No-Fly Zone

No-Fly Zone is an achievement in Halo: Combat Evolved Anniversary that is awarded for destroying three of the four Banshees in the level Halo. It is represented by a Banshee inside a reticule, with "3" overlaid on it.

The achievement is worth 10 Gamerscore points.

Tips

 * Note that it has to be the player who takes down the Banshee, and not an AI Warthog gunner.
 * In the beginning of the level, there are two Banshee. When one of them is destroyed, the other escapes. It is recommended to shoot both of them until they have smoke coming out of them, and then take one of them down. Even if the second one can evade Assault rifle fire, it won't be able to evade pistol shots.
