LEGO Batman Legacy Mission 3 New Beginnings Walkthrough – All Collectibles, Surfboards & Red Brick

Mission 3: New Beginnings is the first mission of Chapter 1 in LEGO Batman: Legacy of the Dark Knight, picking up after Bruce Wayne’s return to Gotham. This walkthrough covers everything in the mission – from following the bats through the neglected Wayne Manor grounds, descending into the cave, and chasing Detective Flass through the Gotham Docks. Along the way, you can collect all 5 Surfboards for the Batcave Trophy and grab the Nautical Red Brick before the final interrogation scene.

Apart from the yellow Skill Brick at the end of the mission, you can also find:

Batcave Trophy: Surfboards

Find and destroy 5 Surfboards in this Mission to receive the Batcave Trophy: Surfboards. Each tree adds up to the total of 170 Trophy Collectibles. Therefore, you will have 5 of 170 Trophy Collectibles after destroying all five Surfboards.

Here’s where they are:

Red Brick: Nautical

The Red Brick is in the locked cabin at the end of the mission, before interrogating Flass.

Follow the Bat

Mission 3 is the first mission in Chapter 1, also named The Batcave, where Bruce and Alfred return to the Wayne Manor Garden grounds, now in a neglected state. Follow the bats that are flying around on the Wayne Manor grounds. You can also use “Detect” to find them. Be nice to the “W” hedge in front of the gate leading to the well of Mission 1: League of Shadows, and water it on the way there.

There is no way to cross the river. But there is a tree. Shoot it three times with the shuriken to make it drop down to serve as a bridge. Cross over and move through the crawlspace to reach the well. There is a blue stud behind the well.

Explore the Cave

Use the crawlspace at the bottom of the well to advance into the batcave. Shoot the base of the three stalagmites in your way to cross over to a ledge. Shimmy to the left, along the rail, and climb up the tall stalagmite.

Reach the Wayne Manor Foundations

Follow the silver studs to a light and other scrap. Destroy everything to build a big spotlight. Use it and direct it onto the bats. Before using it, look for a grapple point in the area. It will lead to a purple stud.

Chase Detective Flass

Bruce has now become Batman – finally. Fight the thugs, then team up with Jim Gordon. Before entering the building, have a look around behind the stacked containers in the courtyard to find a blue stud.

In the building, shoot a batarang at the container target ahead to drop it into the water. Now you can get across.

In the next section is a nasty yellow machine blocking the passage. Switch to Jim Gordon. He has a Foam Sprayer. Aim and shoot at the machine cogs as if you would with a shuriken/batarang. Go through to the other side, destroy everything, and you will find one blue and one purple stud.
