If you've dug into the starter pack for LEGO Dimensions I'm assuming you're wondering why there no instructions present for it. Instead of being included within the game itself, most of the instructions for LEGO Dimensions are included in the game when you play it or randomly during levels when it's required. With that I've produced a video of Batmobile instructions so you can build the vehicle without playing the game for whatever reason you need to. May add picture instructions later, though the video is what I have time for currently.
