Modern Warfare 3's multiplayer modes have seemingly been detailed as part of a massive leak.
The Infinity Ward, Sledgehammer and Raven-developed game will launch on November 8, 2011, according to Kotaku.
Competitive multiplayer will reportedly feature 20 maps - although they may not all be available at launch (DLC, cough) - while there will be two types of Spec Ops game modes: Survival and Mission.
According to the report, Spec Ops games will feature a mixture of mission-based levels like those found in Modern Warfare 2 and survival maps which pit players against increasingly difficult waves of enemies (sounds like Treyarch's Zombies).
Reported multiplayer maps:
Alpha, Alps, Bootleg, Bravo, Brooklyn, Carbon, Coast, Dome, Exchange, Hardhat, Interchange, Lambeth, Meteora, Mogadishu, Paris, Plaza 2, Radar, Seatown, Underground, Village
Spec Ops modes:
Carbon, Dome, Radar, Seatown, Village
Civilian Rescue, Flood the Market, Invisible Threat, Little Bro's, Out of Africa, No Fly Zone, Wing Man
As well as the multiplayer and Spec Ops details, a whole host of single player campaign info has been revealed.
