Objective 1: Defeat Brainiac!
Immediately, you’re assaulted by three goons. Deal out some swift justice, while making sure to perform ground finishers to complete the Combat Challenge for the level. Once all the goons have been dealt with, Brainiac picks up the nearby trailer and drops it. Build the LEGO bricks that spill out from the wreck into a pad to reflect Brainiac’s beam back at him.
Combat Challenge: Finishers
Once the pad is completed, Brainiac begins to follow you overhead and fires his beam down on you. Lure him over the pad to reflect his weapon back at him, shrinking his craft in the process. Quickly unleash your attack on Brainiac while he is grounded.
After taking some damage, Brainiac takes to the sky. Once again, he deploys some goons to do his dirty work for him. Before you deal with them, head to the west and destroy The Joker prop near the bistro. Then destroy the next Joker prop to the left of the cathedral. Next, head south of the cathedral to smash another Joker prop. Finally, the last Joker prop is located northeast of the cathedral.
The Joker Smash Challenge: 4 / 4
Defeat Brainiac’s goons and he lifts the gazebo into the air. When he drops the gazebo, build the bricks from it into another device to reflect his beam back at him. As before, lure him into firing his beam at the device, shrinking himself in the process. When his craft shrinks down, attack it until he returns to normal size.
One more time! Defeat Brainiac’s goons and he throws a fruit stand. Build these bricks again into a device to reflect his beam back at him. Shrunk down, the baddie isn’t so dangerous. Quickly smash up his ship and send him packing!
