Swarm

"Call in a swarm of lethal Hunter Killer drones."

- Scorestreak description.

Swarm is a Scorestreak in Call of Duty: Black Ops II, they were first seen at the end of the multiplayer reveal trailer.

Call of Duty: Black Ops II
It calls in a swarm of Hunter Killer Drones to circle the map to attack enemy players. Further, the drones continue to kill spawning players as long as there are drones still present. The drones are visible in the sky throughout the map during the duration of the killstreak, appearing as orange lights circling the map. They function entirely like normal Hunter Killer drones, attacking any players and air support they see. Many players see these abilities as comparable, or better than, a MOAB from Modern Warfare 3. It is the highest scorestreak in the game.

Trivia
 * The swarm in the multiplayer reveal trailer looked very different to the current swarm. In the trailer the drones were not painted and has a metallic look.
