In case you didn’t find all collectibles in the first story playthrough, don’t worry. You can still get it. Play the story to Mission 6: Shreck’s Department Store, where you restore the Batcave.

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.

Batcave Trophy: Rubber Ducks

Find and destroy 5 Rubber Ducks in Mission 7: The Penguin to receive the Batcave Trophy: Rubber Ducks. Each adds up to the total of 170 Trophy Collectibles. Therefore, you will have 5 of 170 Trophy Collectibles after destroying all five Rubber Ducks.

Here’s where they are:

Red Brick: Gothic

In Mission 7: The Penguin, there is a storage room section. Find the underground vent and go to the other side, where the Red Brick is trapped in a cage. Cut the red umbrella out of the showcase and place it on the mechanism. With the umbrella pointing to the Red Brick’s cage, jump onto the mechanism to destroy the cage and get the Red Brick.

Wayne Tech Caches

Find and open 5 Wayne Tech Caches in Mission 7: The Penguin to receive a total of five WayneTech Chips.

Here’s where they are:

Go to the Zoo

Back in the open world, head to the Zoo in the Old Gotham South district. Grapple over the entrance gate and head to the main building at the back.

Investigate the Calls for Help

Near the main building, someone will call out for help. They are trapped below a sign. Lift it to rescue a Zookeeper.

Free the Trapped Zookeeper

To free the Zookeeper in the pipe, you need Jim Gordon’s Foam Sprayer. Switch to Jim as a companion by either holding the down button on your controller or over the map & character menu. Then use the Foam Sprayer on the leaking pipe to free the other Zookeeper. The rescued Zookeepers will give you an animal tracker. The plan is for you to put the tracker on the escaped animals for the Zookeepers to pick them up.

The Escaped Zoo Animal activity is now unlocked and can be used to complete the open-world collectibles activities with a paw print symbol.

Find the Polar Bear

It’s time to practice the Escaped Zoo Animal activity. There are four in the Old Gotham South district, and the polar bear is one of them. The polar bear is on the south side of the zoo, inside a blue dumpster. Enter the yellow zone around the dumpster to make it come out.

The Polar Bear acts like a brute thug enemy. It will charge at you, and you have to dodge. Make it bump into a wall, so it gets confused. Approach it from behind to attach the animal tracker. Then, talk to the zookeeper.

Enter Arctic World through the Roof Window

The zookeeper has opened a hatch on the Arctic World building, and you can enter it through the roof. Switch to Catwoman and make her cut the glass. Draw a circle as Catwoman to cut the glass and create an opening. Interact with it to start the next part.

With only the open-world activity outside of the zoo, Mission 7: The Penguin starts as soon as you enter Arctic World.

Open the Security Door

Arctic World’s entrance hall has a shutter gate that prevents Batman from advancing. Good thing Catwoman, with her claws, can climb the walls to pull the lever at the top. This will open the shutter.

There are two stages:
When he flies, use the Bat Claw to get him down. When he protects himself with the umbrella, use Catwoman’s Whip!
When he’s driving his Duck Mobile, you can use Catwoman’s Whip on the bombs and Batman’s Bat Claw on the propeller.

It all began in the ’80s when I was just 7 years old. Starting with basic arcade games, I soon delved into titles like Loom and Monkey Island by Lucasarts. Throughout the years, as I indulged in more and more games, I consistently sought clear guides to swiftly navigate my gameplay. Now, it’s my turn to contribute back to the community.
