World War II:1939 is a 3D role-playing game set against the backdrop of World War II. Players engage in a classic capture-the-flag simulation battle, choosing to play as either the red or blue team. The objective is to capture strongholds and fortresses through defense strategies, depleting the opponent's strength value to secure victory.

The game features ground vehicles like the M4 Sherman tank and Type 89 tank, along with AI air support vehicles such as the P40 fighter and A6M-Zero fighter. Infantry weapons include a variety of rifles like the Springfield, Type38, Mosin-Nagant Rifle, and Mauser. Future updates promise to introduce a wide array of aircraft, tanks, personnel carriers, artillery, and more.
