ANALYZING… FILE TYPE: Status Report PERIOD: Colony Era SPEAKERS: Song, C. [ID: CSNG], Wells, M. [ID: MWEL] TOPIC: Contagion Research SUMMARY: A recording of Dr. Clarissa Song and her technical assistant, Molly Wells, discussing novel contagion research. =================================================================== [CSNG]: This is… Dr. Clarissa Song, beginning status report. My eyelids feel like sandpaper. Limbs are heavy. Heart is heavy. [CSNG]: This morning, we split one set of rations between us. Algae tea. Paste, the cheese flavor… [MWEL]: I like the honey oat one. Tastes more like breakfast should, you know? [CSNG]: I… I have with me Molly Wells, my tech assistant. [MWEL]: Not to interrupt, but could I take a look at the newest contagion analysis? [CSNG]: Ah, sure, if you can make sense of it. [MWEL]: This rate of neomorphic mutation is… [CSNG]: Impossible? Yeah, that's what I thought. But every analysis gives the same result. [CSNG]: What's more, two centrifuges are offline after leaking superheated gas. There was nothing inside that could've caused such a strong exothermic reaction. Just the contagion samples. [MWEL]: Must be a maintenance oversight. I'll request a crew to— [CSNG]: Ah, beat you to it, kiddo. Already checked the logs; everything was perfectly normal before those samples went in. [MWEL]: So… what? Our tiny volume of samples spontaneously combusted? [CSNG]: They did today. A week ago, we had software errors every time we tried to run analysis. A week before that, samples congealing into non-Newtonian fluids. Every result is impossible and impossible to replicate. [MWEL]: Can't replicate anything, can't form a coherent theory—we're no closer than we were at the start! At this rate, it'll take a miracle. [CSNG]: Well, I'm short on those. I hope nobody believed the propaganda on our way here. Colonizing an exoplanet was never gonna be easy, but Tau Ceti… [CSNG]: Maybe it's more than we can handle. Maybe it doesn't want us here. [MWEL]: You sound like Darius. [CSNG]: Well, before the admins took him offline. [MWEL]: Let's go for a walk. [CSNG]: You think I'm going crazy. [MWEL]: I think you've been staring at that screen all night. Let's stretch those legs. I have coffee back in my room. [CSNG]: You're kidding. Who did you murder for coffee rations? [MWEL]: Nobody important. Come on. Maybe Tau Ceti doesn't want you here, but I do. [CSNG]: Molly… [MWEL]: What? Why are you looking at me like that? [CSNG]: Your nose. It's bleeding. =================================================================== TYPE: TEXT [X]; AUDIO [X]
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.
