Lego Batman 2: DC Super Heroes Walkthrough Part 11 – Asylum Assignment, Part 3
With the Sensor Suit on Batman head back into the Security Corridor. Cloak and head to the North . Just as you enter the corridor you will find the switch to turn off the cameras on the left. Once they are down, switch back to Robin and change him back into his Ice Suit. Use this suit to extinguish the flames that are blocking your way forward. Head to the end of the security corridor and turn to the right there. Head into the X-ray room and take down all the minions waiting inside for Batman and Robin. It only takes a moment anyways.
On the other side is a massive room filled with about 10 minions who are scattered about. There are 6 immediately around you though. Beat them up then there is a little more to do before moving on. Head over to the smoothed-out stairs with Batman in the Sensor Suit. Head to the center and interact with it to reveal 3 switches inside. Set them so each lights up green. The left-hand switch is green in the middle, while the middle switch actives on top and the right-hand switch actives on the bottom. With those in the right positions, a bridge will activate to the right. Be sure that Robin is with you in his Ice Suit.
Cross the bridge and there will be a good 8 goons coming at you. Defeat them then focus on the moving water that is nearby. Switch to Robin and use his Freeze Ray to create a climbable wall on the right-hand side wall with the waterfall. Deal with the one inmate who is at the top then head over to the left and throw the switch there. It will complete the next bridge you need to cross.
On the other side, you have an initial 3 inmates to deal with. After that, hop the fence and Scarecrow will send a large number of minions at you. There are 10 – 12 to deal with on that side so be ready for a fight that lasts a moment.
With those minions dealt with, head over to the steel wall over on the left. It is time for another sequential X-Ray puzzle. Have Batman attune to the surface than look in the upper left. Interact with that piece first, the battery. Follow it as drops and rolls some to the right. Look a little down and to the right from there to find the next piece that needs to be dealt with. Do so 3 times to get the battery to roll all the way to the end of the ramp. Look just a little to the right to see the battery come to rest in an elevating cradle. Interact with it to raise it up. Follow the battery up and, at the top, a little to the right. There you will find 2 final pieces to move. Do so to get the battery to drop down and into socket it needs to be in.
This powers up the stairs and clears the way over to the Scarecrow above. Take the stairs on up to deal with 4 inmates as you ascend. Take them out then switch to Robin and approach the flames to put them out. As you head toward the flames, 2 inmates will attack. This is followed by 2 sets of 4 inmates a little farther in.
After all that, you will reach a gas barrier blocking you from the Scarecrow. Head over to the left-hand side. Just above the gas pipes is a bar. Have either Batman or Robin jump and grab onto it. This will reveal a switch on the right-hand side of the gas barrier. Have the other go and throw the switch to shut down the Gas Barrier.
