Objective 1: Find the Arctic Suit
To the left of the door leading to the hangar, there is a sphere spot. Equip Robin with the sphere suit and roll the device to lower the door to the left. When the door opens, claim the Token from inside to unlock Bronze Tiger.
Unlocked: Bronze Tiger
After claiming the Token for Bronze Tiger, switch to Martian Manhunter and fly high above the doorway leading to the control room. Claim the Token that is floating in the air to unlock Supergirl.
Unlocked: Supergirl
Head right and go into the hangar. Once you’re inside the hangar, Brainiac’s tentacles enter through a door along the east wall and wrap around the small space craft there. Near the entangled craft, you find a small keycard. Pick it up.
With the keycard in hand, climb the ladder in the southeast corner of the hangar. Once on the second floor, locate the computer console and insert the key card. When the nearby door opens, collect the Arctic Suit Token within.
Unlocked: Arctic Suit
Objective 2: Clear out the Tentacles
Go back to the ground floor and use the Arctic Suit to extinguish the flames near the space craft. Once the flames have been extinguished, use a character with a laser to destroy the gold LEGO box.
Build the bricks that spill out from the destroyed gold LEGO box into a Gold Brick device. Use the device to control a small craft that tows the spacecraft from the grasp of Brainiac’s tentacles.
Now that Brainiac’s tentacles are gone, the level pad is accessible. If you’re ready to do so, use the pad to advance to the next level.
