It was designed for the game Laser Invasion, but works with any game compatible with the NES Zapper. In the United States, Laser Invasion came with a coupon for a $5 discount for the LaserScope.
It is voice-activated, firing a shot whenever the wearer says "fire" (although some reviewers criticized its ability to do so). The headset also includes an eyepiece with a crosshair that sits in front of the wearer's right eye.
The LaserScope is powered through the audio port of the NES, allowing it to function as headphones for the NES.
The LaserScope received negative reviews for its poor microphone technology; users complained that saying anything into the microphone would cause the LaserScope to fire, including background noise.
