The gun has a 360-degree sensor worn around the head that detects hits to the player’s body. On the side of the gun, there’s an electronic display showing your number of lives, ammunition bullets, how many opponents you’ve hit, how many times you’ve “died,” and your remaining magazines.

Each time you’re hit, you’ll feel a small shock/vibration on your head and hear “I’m wounded,” while your life count decreases.
When you hit someone, you’ll hear a confirmation sound, and if you hit the head, you’ll hear “Head shot.”
When a bullet passes close by, you’ll hear the whizzing sound of it passing near you.
Once all your lives are gone, the gun automatically shuts off, so no space for cheaters 🙂
