A fan game-turned-official announced during MICA Team's 4th Anniversary Stream, May 15, 2020. A top-down side scrolling pixel-based adventure game set to star HK416 as the main protagonist, set before the beginning of the core Girls' Frontline story. Other characters that were slated to appear, aside those original to it (i.e. Anna, a SF researcher, and unnamed characters from its teaser), included Thunder (wearing a labcoat) and M870.
Was announced to be shelved on February 11, 2021, a victim of increasing regulations on game registration in China (including the suspension of the approval of newly registered gaming IPs) preventing the game's release, with the original creator leaving Sunborn amicably and speaking favorably of his time there.
