Battle Cry! is a man-to-man wargame covering infantry battles on a tactical level between US Marine units and the Imperial Japanese army units. The scale is 10 meters from hexside to hexside and each counter represents a single infantry.

Four maps are provided which simulates the typical terrain found in the Pacific War. The maps include a beach map, jungle map, mixed terrain map and rough terrain map.

Each individual unit has a performance rating (PR) which requires that a performance check (PC) be made before moving, firing, observing or assaulting.

The advanced game includes armoured fighting vehiches (AFVs), crew-served weapons, anti-tank weapons, mortars, flamethrowers, mines, hidden units and more.
