A Korean turn-based mobile strategy RPG developed by Sigma Works and published by Valofe (formerly Smartjoy) in South Korea, and elsewhere by VFun. The game was launched in January 2019 in South Korea, followed by Japan in 2020 and global version launched in 2026.
The game's setting is a world where human civilization has crumbled. The remaining human survivors work together with Auto Guard System (AGS) robots and artificial humans called Bioroids to defend the planet against the Ironworms, alien parasites of unknown origin.
The game became popular (as well as infamous) upon release thanks to its many suggestive character designs during its introduction by regular artists such as Snowball and Kakiman, as well as collab artists Asanagi and Obui. After the release of the adult-only "R+" version in August 2024, the game has since introduced numerous sexually explicit character design and skins.
