After you have begun to master the game with one laser, can you up the ante and handle three? The Eye of Horus beamsplitter piece splits one laser beam into two when hit by reflecting half of the beam and transmitting the other half right through for twice the strategy and excitement! With both pieces in play, the beam can be split twice blasting three lasers around the field with one push of the button! Each expansion pack includes two Eye of Horus Beamsplitter pieces, one silver and one red, and a full color booklet including brand new starting setups and science explanations.
