Global Thermonuclear War

Global Thermonuclear War is a hidden Multiplayer gametype in Modern Warfare 2. It may have been incomplete at launch or is going to be re-released as DLC. Each side fights to capture a Tactical Nuke in the middle of the map. Once a team has captured it, a countdown automatically starts. When the countdown ends, the Nuke explodes, killing all players on the map and winning the game for the team that captured the nuke. For a team to capture the nuke, players have to be in the area around the nuke. For every second in that area, a point is given to that player's team. Once 100 points have been scored by one team the countdown begins.

Trivia

 * The name of the gametype may be a reference to the movie War Games, in which a supercomputer plays a game of the same name on U.S. government computer networks, causing several U.S. leaders to believe that the events portrayed in the game are actually happening.
 * There is a Callsign Title called Global Thermonuclear War, which requires the player to call in two nukes.
 * One way to play it is in private match with a mod.
 * There is a bug, where if the player starts a private match with the mode Hardcore Headquarters, on a map with Rangers as a team (like Highrise). Start the match and select Rangers, the announcer will say "Hardcore Global Thermonuclear War".
 * Further investigation shows that capturing a nuke adds to the player's nuke count, making this mode a possible hazard for boosting.
 * The nuke detonates at the same location where a Tactical Nuke would go off on that map, rather than the objective exploding.
 * It has been mentioned that this may be in Modern Warfare 2's Map Pack 1.
 * Capturing the nuke takes 100 non-consecutive seconds. When in a private match, it is recomended the whole team cover or at the same time capture the nuke.
