Two years before war broke out in Europe, the countries of Asia faced armed aggression. Japan's attempts to build an empire in China and neighboring countries plunged the region into a protracted war of attrition, leading to the collapse of many regimes.

Focusing on the countries of Asia, No Compromise, No Surrender offers new game mechanics, deeper strategic possibilities, and a historical flavor to nationalist and communist China, Japan, and many other countries.
