Objective 1: Extinguish Firefly
Safe above the flames, that pyromaniac Firefly fires blasts down upon you. To get him down, you need to build a water cannon to help extinguish the flames. Start by busting all of the nearby LEGO objects to find some bricks that you can build into the water cannon. Once the cannon is built, interact with it to hop on board and take aim at the flames. After you’ve put out some of the inferno, Firefly comes down to your level. Quickly unleash some justice on him and take him down. Once the firebug retreats, rebuild the water cannon and fully extinguish the flames.
During the fight, you are accosted by some goons. Take this opportunity to perform three ground finishers and complete the combat challenge for the level. In addition to completing that challenge here, be sure to check the path to the left of the stairs for a Joker prop to smash.
Combat Challenge: Finishers
The Joker Smash Challenge: 1 / 3
Objective 2: Defeat Cheetah
With Firefly’s flames extinguished, head up the stairs where you are soon confronted by Cheetah. Lucky for you, this area is quite large and you can easily outrun her. Take advantage of this and run from the left to the right side destroying the LEGO objects you come across for studs, as well as The Joker props you find on the left and right sides of the platform.
The Joker Smash Challenge: 3 / 3
With that out of the way, it’s time to take on Cheetah herself. If you’re having difficulty dealing damage to her without getting hit yourself, take your time and counter her attacks. After a few quick barrages, Cheetah retreats. When she does, you can count on several goons to rappel into the area to try their hand at stopping you.
Once you’ve defeated the goons, keep an eye out for a red reticle to appear on the ground. This marks where Cheetah attempts to pounce on you, so get out of the way! Dish out some swift justice on her and once again she retreats, leaving goons to do her dirty work. This cycle repeats one more time.
After Cheetah retreats for the third time, she perches above the hologram of the earth. This causes some panels to come crashing down, activating a laser in the process. Build the bricks that come from the broken panels into a deflection spot that Wonder Woman can use.
Deflect the laser toward Cheetah, who is conveniently standing atop a gold LEGO piece (3DS only). Aim the laser at the gold LEGO she is standing on to have her attack you one last time. Finish her off with some quick hand to hand combat to complete the level.
