LEGO Batman 2: DC Super Heroes 3DS Cheats and Tips

Fly up really high as Superman. When you see a bunch of red spotlights, go towards them and drop. You need the heatray to break locks or Flash's super speed. Press B when you get close and the map will get cleared a bit and a villain will appear nearby. Hope this helped!

You buy the DLC

You should use The Joker.

If it's the Scarecrow on Story mode you have to get up onto the sides and turn on the giant fans to empty out the gas. If it's the Scarecrow in the open world inside the giant pumpkin, you have to destroy the things pumping out the fear gas on the walls.
