Call Of Duty : Modern Warfare 2
To use the Predator Missile, the player is required to select the killstreak from the inventory, then, after acquiring a 5 kill streak, (or 4 with the Hardline perk enabled) the player has the option to bring out a laptop. Using this laptop, the player controls an air-to-ground missile, shifting viewpoint to that of the camera on the head of the missile until the missile detonates. Enemy players will be outlined with a red square on the missile's camera. In multiplayer, however, enemies using the Cold-Blooded perk will not be outlined by a red square. The Predator Missile is shown on both teams' radars.
Pressing the fire button while the missile is traveling to its target fires the secondary thrusters, making the missile move faster but decreasing its steering ability considerably. This is somewhat more noticeable in campaign than in multiplayer. Using the boost can be crucial when many targets are close together, as they may scatter if the missile does not hit in time. However, some players always use the boost immediately, which is inadvisable as it can prevent them from getting a good view of the battlefield and accurately selecting the best target zone.
