It appears that there is a power point in the map Mission in Modern Warfare 3 that has allowed a player to achieve a M.O.A.B in 1 minute and 43 seconds.
In Call Of Duty: Modern Warfare 3 you never want to be on an even playing field with enemies, this is due to the fast paced speed of Modern Warfare 3. In some maps you can find areas where you are at an advantage, these are areas where you can head glitch or have a line of sight that theÂ enemyÂ cant find or shoot, these are called power points.
There seems to be a a power point in the map Mission where you are able to have a great line of sight where a majority of the players spawn.
