Datamine
The CAT Blue Protocol client stored some rather interesting information which turned out to be rather valuable. Due to the nature of this information, we cannot present any building or player models except text-based information.
ALL INFORMATION IS NOT FINAL. SOME FEATURES MAY NOT BE AVAILABLE TILL LATER OR NOT AVAILABLE AT ALL.
Creating a “Guild”

We were already aware that some of the UI was translated in English, but the data itself was also available in English to read. The first datamined information that we can see is related to creating guilds and managing their data.
Player versus Player (PVP) Content


There were some hints in the files related to PvP information and the several modes available. We can see that Domination and Payload are types of PvP encounters. Additionally, Bounty can be referred to as another possible PvP setting. Perhaps open world references or PVP points. To note, the PvP MiniMap data did have the map meshes available. But for safety, we cannot publish that information.
Available NPC Shops and Locations

Quite a few of the NPC’s were not available during the CAT. Here we can see the different kind of assets for the possible upcoming NPC’s in the main town. To note, the colosseum is in reference to the arena. This is where you will be going to PvP for selected modes. There are also unknown NPC’s such as MQ008 in the asset files.
Imagine (Pets) – Possible Mounts

Information was located on the possiibility of using your Imagine’s as mounts. We see MountFall and MountLanding data.
