For this level, the level specific item is SPACESHIPS.
WayneTech Cache #1 (00:18):

At the start of the mission in the museum, zip up to the floor above you on the left side. Follow the trail of Gold Studs to the correct platform. Up here, use the Batclaw to pull the pipe loose, releasing water and opening access to the WayneTech Cache.
Spaceship #1 (00:43):

When rescuing the partygoer on the right side of the museum’s starting area, look just to the right of them. The Spaceship is sitting in front of the display.
WayneTech Cache #2 (00:53):

In the next display along — directly to the right of Spaceship #1 — move the board across to reveal the WayneTech Cache hidden behind it.
WayneTech Cache #3 (01:24):

In the room where you first learn to use the Grapple Drone, deploy it again. Fly the drone to the right and land it on the small platform holding the WayneTech Cache. Once it’s placed, grapple up to collect it.
WayneTech Cache #4 (01:54):

When you reach the three partygoers hanging from a cage in front of you, turn right instead of going forward. At the end of the corner walkway is the WayneTech Cache.
Spaceship #2 (02:31):

Near WayneTech Cache #4, enter the sandy beach section of the room. Look opposite the burning ship — the Spaceship is positioned up above you.
Spaceship #3 (02:39):

After firing the cannon to open the next room with the burning floor, use the Drone to cross the first gap. Then call the Drone again and place it high above you as a perch point. Zip up to it — the Spaceship is sitting on top of the large statue.
Spaceship #4 (02:48):

In the hallway where you weave between bookcases to avoid the fire on the floor, look to the back‑right corner. The Spaceship is attached to the poster on the wall.
WayneTech Cache #5 (02:58):

When you catch up to Firefly in front of the SPACE door, activate your Drone and place it as a perch point on the left side of the area. Zip up to reach the upper platform — the WayneTech Cache is on top.
Red Brick (03:32):

In the same area as WayneTech Cache #5, head right into the room with the large globe in the centre. Interact with all the lights shining on the globe until they display the red planet. Once all lights match, the Red Brick becomes accessible.
Spaceship #5 (04:05):

After entering the code, proceed into the next room. The final Spaceship is circling above you in the air — simply wait for it to pass overhead and grab it.
