Through leaked advertisements, the next Call of Duty game should be Call of Duty: Ghosts
. Now, Activision has a teaser site up
that further affirms that this is most likely the title.
The website features a mask of Ghost, the British soldier who died in Modern Warfare 2. The site lets you hover over the mask where there are links to various Twitter or Facebook accounts mentioning the game.
Now, Ghosts could be a prequel to Modern Warfare 2, but I wouldn't be surprised if it's about someone else taking up the mantle of Ghost in events after Modern Warfare 2. Highly unlikely, but I wouldn't put it past them to do so. The game's being made by Infinity Ward and is due out this Fall with word is the game will be unveiled May 1st.
