Prompted by yesterday's huge leak, Infinity Ward and Activision have made Call of Duty: Modern Warfare 3 official.
"Wasn't planned, but you're clearly hyped, so here is the first of many Modern Warfare 3 videos coming in hot today!" wrote Infinity Ward community man Robert Bowling on Twitter.
Activision has so far released four Modern Warfare 3 teaser trailers, one for Germany, one for England, one for America and one for France; four countries players will get to fight in during the game.
The English teaser reveals a frantic attempt to barricade Westminster, London. The American trailer features a conversation that reveals a unit's journey from Manhattan to Brooklyn, New York as a submarine fires missiles into the city.
Modern Warfare 3 is a collaboration between Infinity Ward, Sledgehammer Games and Raven Software.
Multiplayer offers a "chunky" list of playable maps as well as two types of Spec Ops modes: Survival and Mission.
