The Remote Terminal at this location is located near the third large tube of the beach. It is locked with a gold lock, so you will have to destroy it using a heat character. This one is a Remote Terminal for water vehicles.
After activating the Remote Terminal, you can find this character by going to the right of the Remote Terminal. In his boss fight, he will jump and use stomp attacks to create shockwaves. Dodge them and hit him to remove a heart. Repeat this three times to defeat Bane. When you remove his three hearts, you can buy him for 125,000 studs.
After climbing the third wall of the eighth Gold Brick, you will find a Gold Door ahead. 70 Gold Bricks are needed to build it. When you have 70 Gold Bricks, build the Gold Door to reveal Aquaman. He costs 125,000 studs. (It is highly recommended to buy this character, since he can be useful for Free Play.)
On the far right of the walkway above the northern part of the beach, you will find a mystery box. Use the Riddler to open it and reveal this Red Brick, which costs 50,000 studs.
Use a flying and laser character to destroy a gold plate on the head of a giant statue holding up a pipe at the north end of the central island to reveal this Gold Brick.
Below the previous Gold Brick, you will find a panel with the Power Suit. Put it on as Batman, destroy a silver object guarding a grappling point on a wall to the left, and use a grappling hook to climb up the wall and climb another wall to reach the large pipes. Destroy a silver lid on the right and follow the path of studs climbing walls and hanging from ceilings until you reach a silver cage with the Gold Brick. Use an explosive rocket to destroy the silver cage and obtain this Gold Brick.
After purchasing the Joker's Helicopter, hop on it and complete a flying race to obtain this Gold Brick.
East of the Remote Terminal of the beach, you will find this Gold Brick inside a golden cage on a small rooftop. Use a flying character to reach the small rooftop and then use a laser character to destroy the golden cage and get this Gold Brick.
A little to the bottom right of the previous Gold Brick, you will find this Gold Brick on top of a building that can only be reached using a flying character. Use a laser character to destroy a golden cage and obtain this Gold Brick.
Going north of the previous Gold Brick with a flying character, you will find this Gold Brick locked in a golden cage on top of another building. Use a laser character to destroy a golden cage and obtain this Gold Brick.
Go to the bottom of the previous Gold Brick and you will find a panel with the Magnet Suit. Put it on as Robin, scale a blue metal wall, then use the magnet to pull out a metal cover and put on the Acrobat Suit. Climb between blue and white walls and do stunts on sticks until you reach a platform. Transform into a trackball, move to the platform and run up to open the fences on the left. Go down a slide while still in trackball and follow the path of studs until you find this Gold Brick locked in a container. Move on the platform still in trackball and run up to the top left to open the container with this Gold Brick.
After getting the previous Gold Brick, jump down onto the street and go right to find a panel with the Ice Suit. Put it on as Robin, freeze the water from the broken fire hydrants and climb up the left wall and jump over the frozen water until you reach the right wall. Climb the wall and use a grappling hook to reach two broken fire hydrants and a frozen air conditioner. Since you have the Ice Suit, the air conditioning shouldn't freeze you. Freeze the water in the two fire hydrants on the right and go up the ramp on the left and jump over the frozen water until you reach the wall on the right. Follow the path of studs, past two freezer air conditioners, and climb a wall to reach an ice container with the Gold Brick. Shoot the Ice Switch above with the Freeze Gun to activate it and open the ice container with the Gold Brick.
In the lot in front of a building southeast of the Remote Terminal of the beach, you will find a panel with the Bat Suit. Put it on as Batman, destroy a glass container with the wave gun and use a grappling hook to reach the ceiling. Destroy a glass wall with the wave gun and follow the path of studs climbing normal walls until you reach a part where you have to glide across a gap and reach a platform. When you cross the gap, climb a wall, destroy the glass container on the right and step on a button to raise a wall. Climb the wall you raised and destroy a glass container to grab this Gold Brick.
When you are using the Remote Terminal, choose one of the water vehicles and board one of them to navigate through buoys. Complete a water race passing through buoys to get this Gold Brick.
At the spot on the wall that you need to climb to reach the second Gold Brick, go to the road ahead and then follow the road to the right. You will find this Civilian in Peril trapped in a fire hydrant. Freeze the water using a freezer character to save the civilian.
You will find this Civilian in Peril being harassed by a Penguin Goon behind a building near the northern part of the beach. Destroy the Penguin Goon to save this Civilian.
You'll find this Civilian in Peril being eaten by a carnivorous plant near the panel with the Bat Suit. Destroy the Carnivorous Plant's three weak points to save this civilian. (Recommended to do it with a Batarang.)
A little to the right of the News Reporter Van, you'll find this Civilian in Peril trapped in a block of ice. Use a laser character to thaw the ice and save this civilian.
