There are 3 different settings for how your laser shots are fired which can be changed throughout the match. Each setting has different strengths in terms of distance, power and time to charge. At the back of the rifle is a secret weapon button for the ultimate attack, but think twice because it can only be used once. In the front there is an infrared 180 degree receiver that detects if your weapon is hit - so you do not have to wear a vest. So you can be hit both from the front and from the sides so you have to be vigilant.The weapons work up to 30 meters. 6 AA batteries included.
