Ambient A.I.

An Ambient A.I. is an artificial intelligence in-game in the Halo games that have a programmed animation that confines them to a certain area which they cannot leave.

For the most part, they ignore the player unless approached, and can be killed just like any other A.I. enemies or allies. 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.

There are a few featured in Halo: Combat Evolved, such as the Thirsty Grunt and the Paranoid Marine, and the Cowardly Grunt in Halo 2. These AIs are not to be confused with the A.I. characters like Cortana from the games and books.

Killing an ambient A.I. counts against the Metagame score if the player kills Marines or Elites, however, killing ambient Banshees will add points to the Metagame score.
