I've played it once. All components are present. This game is a beginner (rookie) version of "Captain Sonar," a team-based game where two teams, separated by a screen, try to locate the other team's submarine and sink it with torpedoes. While the original "Captain Sonar" allowed up to 8 players, "Captain Sonar ~The Rookie~" is designed for 2-4 players, making the gameplay faster and more enjoyable. Players use sonar to locate the enemy's position and utilize silent running to avoid being detected, engaging in intense battles in the deep sea. When you think you've located the enemy submarine, declare "Fire!" and launch a torpedo. The team that scores two direct hits with torpedoes wins the game by declaring "Enemy submarine sunk!" "Captain Sonar ~The Rookie~" also includes a real-time battle mode specifically for 4 players, allowing for even more exciting gameplay.
