Batcave | Walkthrough LEGO Batman 3 Guide
Last update: 11 May 2016
When you resume control over characters, select Batman and put on the Sensor Suit. Approach the wall next to you and arrange the brick at their places. You will also find a switch in the middle, which unlocks a nearby locker.
Approach the now unlocked locker and collect a Batman's token (Power Suit). Smash all the objects on the platform (you can use explosives for that). The next step is building a mechanism out of bricks lying on the platform.
Once you have built the mechanism, approach it and turn it left. This way you extend a platform that allows you to get to the other side of the room.
When you get to the other side, wear the Sensor Suit and turn on invisibility (hold the interact button). Now you can enter the room ahead of you without being spotted by the camera. At the end of the small room, change to the Power Suit and plant a bomb on the locker. When it blows, approach the lever there and pull it.
When the security system is off, switch back to Robin, then enter the small room and destroy all objects there. One of them drops a Robin's token (Techno Suit)
Once you have collected the suit, approach the main panel as Robin and use it. The picture above shows the part when you have to match colors of the central square in each column with the colors of the squares on its either side. Place the cursor over the central light in the left column and wait until it changes its color to the one on its either side, then press the correct button. Repeat that for all lights in order to unlock the elevator next to you.
