If there’s one thing that’s kind of confusing when approaching Fantastic Pixel Castle’s Project Ghost MMO, it’s that the studio keeps using the terms “blue zones” and “red zones” like you should automatically know what they mean. Fortunately for the non-psychics among us, Fantastic Pixel Castle has been explaining what these are in recent blog posts, including a new one this week that highlights red zones in particular.

Blue zones, you might recall, are the more numerous in the game and feature procedurally generated content that “feels handmade” thanks to a “recipe” that the studio cooked up to deliver upon a designer’s vision. They’re also private instances balanced around small parties. In contrast, red zones are the fewer, specifically developer-created regions that are more in line with what most MMO players might be familiar with seeing.

“[Red zones] are completely handmade by an artist or level designer, and they are able to portray environments that blue zones (as clever as they are) would struggle to produce,” studio founder Greg Street wrote. “Red zones are not private. Quite the opposite. We really want to concentrate lots of players in red zones, and we want to discourage players from feeling like seeing other players is a bad thing.

Street noted that the team is working to keep red zones feeling relevant and a touch dynamic. Additional effort is being made to give players reasons to go to both types of zones: “We will structure rewards and progression in such a way that players have reasons to go to both blue zones and red zones and can’t just ignore half of the game.”
