The Iceberg Lounge mission packs 11 collectibles – five Disco Balls, five WayneTech Caches and a Red Brick, scattered across Falcone’s nightclub. This guide highlights where to find each collectible as you progress, grappling onto lighting rigs, crawling vents to reach hidden caches, squeezing through blue rollers behind the ball pit, using Gordon’s skill to reach the locked cache and obtaining the Red Brick that sits in a safe in the VIP lounge. Collect everything to unlock the Batcave decors and a new suit color.

You’ll find the fourth disco ball suspended above the second ball pit area, defeat the enemies in the ball pit and shoot the disco ball with the batarang.

At the third ball pit, defeat the enemies and before progressing to the next section, open the floor vent in the ball pit as shown in the above image to access the room behind the pit where the fourth WayneTech Cache is located.
WayneTech Cache 5
When you reach the area with the two big speakers, turn right and look up to find a lock – destroy it with a batarang, then grapple up to claim the fifth WayneTech Cache.
Disco Ball 5
After a long slide past the speakers, you enter a room where you must build a drill to reach the lower level, before doing so, the right section of the room contains the final disco ball collective so make sure to claim it.
This covers all the collectibles throughout the Iceberg Lounge mission and this will unlock a new suit color and Batcave decors.
