Play solo, head-to-head or in “Co-Op Mode,” where two players team up to get the highest combined score. Just set the ProjeX game arcade base on a low table, with the projector heads aimed at the wall, load 1 of the 3 included Target Slides and select the game you wish to play! The projector should be 5 feet from the wall and works best on a light-coloured wall. Set includes 1 x ProjeX Game Unit, 2 ProjeX Blasters, 3 x Target Image Slides and 1 x Instruction Leaflet.
