Sunborn Unveils Reverse Collapse F, a New Sci-Fi Shooter Set in the Girls’ Frontline Universe

Sunborn Network, the studio behind the Girls’ Frontline series, has officially announced a new project titled Reverse Collapse F (Foxtrot). The reveal took place during the Girls’ Frontline 10th Anniversary Music Carnival in Shanghai, China.

A Dark Sci-Fi World on the Brink of Collapse

Reverse Collapse F is set in a bleak, futuristic world shaped by the spread of mysterious Collapse particles. These elements have devastated the planet, leading to global conflict and pushing humanity to the edge of extinction.

The story goes beyond a typical post-apocalyptic setting, introducing themes such as “False Gods” and distorted spacetime. Players will take on the role of members of a group known as the “Blessed,” fighting to resist extinction and uncover the truth behind the world’s collapse. Early details suggest a strong narrative focus will be a key part of the experience.

Third-Person Co-op Shooter Gameplay

In terms of gameplay, Reverse Collapse F is being developed as a third-person co-op PvE shooter powered by Unreal Engine 5. Players will be able to form squads—reportedly up to four members—and take on missions against a variety of enemies.

The cinematic trailer showcased detailed environments, explosive combat sequences, and character animations. Brief gameplay snippets also revealed smooth movement and gunplay in dark, atmospheric settings, likely captured from a PC build.

An Ambitious Project with Deep Roots

Reverse Collapse F is currently targeting a 2028 release window. The project is also connected to Sunborn’s earlier titles, including Bakery Girl and Reverse Collapse: Code Name Bakery, expanding on the studio’s established universe.

Although still in early development, Reverse Collapse F is already shaping up to be one of Sunborn’s most ambitious projects to date, combining narrative depth with modern co-op shooter gameplay.
