Lego Batman 2: DC Superheroes Walkthrough Part 17 – Chemical Crisis, Part 5
In the next area, it is time for some more puzzle solving. First, before going down the stairs, there are some lockers that have light coming from them. Destroy them to get some assembly pieces for a Suit Changer for Batman. This will give him the Power Suit again. Use it to blast the silver bars in front of the Suit Changer for Robin so he can get at his Hazard Suit. As Superman, approach the reflective brinks to the left of the orange chemical flow. Concentrate on the green brinks to reveal the next X-Ray puzzle. Beneath each of the contains is a wheel switch that needs to be thrown. Okay, with the all set-up complete, it is time to work on the puzzle some.
First, hop down to the lower level of this area as Robin in his Hazard Suit. There you will find 3 pits, though only one has a colored chemical in it. Get into the pool of the chemical and fire it into the middle pipe to fill the tank. After it is full, get out of the pit, take the stairs up and head over to the right, below the huge vat of green chemicals. There you will find a pit filled with the Green Chemical. Hop into the pit as Robin and fill the tank. Once it is full, head back to the lower area and pump the green chemical into the left-hand side pipe. Once that one is full, it is time to move onto the final color. Head back to where you found the Green pit, but continue to the right to find the final, purple pit. Fill the Hazard Suit's tank and return to the pipes. Put the purple chemical into the pipe on the right. This will then change the chemical spouts into water spouts.
Change over to Batman and head back to the Suit Changer. Have him get into his Electricity Suit again and head over to the Water Spouts. Next, use Superman to freeze the spouts so both Batman and Robin could climb them easily. Still, just Batman to pass through the electrical barrier that is at the top of the ice stairway. From there, have him pull all the power from the generator in the center of the floor. It will shut down the electrical field that is keeping the other 2 out.
Now, switch to Superman and fly up to the next level. There you will find a Gold Brink panel that will pulse a shape just above the raging fire to the right. Have Superman trace out the shape there to release the needed water to put out the fire.
With that, head to the right. As you cross the next catwalk it will collapse beneath you. As you finish crossing, 3 henchmen will attack. Deal with them then head forward to the right. There you will find a zig-zagging line of chips leading up. Change to Superman and follow it up to the Gold Panel. Use Heat Vision to trace out the hole. This will unleash a torrent of water which Superman can then freeze, allowing the Duo to climb up to the next level.
At the top, switch to Batman and head to the right. Just to the left of an elevator you will find a generator that needs some power. Have Batman power it with the charge he pulled a little while back. Take the elevator to reach the next part of the stage. When the elevator reaches the top, head to the right to find a Save Station.
