Please accept our apologies for not noticing this before, and how could we miss it! But Infinity Ward had confirmed that the multiplayer aspect of Call of Duty: Ghosts will be revealed mid August this year.
Sorry I haven't been on twitter much lately. We are in our death march push to finish game. Lots left to do. Looking forward to MP in august

This news could tie in with a pre-Gamescom event reveal; whether this will be another livestream or series of web videos is currently unknown.
When the reveal happens we’ll let you know in good time!
