Spy Plane

The spy plane killstreak reward is unlocked at the beginning of the game so you do not need to use any COD points to unlock it.
If you have selected to use the spy plane killstreak reward then you will gain it when you have killed 3 enemies without dying.
When you have selected to use the spy plane killstreak reward it will appear in the sky and circle the map for 30 seconds. The spy plane killstreak reward will show up all enemies positions with a red dot on your map in the top left of the screen. You will see a line go across the map every 4 seconds which is when the spy plane is updating where the players positions are on the map you are playing.
If a player is using the Ghost perk then the spy plane will not be able to detect them so they will not show up on the map.
The spy plane killstreak reward is a simple one to use and an easy one to achieve as you only need to kill 3 enemies. The spy plane killstreak reward is useful on most maps but players are getting wise to using the ghost perk so not always effective.
The spy plane is most effective on the hardcore matches as you are not able to see the map in the hardcore matches so it really gives you and your team mates the advantage. The spy plane can be shot down quite easily by the enemy so be prepared for it to not last that long but most enemy players will save their ammo for more threatening aircraft that are likely to kill them like the helicopters.
