Following a leak of information over the weekend, Infinity Ward has announced Call of Duty: Modern Warfare 3 and released four teaser trailers.

Infinity Ward's Robert Bowling tweeted, "Wasn't planned, but you're clearly hyped, so here is the first of many Modern Warfare 3 videos coming in hot today!"

The four teaser trailers each feature a different country: Germany, England, France and America. The geographic scope suggests recent rumours that the game follows a "World War III" premise may be true.

Modern Warfare 3 is being developed by three studios: Infinity Ward, Sledgehammer Games and Raven Software. It is scheduled for release in November.
