Mission 3-1: The Bat-rocket Hangar

Objective 1: Find the Sonar Suit

Make your way to the far left corner where you find a Joker prop to smash. Once that is done, go back to the start and head up the stairs.

The Joker Smash Challenge: 1 / 3

After climbing the stairs, you pass by a lever locked behind a panel of glass. You need to have the Sonar Suit to break the glass. Continue onward and find the silver LEGO crate. Destroy this crate by using Batman’s Demolition Suit. Build the bricks left behind into a computer console. Now, switch to Robin and equip his Techno Suit. Hack the computer console to roll out a tram with part of the Bat-rocket on board.

Use the grapple hook on the side of the tram to climb up. Once on the tram, use the spinner switch to place the cockpit glass onto the Bat-rocket. This also causes the Sonar Suit Token to appear nearby. Pick up the Token, which equips Batman with the Sonar Suit. Now head back to the Sonar Glass near the stairs. Use your newly acquired sonic ability to shatter the LEGO glass. Throw the lever within to extend a bridge so you can cross the chasm to your right.

Unlocked: Batman (Sonar Suit)

Objective 2: Find the Space Suit

After crossing the bridge, equip Batman with his Demolition Suit and destroy the silver LEGO that you come across. This causes Attract pieces to spill out. Now, as Robin, equip the Hazard Suit and collect the fallen Attract pieces. Place these pieces into the nearby Attract Station to build a fan. Jump into the updraft of the fan to ascend to the platform above.

Once on the platform, follow the narrow path to the left and locate a green LEGO wall. Equip Batman with his Sensor Suit and examine the wall. While Batman peers into the wall, use Robin to turn the valves, align the pipeline, and drain the fuel tank to your right.

Use the Sensor Suit’s Detective Mode to examine the now drained holding tank and reveal a glass LEGO door. Equip Batman with his Sonar Suit and shatter the glass LEGO. Grab the glowing keycard on the floor of the fuel tank and place it into the computer terminal to the right of the fuel tank. Doing so lowers a bridge nearby. Cross this bridge to find a platform where another Joker prop is waiting to be destroyed. After smashing The Joker prop, destroy the large silver LEGO wall to reveal a dark alcove. Equip Robin with his Illumination Suit and enter the darkness. Now that the area is lit up, shatter the case you find inside and claim the Space Suit Token that falls out.

Objective 3: Complete the Bat-rocket

Equipped with the Space Suit, use Batman’s laser to destroy the gold LEGO tank nearby. Build the bricks left behind into a refuel station. Interact with the station to refuel the Space Suit’s jetpack. Use the jetpack to fly up to the platform above the fuel tank to the left. Once on the platform, use your laser to destroy the nearby gold LEGO panel, which allows Robin to join you. Switch to Robin and target the nearby twirl pole socket and throw your baton into it. Swing across the twirl poles to access a higher platform. Smash all of the LEGO objects on the platform and build the bricks that fall into a grapple handle so that Batman can join you. Among these smashables you also find the final Joker prop!

The Joker Smash Challenge: 3 / 3

As Batman, interact with the gold LEGO wall. Trace the outline with his laser to peel back a section of the wall, revealing a computer console. Now, switch back to Robin and equip his Techno Suit to hack the computer console. After hacking the console, the final part of the Bat-rocket is installed and the bridge to the cockpit extends. Cross the bridge and enter the Bat-rocket to complete the stage.
