Each unit is fitted with either a 30mm red dot 'fast target acquisition' sight or a telescopic sight. The red dot sight has the advantage of being easy to use for 'point and shoot' in close quarters combat. The telescopic sight has the advantage of being more precise for log distance shooting and 'sniping'.

Each gun is configurable with from 1 to 99 hit points. Each time you are shot, you lose a hit point (life). The number of hit points issued to players by a marshal at the beginning of a game varies from mission to mission. When you lose all of your hit points a voice from your gun will exclaim "aarh!", a sensor that you wear on a cap on your head will glow red, and a display on your gun will tell you that you are 'dead'. Guns are reset at the start of each mission by a marshal.

There are 2 sensors attached via a cable to the gun, these sensors are worn by the player on a cap. The sensors can detect the infra-red pulse from another gun in a 180 degree arc, so you can effectively be shot in the head from 360 degrees. There is also a sensor on the front of your gun. When shooting at an opponent, you aim for the front of their gun, or their head.

When you pull the trigger, the gun emits an infra-red beam detectable by the sensors worn by the other players, and your display indicates you have one shot less in your clip. When you reach 10 shots left in the clip, a voice from the gun warns you that you are low on ammo. The gun makes a clicking sound when you have run out of shots. To reload you press the forward button under the carry handle. There is a 6 second reload time, and when you are shot and lose a hit point, your gun will be disabled for 3 seconds.
