Client script with a button that creates two light sabers in front of user. Each can be taken be a different person, like dueling pistols. When equipped, trigger activates/deactivates beam, along with appropriate sound.
When beams collide it makes a sound and also changes/weakens the color of both beams for 1/2 second. If beam collides with location of head when not in weakened state, a 'hit' sound is made.
Attractive models and animations.
