The biggest feature of Version 4.0 is expected to be the official opening of the New Federation region.


Unlike previous areas such as Huanglong and Rinascita, New Federation is expected to focus more on:

  • Advanced technology
  • Industrial environments
  • Modern cities and machinery
  • New exploration methods


The New Federation has already been mentioned in existing lore as a highly developed technological nation. Its storyline is expected to expand on themes surrounding science, research, and the relationship between humans and Resonators.


2. New Exploration Vehicle: Anna Flyer

A new vehicle called Anna Flyer is rumored to arrive with Version 4.0. Although its exact functions are unknown, community discussions suggest it may become an important exploration tool for the New Federation map.


Possible uses include:

  • Faster open-world movement
  • Accessing special exploration areas
  • Replacing or expanding current travel systems


The vehicle rumor has gained attention because exploration upgrades are often introduced alongside major region expansions.


3. New Combat Mechanics

Version 4.0 is also expected to introduce new gameplay systems.

More details will likely become available closer to the official Version 4.0 announcement.
