Terminal

Terminals are objects found in Halo 3 and Halo: Combat Evolved Anniversary. Conceptually based upon similar terminals in Bungie's earlier Marathon game series, the Terminals fill the player in on the Halo backstory.

Halo 3


The Terminals in Halo 3 are in textual format, similar to the Terminals in Marathon. They are a continuation of the Iris alternate reality game used as viral marketing for Halo 3. They clarify a great deal of the Iris storyline by naming the authors of different messages and by explaining the circumstances of the original firing of the Halo Array. The Terminals follow the stories of the Librarian and the Didact, Forerunner logs of Flood attacks, and Mendicant Bias's progression into rampancy.

Halo: Combat Evolved Anniversary
The Terminals in Halo: Combat Evolved Anniversary feature fully-animated cutscenes instead of text like in Halo 3. Most of them are logs narrated by 343 Guilty Spark and expand on the history of Installation 04. They also have connections to the stories of The Forerunner Saga and Halo 4.
