Mission 6-1: Brainiacs Ship

Objective 1: Deactivate the Force Field

From the start of the level, switch to Lex Luthor and equip his Hazard Suit. Climb to the top platform along the back wall. You find a lot of toxic goo with a lever set in the middle of the mess. Throw the lever to bring down the force field over the small alcove to the right.

Don’t release the lever! Instead, switch characters and equip Batman with his Sensor Suit. Head to the right and smash The Joker prop you find there. Now activate Detective Mode and search the back wall beneath the alcove to locate a grapple point. Grapple up to the ledge and build the bouncing LEGO bricks you find into a lever. Throw the lever to deactivate a force field to the right that was covering one of Brainiac’s tentacles.

Objective 2: Cut through Brainiac’s Tentacles

Continue to the right past the skull and you come across a large piece of glass LEGO. Equip Batman with his Sonar Suit and shatter the LEGO glass using the suit’s sonic abilities. Once the glass is shattered, build the LEGO bricks that spill out from it into a sawblade that cuts its way through the tentacles to the right.

Objective 3: Shut Down the Energy Gate

Head right until a giant skull takes notice of you. Besides that monstrosity, be ready to contend with some goons. After you’ve taken out the baddies there, switch to Batman and equip his Electricity Suit. To the right of the giant skull, there is a path with an active electrical terminal. Drain it of its energy. This also causes the nearby tentacles to retreat, allowing you to access The Joker prop at the top of the path. Smash it!

At the top of the path, there is also a set of hyper strength handles. Take control of Lex Luthor and switch to his Big LEGO form. Pull on the handles to rip the panel from the wall. This exposes some gold LEGO pipes. Destroy them using a character with a laser. This causes one of the teeth to fall from the gate in the skull’s mouth, as well as calls on some goons.

Once the goons have been put down, head to the left side of the skull and locate the electrical terminal on the path there. Discharge your electricity into the terminal by attacking it with a ranged attack using Batman’s Electric Suit to make the tentacles retreat. Now you can continue up the path and destroy The Joker prop at the top.

The Joker Smash Challenge: 3 / 3

Hack the computer terminal nearby. After successfully hacking the system, a door at the top of path lowers. Another set of gold LEGO pipes is revealed. Destroy the gold LEGO using a laser. This causes the gate in the mouth of the skull to vanish, allowing you to access the switch inside.

After throwing the switch, some goons, coming from the left door, attempt to stop you. Once you’ve dealt with them, a door to the right of the skull lowers. Pass through it to exit the level.
