"The following trailer exists entirely of actual gameplay", declares the E3 2007 trailer for Call of Duty 4: Modern Warfare. Just in case we were looking on and thinking it looks so utterly amazing that it can't possible be in-game, like.
Anyone who's been following CoD 4 will know that the plot revolves around the machinations of a Russian ultra-nationalist and the US and British attempt to nuke his plans into dust. Players will follow two intertwining storylines that culminate in a final showdown in Russia.
Oh, and it really does look ace.
