If you haven't fought yet, Modern warfare will give you that opportunity. Choose a mode: passing levels or combat mode. In both, you need to collect tokens, build barracks and advance in the rank of commander in chief. Send warriors you attack to win and move on. Collect tokens on the battlefield and buy planes and tanks to strengthen your army. Increase the number of soldiers, otherwise the opponent will break you. In combat mode, your hero can control the robot and lead the fighters, and in the passage mode, the soldiers themselves will figure it out on the battlefield in Modern warfare.
