Daisenryaku II: Campaign Version is a turn-based war strategy game that relies on the gameplay template introduced in Daisenryaku II: up to four players engage in battles against each other or computer AI, represented by differently colored armies (blue, red, green, and yellow), the belligerents produce units and vehicles and navigate them on a hex-based grid, trying to occupy the enemy's major cities and harbors. The game includes a main campaign with introduction and background information about the fictional countries involved in the conflict. In addition, at least a dozen playable maps are included, some representing real geographical areas. The MSX and PC Engine (TurboGrafx) CD versions feature enhanced graphics, full-screen battle sequences with backgrounds, and many additional maps.
