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:
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.

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

Version 4.0 is also expected to introduce new gameplay systems.
While details remain limited, leaks suggest the update may include:
More details will likely become available closer to the official Version 4.0 announcement.

The current community consensus is that Anna and Lucille are expected to be the first major New Federation characters.
Character | Expected Version | Current Leak Information |
|---|---|---|
Anna | Version 4.0 | Rumored New Federation 5-star character, described as a noble-blood character |
Lucille | Version 4.0 | Rumored female 5-star character, often described as a cat-girl style character |
Lucille has also appeared in previous New Federation discussions, with existing lore connecting her to Startorch Academy.

Version 4.1 is expected to continue expanding the New Federation lineup.
Character | Expected Version | Current Information |
|---|---|---|
Aimoshesh | 4.1 | Rumored anti-resonance humanoid mecha character, possible DPS role |
Mecha Male Character | 4.1 | Possible Calcharo SP-related character with a half-mask/mecha design |
Aimoshesh is one of the most discussed characters in current leaks. Community speculation suggests:
However, these details remain unconfirmed. The rumored mecha male character has also created discussion because some players expect a possible Calcharo SP form, although this conflicts with other SP rumors.

Beyond 4.0 and 4.1, more New Federation characters are expected.
Character | Expected Time | Current Information |
|---|---|---|
Christine | Around Version 4.2 | Rumored female celebrity / “extraterrestrial satellite girl” |
Former Military-Police Instructor | Unknown | Part of rumored New Federation lineup |
Museum Curator / Director | Unknown | Character details unavailable |
Grid / Pigeon Detective | Unknown | Character details unavailable |
Christine is one of the most talked-about future characters because she has appeared repeatedly in New Federation-related discussions.

The New Federation Sentinel Prometheus has been referenced in previous lore content, including NPC dialogue connected to Lahai-Roi. Current theories suggest Prometheus may become an important figure in the New Federation storyline.
However, there is currently no confirmed information about:
Players may learn more once Version 4.0 story quests become available.

With several rumored 5-star characters arriving in the 4.x cycle, resource planning will become increasingly important.

Priority | Recommendation |
|---|---|
Save Astrites | Avoid unnecessary pulls if you want New Federation characters |
Farm Materials | Prepare EXP, Echo, and upgrade materials |

Wuthering Waves 4.0 is expected around late December 2026, following Version 3.8.
The New Federation update is a major expansion expected to introduce a new region, exploration systems, vehicles, and multiple new Resonators.
The current leaks suggest Anna and Lucille will be the main Version 4.0 characters.
Anna is currently a community leak and has not been officially confirmed by Kuro Games.

If you are interested in Anna, Lucille, or later 4.x characters, saving Astrites is recommended until official information is released.
The Wuthering Waves New Federation update could become one of the biggest expansions in the game, introducing a new region, exploration changes, and many new Resonators.
