About us

The war ended on paper. Here it never did. Nine nations fight over a world nearly 100,000 × 80,000 blocks wide, played through custom mods and mechanics that exist nowhere else.

Nothing is handed out. Every weapon and vehicle stays locked until your nation researches it, so what you carry is what you earned.
