Ghost (perk)

Ghost is a Tier 1 perk in Call of Duty: Black Ops. It is roughly equivalent to the UAV Jammer, Camouflage, and Cold-Blooded perks from past Call of Duty games.

Overview
Ghost prevents players from being shown on radar when an enemy Spy Plane is in the air. Its Pro version prevents Sentry Guns and Attack Helicopters from attacking the player. In addition, it removes the red box that marks targets for Valkyrie Rockets, the Chopper Gunner, and the Gunship. It also prevents the player from glowing white in the Infrared Scope. As a final effect, the red cross-hair and name do not appear when an enemy aims at a player using Ghost Pro.

Contrary to the in-game description of Ghost, neither Ghost nor Ghost Pro will protect the player from a SR-71 Blackbird, Dogs nor from the Motion Sensor.

Ghost gives the player model a ghillie suit or hood, depending on faction.

Pro Challenges

 * Concealed Kills – Kill 20 enemies while they have a Spy Plane or Blackbird active.
 * Destroy Aircraft – Destroy 30 aircraft with any non-Killstreak launcher.
 * Destroy Sentry Gun – Destroy 1 Sentry Gun.

Tips

 * If you are having a hard time finding an enemy Sentry Gun to unlock Ghost Pro, try earning a Sentry Gun as your own Killstreak and let the enemy capture the crate. Also the Hacker perk allows the player to find sentry guns with ease.
