Objective 1: Topple the Tower
Brainiac is more than a little upset at having to change his plans. In response to your intervention, he deploys goons all around you. Now is as good a time as any to work toward the Combat Challenge for the level by using counters often. After you’ve dealt with the last goon, the door on the horse-driven coach at the base of the Eiffel Tower swings open. One more goon hops out from the coach, deal with him accordingly.
Combat Challenge: Counters
Use a laser to destroy the gold LEGO inside of the coach. The resulting explosion topples the Eiffel Tower as well. Before you make your way north, be sure to check the southwest corner of the courtyard and smash the Lex Luthor prop you find in the corner.

Objective 2: Destroy the Roadblocks
Make your way north and cross the river. Brainiac is waiting there and enlarges some objects to bar your path. In addition to being a nuisance, the villain deploys more goons to attack you. Keep up with fierce combos to make quick work of these foes. After you’ve depleted their reserves, a group of cyclists passes by. Brainiac decides to enlarge them as well. Conveniently for you, they crash through the fallen sign across the road to the east.
Before moving on, be sure to destroy the Lex Luthor prop on the west side of the area. With that destroyed, there is still one thing left to do here. Have Superman run on the speed spot at the north end of the courtyard to bring down the nearby gate. Pass through these gates and The Joker Card is yours to claim.

The Joker Card
Make your way east until you come to a dead end. Use the laser ability to cut through the brick wall and reveal some LEGO bricks. Build these into a silver LEGO rider to sit upon the nearby horse statue. Even though you just completed that shiny silver rider, use a character with a Demolition Suit to blow it to smithereens.
Objective 3: Defeat Brainiac’s Goons
Continue east past where the statue once stood. Here you are accosted once again by Brainiac’s goons. Your first instinct is to deal out some swift justice. You would be correct, if you’ve already completed all of the challenges. If not, be sure to circle the Arc de Triomphe, because the final Lex Luthor prop is on the east side of the structure. In addition, destroy everything possible to collect any remaining studs that you need. Once you’re ready to continue on, take out all of the goons.
