Ambient AI

Ambient A.I. are Artificial Intelligence ingame in Halo 3 that have a programmed animation that confines them to a certain area which they can not leave. For the most part, they ignore the player unless approached, and can be killed just like any other A.I. Instances that include them are the Technicians in Crow's Nest, the wounded Marines in Tsavo Highway and The Storm, the Banshees and Hornets in various levels, and the Final Grunt, among others. They are not featured in Halo: Combat Evolved and Halo 2, except for the Thirsty Grunt in Halo CE and the Cowardly Grunt in Halo 2. These AI are not to be confused with the AI characters like Cortana from the games and books.

Killing ambient A.I. does count against your Meta-game score if you kill marines or Elites, however killing ambient banshees will add points to your Meta-game score.
