After players put on their game packs, the game is started by the central computer and the players move into the arena.
After about 20 seconds, the packs will activate allowing the player to fire their phaser at opponent packs and arena devices such as base stations.
Each pack has sensors on the phaser, the shoulders, the back, and the front of the pack.
Zapping these areas will award points to the attacking player while deactivating the hit player for a short time.
After the game time has expired, the packs shut down automatically and the players return to the kit-up room.
Score information is downloaded from the packs to the central computer where the scores are calculated and individual player scorecards are printed
