Duino Tag Modifications

Hi everyone, I am currently working on a project where I am modifying the base design of duino tag to create a new game. My group is trying to create a western style duel sort of game where the arduino uno on each player beeps, signifying them to draw their gun and shoot the other person. Once one player is hit the player that was hit will light up and both player's sensors will turn off. Is there any way to wirelessly or bluetooth connect the two arduino uno boards so that they play the start sound at the same time and so that they can signal to the other board when to stop the game? I really appreciate any help or ideas!

Is there a link where we can read about "duino tag" and see the code?
