About Codex in Marathon
The Codex is one of the most important progression systems in Marathon because it keeps track of the things that stay with your account over time. It covers achievements, collections, lore entries, cosmetics, titles, and other rewards tied to what you do in the game, and you can check it outside of your runs.
What makes the Codex stand out is that it is not just a lore menu. Marathon connects it to contracts, narrative items, and other in-game milestones, so the more you explore and complete, the more entries and rewards you unlock. It also carries over between seasons, even when things like gear, faction progression, contract progression, and player level reset.
