Bzzzzz, Bzzzzz, your vest is vibrating, your heart is pounding and the adrenaline is coursing through your veins. You’ve just been hit and take a moment to recover behind a barricade, but the game is on the line and you can’t stop now. You hear the enemy advancing in front of you and know this is your chance. You pop up from behind the cold dark barricade and take aim, steady yourself and fire. A red beam flashes out from your blaster and strikes your opponent right in the chest. The enemy falls silent, looks up at you and in a state of shock whispers just loud enough for you to hear, “Mom!” Game over, you win, you win!
