The first image you have is a fake date etc. CONFIRMED by Sledgehammer Games themselves, here.
Also, the first teaser is fake because the logo for IW is the "Short cut logo." They always use the full "INFINITY WARD" logo.
Third is fake because it just says Modern Warfare. Look at any trailer, it'll always say
"So Wallcroft was Ghost and Burns was Roach?! If it is, I'm not surprised that Wallcroft's voice was similar to Ghost's. Don't remind me the Gaz, Wallcroft was near by Gaz in COD4 and he had a different voice. So that means that REAL Wallcroft and Burns K.I.A. and Mac covers Ghost and Roach in Bravo 6, like CIA mission Ghost a.k.a. Wallcroft."
No they are not similar, they are the same. Gaz Ghost and Wallcroft are all voiced by Craig Fairbrass.
Oh god, i pray for you every night since MW2, please remove death streak option forever!
it seems like the one who developed it has never been a player...
Please god, make ghost game be released without death streak option.
