Secret Modern Warfare 2 Mode. Global Thermonuclear War

This mode looks like a mix of Sabotage and Domination. There is only one bomb, but instead of carrying a bomb to the detonation point (sabotage). You go to the warhead and you try to gaurd it and surround it as you gain points for gaurding it. Then at the end the nuke goes off! BOOM! LoL, I wouldn't mind playing this. It seems like it wouldnt be that bad.
