Killstreaks are things that help you throughout and reward you for getting so many kills and not dying. The more kills required for a killstreak, the more helpful it is. The lowest killstreak reward is the UAV recon and the highest is the Tactical Nuke. There are a total of 15 killstreak rewards. This list contains the last four; Chopper Gunner, AC-130, EMP, and Tactical Nuke.

11 - Chopper Gunner

The Chopper Gunner Killstreak
The Chopper Gunner is one of two popular killstreaks to get a Tactical Nuke. The Chopper Gunner becomes available at eleven kills in a row. When the Chopper Gunner is acheived and used, the user's screen turns into a "thermal" scope on the chopper and enemy players show up as a red square. Cold-Blooded users will not have the red box. Chopper Gunner can get a lot of kills fast once you find the enemy spawn point. However, the chopper is low to the ground and only contains one flare to divert missiles. Once it is gone, the chopper can be shot down easily. It lasts for fourty seconds.

11 - AC130

The AC-130 Killstreak
The AC130 is the other of two popular killstreaks to get a Tactical Nuke. The AC130 becomes available at eleven kills in a row. When the AC130 is acheived and used, the user's screen turns into a "thermal" scope on the plane and enemy players show up as a red square. Cold-Blooded users will not have the red box. The AC130 has three different guns, the 105mm, 40mm, and the 25mm. The AC130 is high up in the sky and contains an infinite amount of flares. This makes it extremely difficult to shoot down and almost always requires two players to try to take it down. It is best used on open maps like Wasteland or Afghan. It lasts fourty seconds.

15 - EMP

The EMP Killstreak
The EMP killstreak is probably one of the less used killstreaks at fifteen. An EMP (ElectroMagnetic Pulse) disables all enemn electronics. Because it does not actually kills anyone, players usually skip over it. Other than disabling everything on enemy player's screens, it also destroys any enemy aircraft in the sky. They will also not be able to activate any of their killstreaks, while they can still earn them. It will also make all player's screens fuzzy when the EMP is first activated. You team's screen will return to normal but the enemy's will stay fuzzy. It is impossible to destroy an EMP.

25 - Tactical Nuke

The Tactical Nuke Killstreak
The Tactical Nuke is the most coveted killstreak and also the hardest one at twenty-five kills. A Tactical Nuke ends the game instantly and kills everyone on the map. Once activated, a ten second timer will appear on all screens, counting down to the nuclear warhead goes off and the score will freeze. Once detonated, the white light will brighten the map, the timer will slow, cars and killstreaks blow up, and all players will die on the spot.
