Phoenix Logs

''This is a word-by-word replication of the original collectibles found in Halo Wars 2. As such, any errors or irregularities are simply carried over from the original game.''

In Halo Wars 2, Phoenix Logs are a collection of codex entries that provide background information on units, characters, and other events of the Halo universe. Much like its predecessor’s collectible Black Boxes, which unlocked Timeline entries in the game, the Phoenix Logs can be unlocked by both feats of completion as well as collection and be accessed from the game’s campaign menu.
