How to Replay a Mission
In case you didn’t find all collectibles in the first story playthrough, don’t worry. You can still get it. Play the story until this mission here, Mission 6: Shreck’s Department Store.
Then, travel to the Batcave and interact with the computer at the top, next to the red batphone. Here you can select the mission you would like to play again.
You will also see the status. If the box is ticked: Congratulations, you’ve found all the collectibles in this mission. If not, there is still work to be done!
Batcave Trophy: Cat Heads
Find and destroy 5 Cat Heads in this Mission to receive the Batcave Trophy: Cat Heads. Each adds up to the total of 170 Trophy Collectibles. Therefore, you will have 5 of 170 Trophy Collectibles after destroying all five Cat Heads.
Here’s where they are:
Red Brick: Feline
Play and win the video game to get the Red Brick: Feline.
Wayne Tech Caches
Find and open 5 Wayne Tech Caches in this Mission to receive a total of five WayneTech Chips.
Here’s where they are:
Chapter One Complete
At the end of Mission 5: The Red Hood Gang, Chapter 1 is complete. Batman and Jim Gordon are heading out to find leads for Mission 6. There is just one more thing that has to be done…
Go to GCPD on Tricorner
Return to Tricorner Island to visit the GCPD. You can fast-travel to the Tricorner Subwayne. It’s right below the GCPD building.
Build the Device
Head to the top of the GCPD building to build a device. I guess we all know what device this is! Destroy everything to find the parts for the Batsignal. Interact with it to continue with the story.
Home Sweet Home
Improve the Batcave
Garage
There are four Batcave improvements. I go for the easiest one first: Right in the center ring is a console you can interact with. This is the Garage. Buy the Batman’89 for 1000 Studs.
Challenge Board
Grapple up from the round center garage platform to find the area of the Challenge Board.
Repair it by placing the two batteries into the generator and interacting with the console. Here you can collect studs for completed challenges. Complete all the challenges to get a nice Gotham City picture on the blackboard in the background.

Grapple up from the round center garage platform to find the area of the Challenge Board.
Suit Vault
Another improvement project is on the cave’s ground floor near the exit bridge. Interact with the digger’s console to expand the Batcave. Build a Suit Vault for 1,000 Studs! I’m looking forward to filling this massive Suit Vault!

Answer the Batphone
Pick up the phone at the command center its a call from “Bat-Mite”
Follow the Blue Bat
Follow the blue bat to a brick wall by the elevator with the big Batman sign. Interact with the brick wall.
Collect the New Gadget
Head down to where the gadget workbench is to pick up the Explosive Spray to use it on the brick wall.
Enter the Strange Shop
Go through the new passage to find the Bat-Mite store. Enter the shop to buy new suits and decorative items for studs. Buy something from the shop and leave.
Answer the Batphone
Return to the Batphone to answer it.
Minikit 3 of 10
There are 10 Minikits in the Batcave. Each collected Minikit adds to the Trophy Collectibles counter. By collecting 10, you will have collected 10 of the total of 170 Trophy Collectibles. This is an open-world objective, not a mission objective. You can’t pick them all up in the mission.
I’ve already picked up two Minikits in Mission 5: The Red Hood Gang, while analysing the bear in the Batcave. This third one is on the upper outer ring. Grapple up next to it and then glide to land on the ring to get it.
WayneTech Cache 2 of 10
Find and open 10 Wayne Tech Caches in the Batcave to receive 10 WayneTech Chips as a reward. This is an open-world objective, not a mission objective. You can’t pick them all up in the mission.
After discovering the first WayneTech Cache during Mission 5: The Red Hood Gang as part of the story, you can find this WayneTech Cache below the bridge towards the elevator.
Disrupted Debate
Stop 3 Mime Vans
The mission continues with Batman chasing a Mime Van, followed by the introduction of the Batmobile’s rockets and grapples to take down vehicles. Fire the rockets a couple of times to remove the vehicle’s armour. Once the van is burning, you can use the grapple to stop it.
The other two vans have mission markers numbered 1 and 2. Stop them the same way as the first one: Fire the rockets, then use the grapple to stop them.
Go to the Car Dealership
The Car Dealership is at The Cauldron South in the northwest of South Island.
Find the Mime Van
There are some foam piles ahead. Destroy everything and pull open the crate on the forklift with Batman’s Bat Claw. You can then build a water cannon.
Pick up the hose and plug it into the water spout. Then, use the cannon to wash the foam off, then vans to find the Mime Van. Inspect the Mime Van to continue with the mission. The Mime Van will drive off, and you will have to stop it the same way you did with the other three.
Go to Shreck’s Department Store
Shreck’s Department is at Old Gotham North in the east of South Island. The Mime Van driver is dangling inside a sign. Interact with them to continue with the mission.
Shreck’s Department Store – Mission 6 Start
Entering Mission 6: Shreck’s Department Store has officially started. You will play with Batman and Catwoman.
Look for a Way Out
Now playing with Catwoman and Batman on my side, you’ll be introduced to Catwoman’s Whip ability. She can unscrew and spin objects. Use Whip to unscrew the yellow screw at the top. Then, whip the shutter mechanism multiple times to open it.
There is another shutter here. Use Catwoman’s Whip multiple times on the shutter mechanism to open it. In the next room is a picture frame that you can inspect. It shows how the statues have to be positioned for the big silver-framed painting to open.
Use Catwoman’s Whip again to position the statues so they look forward. One Whip is one-quarter turn.
Find the Elevator
Go through the crawlspace behind the painting. There are some Mine Thugs at the other end. After defeating them, destroy everything to build a grapple plug to the door. Now you can use Batman’s Bat Claw to pull the door open.
WayneTech Cache 2 of 5
There is a WayneTech Cache in this room, locked behind a glass door that requires a key. The key is in the next room (after building and pulling the grapple plug on the door). Destroy the desk there to find a green key. Return to the room with the glass door, and open it with the key to get access to the WayneTech Cache.
In the next room, you can open up two crawl spaces by pulling them open with the Bat Claw to sneak past the camera and get a better vantage point for the next room. After defeating the thugs in this room, return to the camera to pick up the blue stud. Then, open the next door to find the elevator. You can press the down button to continue.
Look for a Way Out
The elevator breaks down, but there is a brick wall. Like in the Bat Cave, use Batman’s Explosive Spray to blow your way through. You will find two targets that you can shoot with the Batarang.
This will make the elevator go further down. Exit by grapple into a two-level room with a grand staircase. Pull open the vent with Batman’s Bat Claw.
The vent is too small for Batman to pass through. Call Catwoman’s Kitty. It can enter small vents. As Kitty goes through the vent and presses the red button on the other side. This will open the shutter.
Recall Kitty and play as Batman and Catwoman again, to go through the crawlspace in this room. At the other end is a big shop room with Mimes posing as mannequins for an ambush. Just grapple with the other side of the room to take them down from behind. There is a blue stud under the crawlspace you came through.
WayneTech Cache 3 of 5
On one side of the room, look for a trail of golden studs leading to a crawlspace (you have to destroy the box to get access). At the other end, summon a Kitty, go through the vent, and press the red button to open the shutter.
Enter the storage room and push the cart with the boxes to the back so you can reach the WayneTech Cache. Stay on the cache level, destroy the boxes to the left to reach a purple stud.
In the shop, use Catwoman’s Whip on the two yellow screws next to the “Fashion” passage shutter. This will unlock a Kitty vent. Send Kitty through to notice that a thug is standing right in front of the button. Use Kitty’s Meow ability to make the thug look for the noise. Now you can press the button.
Find a Way Past the Doors
Now Batman and Catwoman can enter the “Fashion” section. Just press the next red button to open the shop’s shutter to a small mall corridor with a PETS shop, SHREK’S shop, and a GADGETS shop. Shoot the two targets above the Shreck’s sign for it to fall down, revealing the crawlspace behind.
Red Brick: Feline
Notice the golden stud line beneath the GADGETS sign? Pick up the power cable there and plug it in.
This will start the game. You are starting as the green kitty in the top left corner. Use the arrows to steer the green kitty to the red dot. But avoid the dog! The Red Brick: Feline is your reward.
Go through the vent and defeat the enemies on the other side, and continue on to the SALE GOODS area.
WayneTech Cache 5 of 5
In the same area, head over to the TOYS section and stand on the red button. You will see and hear a tune on the piano in front of you. Play the same tune. From left to right, stand on the piano keys in this order:
3-4-5-8-7
I highlighted the order in the screenshot below. The curtain will open, revealing the last WayneTech Cache of this mission.
In the next room, destroy everything. Then summon Catwoman’s Kitty and go through the Kitty vent. Collect the key on the desk and return to Catwoman.
Use the key on the padlock and then move the music box with Catwoman’s Whip until the cat jumps out of the box.
Batman is next. Pull the yellow grapple plug with the Bat Claw. Now you have all the parts you need to build an amplifier to escape Shreck’s Department Store. Rock this place!
