As for CODEX’s new form, the devs are working on releasing a public server that will let users host MMOs, as well as a world builder tool and additional features like multi-story buildings and network optimizations. In the future, CODEX plans to arrive on Steam and open up testing, though some networking tests still need to be performed before signups begin. Until then, future updates are planned to be shared on CODEX’s new website.
