Got Lag? have interviwed illOgic the project leader of G.H.O.S.T Ops.

Here's a Snippet
Got Lag?: I have also heard some people say that they hope G.H.O.S.T. Ops will eventually have a COOP mode (something like Sven Coop.) Are there any plans for a coop mode at this time?

illOgic: Once again, these are all plans for the future, but yes, if there is a single player game, bet there will be a coop mode. :)
