    1. Entering the Ace Chemicals building, Batman and Robin need to find five clues scattered around the area.
    2. You’ll also encounter a new hazard; puddles of chemicals. Stepping into the chemicals will hurt, so stay away.
    3. Just ahead, you can find Robin’s Hazard Suit inside a closed chamber. To get inside, just smash the Lego objects right of the chamber and build the bouncing bricks into a switch. Turn the switch, and the chamber will open.
    4. Switch to Robin, and grab the floating Hazard Suit inside. Equip it, and start cleaning up the chemical spills with a spray of water.
    5. Into the next room to your right, jump into the pool after climbing the stairs and flip the switch to raise your first clue out of the water. Make sure to use Robin’s Hazard Suit so you’ll sink to the bottom of the water pool.
    6. With the green container raised up, jump to the hand holds and interact with the white spot to get your first chemical sample. The door back in the main room on the right side will open, and some thugs will attack.
    7. Switch to Batman and beat the thugs down. Continue right to the catwalks overlooking a giant green vat of chemicals, fighting the thugs and throwing Batarangs at the pie-throwers above until you’re past the purple vat.
    8. In the next area, the elevator will crash and explode, leaving behind electric currents. You know what that means, you need to find Batman’s Electricity Suit.
    9. At the center of the room, right of the valve you can turn, are four red lit Lego objects. Break all four so that they turn green, then turn the valve to reveal a pool of green chemical. You don’t want to suck this chemical spill up, you want to clean it up.
    10. Have Robin jump into the pool of water to the right, then clean up the green sludge with a spray of water using the Hazard Suit to reveal Batman’s Electricity Suit underneath. Now you can climb the ladder in the back left filled with electric currents.
    11. Climb the ladder with Batman’s Electricity Suit equipped, then turn the switch at the top to turn the currents off, allowing Robin to rejoin Batman.
    12. Now you can easily collect the next clue. Just follow the grated catwalk left and interact with the purple container.
    13. Getting the second chemical sample will open the large underwater pipe back right near the electrified switch you just used. Fight through the thugs, then switch to Robin and his Hazard Suit to walk through the water-filled pipes.
    14. At the end of the water-filled pipes is a switch. Turn it to drain the pipes of water and open the door into a new area.
    15. In the new area, you’ll immediately spot an electrified ladder, and blue magnetic Lego bricks. Keep Robin and his water-filled Hazard Suit equipped, you’ll need the water!
    16. Run down the steps and look in the left corner, just behind another set of steps. Clean up the mess of green and purple chemicals to find a new suit for Robin.
    17. After cleaning up the spill, build the bouncing bricks into Robin’s Magnet Suit. Equip the suit, and run back up the stairs to scale those magnetic blue bricks. They’ll take you to a small catwalk above a previously unreachable area for Robin. Jump down, and use your magnet power on the blue brick in the back left corner.
    18. Have Batman with his Electricity Suit use the newly revealed switch, then interact with the chemical vat to find your fourth sample.
    19. Doing so will raise a new catwalk over the giant green vat in the background with a handful of enemies. Past them is another blue magnetic brick. Use Robin and his Magnet Suit to tug the blue brick down, revealing a ladder.
    20. Up the ladder, one of the Joker’s bombs will destroy your path forward. Simply rebuild a portion of the bridge using the bouncing bricks and jump across.
    21. Ahead and to the right, you’ll find machines moving chemicals behind a metal fence. Run into the foreground and wait for one of the chemical trays to move into position on your right, so you can leap on and ride.
    22. Jump off right over the lanes. Look for blue magnetic Lego objects in the background, and pull them forward using Robin’s Magnet Suit. Now, you can climb up to the raised area in the back ground with a few jumps.
    23. Up on the platform, you’ll also find your fourth chemical sample, orange this time. It’ll also activate more moving trays to your right down below, bringing some thugs with.
    24. Getting across the gap to your right is a lot trickier. Wait for one tray to stop, then jump off to the other and ride it until you can leap.
    25. When you make it into the area with three pools of chemicals, switch to Batman and use the electrified switch near the larger of the green chemical pools. The switch will shut down the electricity guarding the Hazard Suit for Robin right behind the switch.
    26. Grab Robin’s Hazard Suit and look at the back wall. See those three called circles against the back wall? Each needs to be filled with the appropriate colored chemical. Green goes to green, purple goes to purple, and orange goes to orange. Just have Robin fill up with each chemical, and fill each circle until the red light turns green.
    27. Once all three vats are full, the pool of green chemicals will turn into water, allowing Hazard Suit Robin and Batman to swim right into the next area.
    28. But, the hand holds to get up to the upper area and protected by electricity. Use Batman to climb up and pull the switch against the back wall up top.
    29. The electricity is now gone. Jump up with Robin and clean up the green gunk in the foreground, covering another switch. When clear, pull the switch to open the passage.
    30. With the gate open, run all the way to the right side, beating up the goons and their new forklift. Against the right wall are more hand holds that have been electrified. Jump up the pipes with Batman to reach them, then climb the hand holds to ender the gated off area.
    31. Inside the gated area, flip the switch to open the vat to your left. Climb back up and over the gate and find the Forklift vehicle.
    32. The Forklift vehicle can raise and lower its pallet, created a raised platform. Grab the Forklift and drive it over to the left side of the room. Wait for your partner to jump onto the pallet, then raise it. If you’re playing alone, the AI will jump onto the raised area for you, just hold the Forklift’s platform until it does.
    33. Attack the Lego object on the left to create a ladder. You’ll need it, after you flip the switch on the raised platform, the vat will open and allow Robin to jump into the water.
    34. In the central vat, Robin won’t be able to collect the last sample until it’s drained of water. Walk into the center of the vat and float to the surface to find a switch that will solve your water problem.
    35. Now that the chemical container is water-free, go interact to collect the last sample, triggering a cutscene and taking you to the next part of the level.
    36. An explosion has caused even more problems at Ace Chemicals. Run right through the chemical spills with Hazard Suit Robin, and break the Lego objects against the left wall near the fires until they produce bouncing bricks.
    37. Construct and you’ll fix the water pump, filling the square area to your right with water. Jump in to fill Robin’s Hazard Suit and start cleaning up the chemical spills. When the area is clear, put out the fires too.
    38. On the other side of the fires are bouncing bricks. Construct them to find a Robin symbol and his Acrobat Suit. Grab the new suit, and attach an Acrobat Pole to the Pole Slot on the back wall, the slot is a Lego object colored white and blue near floating studs. You can attach the pole by targeting the slot the same way you’d use a grappling hook or Batarang.
    39. Crossing the gap, jump down into the new area and use the white and blue Acrobat Ball transformer on the ground. Move the Acrobat Ball left inside the transformer to raise a bridge so Batman can cross the gap. Keep moving until the bridge locks into place.
    40. Now that batman is across, he can interact with the leftmost electrified switch. Then interact with the center switch to find bouncing bricks. Build them and you’ll find Batman’s Power Suit.
    41. Equip the Power Suit, and continue down the steps on the right toward a locked gate with an orange handle. Interact with the handle while you have the Power Suit equipped and tap to rip the gate down.
    42. Through the gate, look to the background for a faint blue and white Lego pole. Robin with the Acrobat Suit can climb any poles marked with white and blue bricks – just like he can interact with Acrobat Ball Transformers marked with blue and white, or use Acrobat Pole Slots marked with blue and white.
    43. Climb the pole up to the raised catwalk and build the bouncing bricks to create a Grapple Point for Batman. Switch to Batman, grapple up, and then rip off the orange brick handle on the gate on your right.
    44. With the gate down, switch to Robin. He can wall-jump between narrow areas marked with blue and white. Start by jumping left, then wall-jumping right, then left, then right, then one final time left to reach the top. It might take some practice, but you’ll get the hang of it.
    45. At the top, attack the glowing white Lego object to lower a ladder for Batman. Climb up with the Bat and blast the silver Lego objects to your left.
    46. The base of the tower is your primary target. Destroying it will drop the tower and give Batman a way across the gap. Use the tower like a bridge, and continue moving right until another tower drops in your path, leaving behind a large silver Lego object. Blow it up with Batman’s rockets, of course!
    47. Inside the next room, you’ll find a fuzzy computer monitor in the center of two computer consoles. You might notice, those Lego brick computer desks have a lot of blue and white. Smash both, then build up the hopping bricks to create a new Acrobat Ball Transformer.
    48. Jump into the Ball Socket with Robin’s Acrobat Ball and you’ll have control of a cursor. Press the attack button to interact with anything on screen. If you want, you can click on the Joker’s face to see it move around.
    49. But, what you need to do is clock on the pipe-symbols in the top left and bottom right corners. Click each to shut off the steam above the computer, allowing you to run up the stairs and get by the ledge that was previously covered in steam.
    50. Following the catwalk right, you’ll find some goons and another orange handle that needs Batman’s Power Suit to pull off. Rip it down, then wall jump with Robin. At the top is a Ball Socket.
    51. Use Robin’s Acrobat Ball to manipulate the Ball Socket, giving you control of a platform you can raise up and down. Look across the screen, you can spot an electrified switch on the right, and Batman’s Electricity Suit below it.
    52. Lower the platform so Batman can reach the Electricity Suit, then switch to Batman and go for it. One handy thing, you won’t have to move the platform up. There’s a grapple point above the Bat Symbol holding the Electricity Suit.
    53. Grapple up after taking the Electricity Suit and flip the switch. Now Robin needs to get across to join Batman.
    54. Switch to Robin, and take the same route as Batman. Jump down to the lower gratings on the right, then grapple up. Keeping Robin selected, continue right into the new area. You’ll find several pools of chemicals, but above the first is an Acrobat Pole Socket.
    55. Attach the Acrobat Pole to the Socket, and effortlessly flip over the chemicals with Robin. On the other end, Robin can pull the switch to close the vats.
    56. Run across, and use Batman’s electricity suit to activate the switch at the end. Jump onto the pipe, and wait for the top to pop up so you can get onto a large metal crate – moved into position when you flipped that electricity switch.
    57. Landing on the metal crate will trigger a cutscene where Superman will arrive at the scene to help. When the cutscene ends, you’ll be able to play as Superman.
    58. Superman is different than Batman, he can put out fires with his ice breath and fly! Flying works just like Robin’s Hazard Suit, holding jump will let Superman float up.
    59. Switch to Superman and try out his new powers. Put out the fire to your left first, it’s a small one. Next, fly up to the back left corner where there’s an orange handle. Superman just naturally has super strength, so he can rip it down by himself.
    60. Tearing down the orange handle will produce a stream of water. Superman’s freeze breath can also freeze water. Go ahead and freeze the waterfall, allowing Batman and Robin to climb the frozen ice up to the second floor.
    61. Circle around the catwalks until you find some brown glowing Lego objects. Smash them all to find bouncing bricks, construct them to find Batman’s Power Suit. Despite all of Superman’s powers, he still can’t destroy silver Lego objects.
    62. Have Batman grab the Power Suit, then break the silver Lego object just right blocking off Robin’s Hazard Suit. Once the suit is free, grab it with Robin.
    63. Further right is a Lego brick wall. You won’t need Sensor Suit Batman now, Superman can use his X-Ray Vision to see inside. Interact with all three Lego objects inside to open the vats in the foreground.
    64. Remember the previous puzzle where each vat needs to be filled with each color of chemicals? Same thing here, just use Robin to soak up green, then fill the green vat. Do that same for orange and purple.
    65. The only problem? The vats aren’t easy to find. Below you’ll find orange and only orange. Green can be found on the raised area past the magma fountains. The purple vat is just further right of the green vat.
    66. Fill all three colors vats, and the two magma fountains (that are actually just chemicals) will turn into safe water. Use Superman’s ice breath to freeze both fountains, then use them as platforms to climb even higher.
    67. Ahead, you’ll find a barrier of electricity and an electrified switch. That means you need to go back and grab Batman’s Electricity Suit, it should be near the Robin Symbol back left of the chemical vats.
    68. Run through the electricity with Batman and flip the switch to let Robin and Superman through.
    69. Switch to Superman, and flow toward the gold Lego surface on the right, above a raging fire. Holding down the attack button will shoot Superman’s eye lasers, which he can use to cut out the glowing shape in the gold Lego bricks. Just move the laser near the dotted line until it’s all red.
    70. Once cut, water will spill out and let your partners join you up on the upper catwalk, which you can use to continue right. Crossing the bridge, it’ll fall, but you’ll be safe.
    71. Reaching another giant vat with a gold Lego surface, shoot out the pattern to spill water, then use Superman’s ice breath to freeze the waterfall.
    72. Climb the frozen waterfall, switch to Batman, and use the last switch to open the elevator on the right. Get everyone into the elevator and you’ll reach the roof of the building.
    73. On the roof, look right for the sign to topple – leaving a narrow path full of electricity. Cross over using Batman’s Electricity Suit to safely cross. On the right side of the sign, you’ll find the electricity switch. There’s just one problem, Batman can’t reach it.
    74. Switch to Superman and fly across, then use his heat vision on the two golden Lego objects below the electrified switch. Destroying both will produce enough bouncing bricks to construct a ladder for Batman. Grab Batman, climb the ladder, and turn off the electricity switch.
    75. With the electricity off, cross back over to the left side of the fallen sign to grab Batman’s Power Suit. You’ll need it to destroy silver Lego objects -back- on the right side.
    76. Return to the right side, and destroy the two silver Lego supports underneath the water tower. That that final job done, you’ll complete the level.
    77. Gotham City – The Juggernaut

    78. Back in Gotham City, follow your clear studs to the center park where a huge truck is driving in circles. Pull up aside the truck to trigger a cutscene.

    Well, I’m trying to track down one minikit cannister. Can you get which one? Yep, the Core Instability one. With the minikit detector on, there is an arrow pointing at the top of a tree. I’ve toppled all 3 statues, blown up all 10 searchlights, all 5 joker boxes, the cars, the billboards, and even the elusive helicopter, so I have no idea what is left, or why the arrow is pointing at a big nothing there. Any suggestions? I’ve played the level at least a dozen times now (no I’m not exaggerating), but have no idea what I am missing.


    On July 10, 2012 at 1:18 pm

    Hey mage11an:

    The big problem with most online guides for minikit cannisters is that they are -super- lazy and don’t bother showing the process to finding the minikit.

    I’ve checked it out myself, and I’ll go through all the possibilities:

    At the very start of the level, there’s a Two-Face jeep. Blow that up, and you’ll get one. Later one, there will be a yellow parked taxi, and another Two-Face jeep.

    After those vehicles, at the bend, there’s a Lego status holding a big key. Blast that. That might be the minikit you’re looking for.

    Here’s hoping,


    On July 11, 2012 at 6:57 pm

    Yeah, I eventually found a youtube that shows someone getting all the minikits. Again, I’ve shot the billboards, the cars, the statue arm with the key, the helicopter, and all 3 different statue bases. Nothing. Just that minikit detector arrow pointing at the top of a tree.

    One thing about this level that I find a little shoddy: in free-play, no matter which characters you select, you will only ever get to see batman in the bat-mobile, or robin on his motorcycle. Would it really have hurt them to give the option of rotating through the other characters and their vehicles (so long as the vehicles are armed).


    On July 12, 2012 at 10:41 am


    If you still can’t find the last minikit, I think I’ve finally figured it out. The last minikit — the one where the arrow is pointing at trees, is from one bad guy jeep on the road. The catch? You can’t destroy the statue, you’ll need to be on the first cycle around the city for this enemy car to appear.

    That’s my best guess, and it’s the last one I found — and the arrows were pointing at trees. Give it a try, it might be my last idea.



    On July 26, 2012 at 12:41 am

    Nope. Tried that. I think the location on top of the tree is a generic hiding spot of some kind, that doesn’t go with any particular trophy. Just for the ones that aren’t about blowing up specific targets, or where the minikits hide until you collect them… Anyway, I still don’t know what I need to do to collect this one. A made three trips round each lap, shooting to the right and shooting to the left. That’s 18 trips around the city. No idea what I could possibly be missing.


    On July 26, 2012 at 1:23 am

    Well, maybe that was it after all.
    Seems strange to put the arrow pointing at the tree instead of, oh, say… The truck you’re supposed to shoot. Still, compared to some of the games, that is only mildly annoying. (lego Indiana Jones 2 was full of awful nonsense that made me just give up)


    On July 20, 2014 at 3:50 pm

    To get the minikit near the tree: destroy fist two ace car at start, then do not shoot fist statue wait and the second two face car will appear, destroy it. That how I got it.
