3 Days War
SteamIn 2069, humanity discovered a high-energy density mineral, the Black Stone. Countries vied for control of this resource, leading to conflicts that culminated in a global war in 2085, known as the First Black Stone War. Five years after the war began, humanity developed the Core-Gear, a giant war machine powered by Black Stone. Its immense combat capabilities had an immediate impact on the war, and within a year, the world briefly returned to peace. The world split into three major factions: the Black Eagle Union representing democracy and freedom, the White Bear Front representing the people, and the neutral Suzaku Covenant in the East. However, true peace never arrived, and the crisis of war continues...
Innovative Real-time 4X Game A creative fusion of RTS and 4X core experience, with real-time battles and minimalistic operation, allowing players to focus more on development, strategy, and social interaction.

Grid-based strategic rules Expansion, construction, development, and battles occur in real-time and intuitively in the "grid". A large battlefield composed of over 10,000 grids supports dozens of players to cooperate and compete.
