The Cobalt Protocol Revamp is bringing you a whole new experience.
Sometimes, revamping an existing mode is harder than creating a brand-new one. While we’re excited about what’s new, we completely understand the sense of loss longtime Cobalt Protocol players might feel. Honestly, even among our own team, those who loved the original mode felt conflicted about this decision.
But the truth is, Cobalt Protocol had long reached a point where it was difficult to maintain. It was designed as a light, beginner-friendly way to enjoy Eternal Return, but in practice, many new players ended up leaving after trying it. As Lumia Island gradually shifted in a more casual direction, Cobalt Protocol’s place within the game became even harder to justify.
So instead of letting it slowly fade away, we made the tough call to go all-in on a full revamp. We’ve done our best to preserve the spirit of what made Cobalt Protocol special, but also aimed to make it more accessible and casual, following true to the idea of a “light mode.” In doing so, some of the detailed mechanics from the original have been set aside.
We’ve received your feedback regarding the removal of the Random Character Selection system. While it was a unique feature of Cobalt Protocol and could be a strength for players familiar with Lumia Island, it often became a significant barrier for new players and discouraged them from trying the mode. We understand concerns about premade team compositions follwing the change to free character selection. However, 4P Premade Teams will now only be matched against other 4P Premade Teams, and with more frequent balance updates, we believe this will help address the concern.
We’ve also heard that the mode still feels complex. Since game depth is closely tied to long-term enjoyment, we did not want to remove it entirely. Instead, we focused on refining the experience so new players can approach that depth more naturally. We have maintained the depth of combat while restructuring non-combat elements to be more intuitive.
After Official Launch, Lumia Island also went through some early growing pains, but gradually improved through steady updates. The Cobalt Protocol Revamp is on a similar path. We’ll keep adjusting and improving through trial and error to ensure it becomes what it’s meant to be, a true light mode for Eternal Return that’s easy to pick up and fun for everyone who tries it.
We hope you enjoy it!
And as always, thank you for sticking with us.
