Battlefield is a digital battle game where teams with infrared weapons and equipment are trying to outdo each other with their planned strategies and performances. The feature that distinguishes this game from paintball is that instead of using guns that shoot paintballs, participants use lasers that will let off a warning sound when hit. The system automatically detects those players that have been eliminated and locks their devices. Team members include the leader, sniper, watchman, trailblazer, etc., and these members work together to try to completely neutralize the opposing team and the battle tactics they employ. The goal is to work as a team to reach the respective goal in various scenarios, such as the capture of the opponent team, hostage operation, and ambush. Since guns do not throw a physical object like bullets, there is no risk of injury to the players and therefore there is no obligation to wear a protective mask / vest during the game.
