ANALYZING… FILE TYPE: Inter-Corporate Transmission PERIOD: Present Day SPEAKERS: Analyst [ID:MVAL], Engineer [ID:TSIT], Nona [ID: NONA], Scientist [ID: RRES] TOPIC: Thank You SUMMARY: A personal transmission from Nona and the Sekiguchi team working on SIMbiont iteration. Per CyberAcme corporate policy, this content has been scrubbed for potential infosec hazards. =================================================================== [NONA]: Runner, I've assembled several leads from Sekiguchi's biosynth engineering team. They wanted to personally thank you for your efforts. [TSIT]: Honestly, what you've done is career-changing. I couldn't sleep after refreshing the Tau Ceti data feed. [RRES]: It's so gratifying to see our theories and hard work put into practice. [MVAL]: Nona said we were getting the best on board, and she delivered. [RRES]: Incredible rate of iteration. Inspiring, really. So much faster than we could do at home. [MVAL]: We couldn't dream of this kind of pilot study on Earth or Mars. So many limitations on study size, participant comfort, "acceptable side effects," on and on! [MVAL]: But you've got no bureaucracy to slow you down— [TSIT]: Anyway, the team is brimming with ideas for future SIMbiont research. You should hear us argue! [MVAL]: You should see the funding numbers. [NONA]: They're such bright, lovely people. [NONA]: I think it's important to maintain emotional resonance between us in Sol and you on Tau Ceti. I refuse to leave Runners adrift among the stars. [NONA]: Remember, small beginnings seed great things. Small beginnings bend the arc of progress to our will. [NONA]: Take pride in this moment: a beginning that you brought to fruition. [NONA]: From all of us at Sekiguchi Genetics… thank you. ALL: Thank you! =================================================================== 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.
