayer?
Brendan Goss: Ghostbusters does feature a number of online co-op multiplay modes. These are set up as calls around the city that the Ghostbusters go out on.
We can speculate all day here -- and please do -- but I'm about six times more interested now, and I was pretty pumped to begin with. I wonder if any of these "calls" will lead you to an area where waves of enemies attack...like a "Horde Mode"...?
