With Sky Blaster's 4-Blaster Laser Tag set you can organize a game of laser tag with four friends and enjoy hours of fun. These blasters light up and vibrate with each tag and have an array of sounds for added excitement. Every game you play can feature up to four teams with an infinite number of players on each (must purchase additional sets). Every blaster features nine lives per games, a team selector button, and reload button. The built-in receiver/transmitter allows you and your teammates to battle from over 130ft away. Let the battle begin!
