Reasons for MW2 SAE Killstreak Not Working

The following can be the potential reasons why you are experiencing this default in your game:

  • Unstable Internet connection: If the system or the console on which the game is being played is not connected to stable and fast internet connectivity, this might be a reason for the SAE not working in the game.
  • Bug Attack: There may have been a bug that corrupted the game files as a result of an attack on them. That is why you are not able to use SAE in the game.
  • Outdated Version: The game files reported a few bugs that prevented the SAE file from being processed by Modern Warfare 2. The glitch caused was recognized by Infinity Ward, the developers of the game, and they released an update later which fixed the gameplay issues. If you are still facing the issue, there is a chance you are still using an older version.
  • Unfulfilled Requirements to use SAE in Modern Warfare 2: The game has certain fixed requirements like 7 kills in a row or at least a score of 875 points without getting killed, that enable the player to be able to use SAE Killstreak. Non-fulfilment of the same leads to cause this issue in your gameplay.
  • Restrictions from third-party software or apps in the peripheral: Even though the cause of an error cannot always be pinpointed, it has been found that some third-party apps may restrict a number of functions of some games.
  • Obsolete Operating System: An outdated operating system may also be the problem, as the old version of the software does not support the latest version of the game fully, thus making some features and manoeuvres ineffective and unusable.
