List of Halo Levels
From Halopedia, the Halo wiki
Here, we list the levels in Halo: Combat Evolved, Halo 2 and Halo 3.In each level's page, there is a walkthough, usually for Legendary difficulty, which should also work on easier settings. Each page also contains transcripts for the level, if applicable. For a guide on writing a walkthrough, see Help:Level Walkthroughs.
