In December, we shared a new look at Marathon in our ViDoc , where we dove into things like immersion, zones, new features since alpha, and more. Today we want to share more about Runner shells, the moddable biosynthetic bodies you'll inhabit on your runs to Tau Ceti. You can watch the full video now.

Runner Shells: Tools for Survival
As a Runner, you've sacrificed your physical form and transferred your consciousness into a biosynthetic shell designed to help you survive Tau Ceti—or at least make it so dying isn't a permanent affliction. Each Runner shell is built around a different gameplay archetype, such as intel gathering, combat disruption, or combat healing. With distinct silhouettes, shells allow you to evaluate player threats and strategize your next steps on the fly. Each Runner shell's playstyle can be customized using the cores, implants, weapons, and mods you bring on your runs. We'll talk about the ways you can customize your shells visually in the future, including more details on the earnable cosmetics you'll unlock through the Codex and other ways.
